Swiss Meringue Buttercream Recipe

Swiss meringue buttercream is better in flavor and texture than American buttercream. Once you try it, you will want to use it on all of your cakes, cupcakes, cookies, everything! It is silky, pipes beautifully, and is stable (scroll down to see the fun design I made for my niece and nephews puppy-themed birthday party).

Swiss Meringue buttercream is my favorite of the meringue frostings because it is not overly sweet or difficult to make, and this method pasteurizes the egg whites in the process – Hooray!! It is simple enough to use for everyday baking but the flavor is special occasion worthy. This frosting makes me think of wedding cakes every time I make it!

Swiss Meringue Buttercream keeps really well overnight at room temperature without drying out or forming a crust like American buttercream will. You can completely assemble your cake ahead of time without taking up space in the refrigerator and it will look and taste just as good the next day!

Cook’s Tip for Swiss Meringue Buttercream:

Butter should be softened at room temperature for about 1 hour (more or less depending on your room temperature). You want it to be still slightly cool to the touch and not overly soft or warm. If it gets too soft, refrigerate for 10 minutes at a time.

How to Make Swiss Meringue Buttercream:

1. In a medium pot, add about 1-inch of water and bring to a simmer.

2. Thoroughly wash and dry the stainless steel mixing bowl from your stand mixer** (you don’t want any fat touching meringue). Add 7 egg whites and 2 cups sugar and whisk together.  Place mixing bowl over pot of barely simmering water, creating a seal over the pot (bowl should be over the steam, not touching water). Whisk constantly until sugar/egg white mixture reaches 160˚F (takes about 3 minutes). Sugar should be fully dissolved (you should not feel any sugar granules when rubbing mixture between fingers), and mixture will feel hot to the touch.

2. Wipe water from bottom of mixing bowl and transfer bowl to your stand mixer fitted with whisk attachment. Beat on medium-high speed until stiff glossy peaks form (about 15-20 minutes) and the bottom of the bowl feels completely at room temperature and not warm (important: if meringue is warm, it will melt the butter).

3. Once bowl is at room temperature, switch to paddle attachment, reduce to medium speed and add butter 1 Tbsp at a time, adding it just as fast as it can be absorbed by meringue. Once all butter is in, scrape down the bowl and continue beating until the buttercream has reached a thick whipped consistency (3 min on med-high speed). If it looks lumpy or liquid at all, keep beating until smooth, thick and whipped.

4. Add 2 tsp vanilla extract and 1/4 tsp salt then mix on med-high until incorporated (about 1 min).

P.S. The tiny amount of salt at the end gives this frosting incredible depth of flavor.

**It is ok to use a high speed electric hand mixer, but it may take 5-10 minutes longer of total mixing time. Also, a glass bowl will work but meringue may take longer to whip/cool down because glass retains heat longer.

Make-Ahead Tip: If not using Swiss Meringue Buttercream frosting the same day it is made, it can be refrigerated. If it has been chilled, bring back to room temperature then re-whip until smooth in texture before using.

Cost to Make: $6-$8

Ingredients

  • 7 large 210 grams or 7 oz egg whites
  • 2 cups 400 grams granulated sugar
  • 1 1/2 cups 3 sticks or 340 grams unsalted butter, softened*
  • 2 tsp vanilla extract
  • 1/4 tsp salt we use non-iodized fine sea salt

Instructions

  1. In a medium pot, add at least 1-inch of water and bring to simmer.
  2. Thoroughly wash and dry the stainless steel mixing bowl from your stand mixer* (you don't want grease touching meringue). Add 7 egg whites and 2 cups sugar and whisk together. Place mixing bowl over pot of barely simmering water, creating a seal over the pot (bowl should be over the steam, not touching water). Whisk constantly until mixture reaches 160˚F (takes about 3 min). Sugar should be fully dissolved (you should not feel any sugar granules when rubbing mixture between finger tips). Mixture will feel hot to the touch.
  3. Wipe water from bottom of mixing bowl and transfer bowl to stand mixer fitted with whisk attachment. Beat on medium-high speed until stiff glossy peaks form (about 15-20 min) and bottom of the bowl feels completely at room temp and not warm (important: warm meringue will melt the butter).
  4. Once bowl is at room temp, switch to paddle attachment, reduce to medium speed and add butter 1 Tbsp at a time, adding it just as fast as it is absorbed by meringue. Once all butter is in, scrape down the bowl and continue beating until it reaches a thick whipped consistency (3 min on med-high speed). If it looks lumpy or liquidy at all, keep beating until smooth, thick and whipped.
  5. Add 2 tsp vanilla extract and 1/4 tsp salt and mix on med-high until incorporated (about 1 min).

Recipe Notes

And here are the puppy cupcakes I made using this Swiss Buttercream for my niece and nephews birthday party! The kids LOVED them!! Here is the vanilla cupcakes base that I used for these. I used mini M&M’s on the eyes, a Hershey’s chocolate drop for the nose, then used a rolling pin and my hands to form the ears out of tootsie rolls and the tongue out of a similar shaped pink candy (similar to an airhead candy).

    Thanks Natasha! Really like your recipes. This is my first time making Swiss Meringue buttercream. The texture of mine is a bit rough. How could I make it smooth? Beat longer?
    Also, can I cut down the sugar ? Will it affect the texture? Thanks Reply

    • Natasha
      March 19, 2019

      Hi Pat, the typical fix for a rough texture in SMBC frosting is to continue mixing until the texture turns fluffy. It usually looks that way before it gets good 🙂 Reply

    Can’t wait to try this recipe! I’ve tried others, but they weren’t as sweet as I like. I was thinking of how this recipe takes a lot of egg whites, so what do you usually do with the yolks? I can never find a good use for them. Reply

    Hi Rachel.

    I haven’t seen any comments regarding dyeing the frosting. I’m wondering if you have any tips or tricks for me as I embark on decorating a birthday cake. I’m afraid that with vanilla extract in the original recipe, the dye may cause the frosting to breakdown and it will, therefore, not pipe well.

    I love reading the comments and answers. It helps immensely! Reply

    • Natashas Kitchen
      March 17, 2019

      Hi Tricia, you sure can! I think you could, but add a little color at a time until you reach your desired color while maintaining the consistency. I would recommend using a gel food coloring over a liquid one. Reply

        March 17, 2019

        I’ve tried it and it’s worked great. I’ve even “re-dyed” pink frosting to green for St. Pat’s! I agree with Natasha …the secret is to use gel coloring. Reply

    I really love this recipe because proportionally, it has a bit more sugar and a little less butter than other Swiss buttercream recipes. I admit that I crave the intense sweetness of American buttercream, but not the nasty gritty texture. On the other hand, I enjoy the silky smooth texture of Swiss buttercream but some recipes leave me feeling like I’m eating sticks of butter. This recipe is just perfect! Reply

Any thoughts? Thanks. Reply

    • Natashas Kitchen
      March 15, 2019

      Hi Holly, For chocolate SMBC, I have not experimented that way but from what I’m finding online is it may be possible! It is suggested to add 2/3 cup or up to 9 oz of melted, cooled chocolate, or you can add 3/4 cup of nutella. If you experiment, let me know how it goes! Reply

      I tried this last weekend and it worked! The chocolate flavor was so good! I just melted down chocolate chips then let them cool a bit. It kind of turned into a chocolate paste and was still a bit warm so I had to whip it a long time with the SMBC to let it cool and incorporate. Not sure if that’s the right method… It’s unclear to me how the chocolate can be melted and then cool to not become hard again…? Reply

      Hi Grace, I wish I had measured it that way, but I can only guess now – maybe 5 or 6 cups? It is enough to frost a 9″ two-layer cake. Reply

  • Rachel

    I tried making this for the cupcakes I had to frost, but when I made it, it turned into soup. I kept beating it hoping it would stiffen up, but no luck. My meringue was BEAUTIFUL until I added in the butter, then it went to soup. It had a great flavor, but just dripped off the spoon. I tried putting it in the fridge and seeing if that would help stiffen it up, but still soup. Would putting the meringue in the fridge for 15 minutes, and then adding the room temperature butter work better? I am not sure what I did wrong the first time, so any suggestions would be awesome 🙂 Thank you! 🙂 Reply

      Hi Rachel! I’m more than happy to troubleshoot! Is it very humid in your house? I haven’t heard of humidity being an issue, but I suppose it’s possible. I would suggest trying with the AC running to decrease humidity somewhat. Usually, if you are getting “soup”, it is due to either not allowing the egg whites to cool completely to room temperature before adding butter. If the meringue is warm at all, it will take longer to beat the frosting for it to reach the correct consistency. I would suggest beating it a few minutes longer next time before refrigerating and if refrigerating, do that for no longer than 20-30 minutes and then beat again. Reply

    I made this for valentines day and it was very good. Added strawberry, and chocolate to some of it. Yum. I was wondering if you can add more sugar or will it mess the recipe up? I’m gonna make my husbands birthday cake soon but he said he would want the icing to be sweeter. Reply

    • Natasha
      March 11, 2019

      Hi Ana, it can depend on what kind of cake you pair it with – if the cake is very sweet, the frosting will seem less so, but I think you could get away with adding more sugar here. I would start with 1/2 cup extra sugar. I’m so glad you enjoyed the frosting and I wish I could see a picture of your cake – sounds lovely! Reply

  • Chloe
    March 9, 2019

    Hi, do you know why my meringue isn’t able to get stiff peaks? its not stiff and not too soft, so I started adding in my butter. I don’t want the buttercream to be too sweet, so I only added in 1 stick and a half of butter. Now my buttercream won’t become thicker and the consistency isn’t right. It’s really runny and liquidy, so I’m not sure if it’s because I didn’t wait until the stiff peaks formed, or if I didn’t add in enough butter. I will probably add in more butter, hopefully that will fix it but do you know what went wrong? I kept mixing for a long time, even though it says be patient I waited for almost 30 minutes. Thank you! Reply

    • Natashas Kitchen
      March 9, 2019

      Hi Chloe, If it is runny and not pipe-able, the easiest fix is to beat the swiss meringue buttercream frosting a few minutes longer. It could be that the mixture did not cool completely to room temperature before adding butter, but it can be fixed with longer beating. I hope this helps Reply

      • Chloe
        March 10, 2019

        Thank you for the advice but the more I keep mixing it’s getting more liquidy? I’m going to add in more butter to see if it helps. Reply

    Hi Natasha,

    I’ve made this recipe several times and it’s always fabulous. I’ve been able to make it ahead and put it in the freezer and it comes out great. This last time it wasn’t looking as smooth as I liked so I put it in the mixer for a while but it came out too soft Should I have kept whipping it or did I whip it too much? Reply

    • Natasha
      March 9, 2019

      Hi Misty, thanks for sharing that it freezes well! I haven’t tried freezing but with SMBC frosting, beating longer will usually firm it up. Reply

        March 11, 2019

        Hi Natasha,

        You asked me to tell you how it turned out when I tried adding chocolate. It was amazing! I used about 6 ounces 78% and 3 ounces 65%. I added another 1/4 teaspoon of salt to cut the sweetness. Next time I will use all 78%. I liked it much better than using Nutella because that made it too sweet for me. Reply

    March 7, 2019

    Hi Rachel, if making the frosting ahead, it would be best to pipe onto the cupcakes and then refrigerate overnight, otherwise you would have to let the frosting come to room temp the next day and remix to get it to the whipped consistency. If you frost and then refrigerate, your cupcakes are done and the frosting will just as good once the cupcakes reach room temperature. Reply

  • Rachel
    March 7, 2019

    Can I make this frosting the night before, and then frost my cupcakes the next morning? I am making 240 cupcakes for a party, and will have the cupcakes made in advance, but didn’t want to frost them too early. Thanks! Reply

      March 8, 2019

      Hi Rachel, I have made this SMBC many times now. It’s my go to for frosting now. Just love it. I’ve found that piping the cup cakes the day before, refrigerate them, then take them out about 2 hours before you need them. (1 hour if it’s very warm weather). I’ve done this many times now with cupcakes and whole cakes. You will be less stressed on the day too, because that is a lot of cupcakes. Hope this helps. P.S. Another plan could be: 3 days before, you make the SMBC & pop in the fridge, the next day, make the cupcakes, cool them, whilst your SMBC is back out of the fridge softening a little bit, re whip it (that won’t take as long as it does to make it), then pipe them and pop back in the fridge. then the next day you’ve got them made, just have to take them out for your event. Just thought it might help. Good luck Reply

    I have never made swiss buttercream. I’ve taken about 3 years off from making cakes and always used shortening and butter flavor in the past (blech). I love that this one uses butter instead of shortening but looks to be pretty white and stable.

    Question: if I double the recipe, can I cook the egg whites and sugar, then split the mixture in half and whip a batch at a time? I’m sure my mixer won’t hold two batches once whipped but I wasn’t sure if the egg whites being cooled before whipping would make a difference. I know it doesn’t matter for regular whipped egg whites. Thought this would be a time saver.

    Thanks! Reply

    • Natashas Kitchen
      March 5, 2019

      Hi Melinda! I’m so happy you enjoyed that! If you wanted to double it, I would suggest making a double batch since it would take a really long time to cool to room temp and would overwhelm most mixers. Reply

      • Melinda
        March 5, 2019

        Natasha, I’m not sure you understood my question. I want to make a double batch. So i want to put 14 egg whites and 4 cups of sugar in the double boiler. Then split that in half, set aside one half and whip the other half (then add in the butter and such, finish it and remove it from the mixing bowl). I thought this would save time by not having to heat two batches of egg whites and sugar separately.

        The other half i set aside will be cooling while i whip and mix the first batch. If i whip and mix the mixture after it has sat and cooled a bit, will that cause issues?

        I realize i will have to clean my mixing bowl well between whipping or the 2nd batch definitely won’t whip. Reply

        • Natasha
          March 5, 2019

          Hi Melinda, I haven’t tried it that way (and I don’t foresee any issues), but since the mixture is heating up over steam, it may take twice as long to heat to the right temperature so I’m not sure that it will save time to do it that way. Great point about cleaning the bowl in between! Reply

  • Danielle

    Hi I have a question!
    The consistency of my Buttercream seems off. I’ve whipped the heck out of it but it just won’t get thicker. It’s like the consistency of soft whipped cream. I’ve tried refrigerating it for a couple hours and whipping it again but still doesn’t get thicker. I’m wondering if maybe I didn’t cook the egg whites and sugar hot enough or doubling the recipe threw it off? Reply

    • Natashas Kitchen
      March 4, 2019

      Hi Danielle, usually if you just continue beating it for another 2 to 3 minutes, it will thicken. You may run in to a problem if your butter was overly soft/partially melted, or if butter was added while the meringue was still warm. If that was the case, I would refrigerate 15 minutes and then continue mixing. Reply

    • Natasha
      February 26, 2019

      Hi Deepthi, I’m not sure I”m understanding your question correctly – SMBC has different ratios than American Buttercream, but for 4 cups sugar, I would recommend doubling the recipe and you would have to do it in 2 separate batches unless you had an industrial sized mixer. Hope that helps! Reply

          March 4, 2019

          Hi Deepthi, with this recipe it doesn’t make a difference because you will be heating the egg whites. They will heat up faster if they are at room temperature but it isn’t critical for the recipe. Reply

      February 25, 2019

      Hi Marley, it might be how you have your water bath set up – you should have the bowl sitting over the steam. make sure you are using a pot without a lip on the edge so the steam isn’t escaping or it will take forever for the mixture to heat up. Also, be sure your water is simmering underneath. Hope that helps troubleshoot. Reply

    • Natashas Kitchen
      February 23, 2019

      Hi Bianca, to be honest, I have not tried it with a hand mixer because it takes a really long time to whip and that would leave you with a very tired arm! I also haven’t come across any recipes that I can recall where a hand mixer was used – maybe solely because it is not easy to stand over it that long. I wish I could be more help but I just haven’t braved this with a hand mixer. Also, a hand mixer is not as efficient at whipping and cooling a mixture so you may have to whip even longer. Reply

    One more question. I’m wondering how much I will need to pipe a basket weave on the sides of my 2 layer cake along with large flowers on the top? I’m wondering if I will need to actually double this recipe? I may be hard to do 1.5 times the recipe unless I buy liquid whites. I can always double this and make something else to use the rest. 🙂 Reply

      Hi Holly, I wish I could tell you but I hadn’t measured it that way, but I can only guess that it may be enough. It is enough to frost a 9″ two-layer cake. If you end up doubling the recipe, you can use the leftovers for some cupcakes 🙂 Reply

    Hi Natasha,

    This is a wonderful frosting! I’ve added raspberry preserves and made a wonderful raspberry buttercream. I’d like to make a chocolate one but don’t know how much chocolate to add. What would you recommend? Reply

      February 19, 2019

      Hi Misty! For chocolate SMBC, I have not experimented that way but from what I’m finding online is it may be possible! It is suggested to add 2/3 cup or up to 9 oz of melted, cooled chocolate, or you can add 3/4 cup of nutella. If you experiment, let me know how it goes! Reply

    I have used your recipes in the past and just love them. I will be trying SMBC for a birthday cake and have been searching for recipes. Most are very similar to yours, but one I found adds 1/4 tsp cream of tartar. What are your thoughts on that? Thanks! I will use your recipe for the frosting, but am trying to decide if adding the cream of tartar will create a different result that might alter it too much. (I use it all the time when whipping egg whites.) Thanks. Reply

      February 19, 2019

      Hi Holly, no this recipe does not call for cream of tartar and I have not had to use any with great results. 🙂 If you experiment, please let me know how you like this recipe I’d love to know if that helps. Reply

      Hi Doreen, I recommend using unsalted because each stick of salted butter has 1/4 tsp salt so you would be tripling the salt in the recipe by using salted butter. I hope it turns out for you! Reply

    I’ve made this about 5-6 times now and I always use pasteurized egg whites just because I’m paranoid Lol
    Anyway, I still heat it and follow all the same directions as regular egg whites. Every time I end up having to chill it after the butter is added and the. Rewhip in order for it to firm back up. It always turns out great though and everyone loves it. I do refrigerate it if I won’t be eating them until the next day Reply

      So far I’ve added melted chocolate (about 5-6 tablespoons), rose extract (about 1-1(1/2) tsp), lavender extract (about 2-3 tablespoons), espresso (2 shots), lemon juice (3 tablespoons), vanilla extract (1 tablespoon), and orange juice (3 tablespoons) to this recipe. It holds up really well with added ingredients and I’ve been able to add all of these a little at a time until I’m happy with the flavor. As far as I know, you could probably add as much flavoring as you would like (within reason) without messing it up. Reply

    I love love love all the recipes that i have tried from your site. So good. I have made your vanilla cupcakes so many times! And your raspberry mousse is to die for!
    I have made this Swiss Buttercream about 5 times now and its really good. I do have a question though, is it possible to overwhip this type of buttercream? Or to overwork it? I noticed that as i started spreading it onto my cake it wasn’t as “white” as it was before. It was turning a yellow colour (almost looking like butter ) and it wasn’t as thick as it was before. I had refrigerated it after i made it. I took it out and i let it sit for 30 min then i whipped it again. It was still a little hard when i did that though. Could that be the problem? Reply

        Hi. I think the problem is, once my eggs have reached 160F, i beat the mixture for much longer than the 20 minutes in your instructions. It takes so long for my bowl to get to room temperature. If my bowl is not at room temperature after the 20 minutes do i stop beating and just let it cool to room temperature? Or should i not use the bowl of my stand mixer for that initial step and maybe transfer the mixture into the stand mixer just for the whipping stage? Reply

    I tried the recipe as written. Before adding butter to it, it turned into a shinny, sticky/gooey, white mess that couldn’t hold it’s shape no matter how long I beat it. I chilled it, nothing. I was using a hand beater yet I did beat it mercilessly. I regrouped and researched an answer. I did a small test batch out of my …frustrating results so far. I added butter to some and chilled for a good 20 minutes. It came together beautifully!!! It held up beautifully to liquid and gel coloring and piped great. I left out some for a couple days as a test and it is very stable still. Great recipe and thanks!!! Reply

    Hi, Natasha!
    I just made this, and it’s pretty runny.. I don’t know what happened. I don’t have a kitchen aid, but I mixed long enough for the egg whites to stiffen. After incorporating the butter, it ended up runny. I beat it for at least 20 minutes after incorporating all the butter, and it never got better. I put it in the fridge for a while and beat it again, and it whipped and stiffened up enough to pipe it. So I piped it onto my cupcakes, and now there’s literally liquid running down the cupcake paper. The icing is still in shape on top, but it basically looks like white water dripping down the sides. Also, if you tilt the cupcake, the icing slides off. I let the cupcakes cool over night. It’s not hot. It’s a little humid outside, but not raining. Any thoughts? Reply

          If you wanted to double it, I would suggest making a double batch since it would take a really long time to cool to room temp and would overwhelm most mixers. Reply

    I made the perfect vanilla cupcakes (which were amazing) and decided to try this recipe for the frosting. I’m very much a beginner and this was a little intimidating with the double boiling to 160 degrees and cooling down to the right temperature. However, I managed to get through it on the first try and just used normal food coloring to dye the frosting and this was so delicious! I feel so amazing that I accomplished it. I would just cut this recipe in half. I threw away a lot of frosting. The regular cupcake recipe made almost 50 mini cupcakes and half this recipe would have been plenty to frost them. So delicious though! Reply

    Hi, we made this recipe for cupcakes last night and it came out exactly as shown. We tried a cupcake each and it tasted airy and amazing. However, we had a couple left over after taking them to work and tried them again this evening and they were, eh… They tasted like slightly sweet butter. They looked exactly as we piped the night before but they tasted like whipped butter. Any idea what could’ve happened? They were made yesterday evening, stored in a cupcake container out of the fridge in a house at 65 degrees overnight and then set out for the day at work. I thought it was okay to not refrigerate this buttercream for that length of time. Many thanks for any insight you might have on this. Reply

    • Natashas Kitchen
      January 2, 2019

      Hi Julia, I imagine that may be the culprit. From what I have read, there are mixed thoughts about leaving it out vs refrigerating. The majority of sources I have found said it can be left overnight at room temperature. If you can refrigerate, that is probably the safest route and then let it come to room temperature before serving. I bet it would be easier to transport if it is chilled since the frosting firms up and is more stable for transport Reply

    Please help! This is my third try and im wasting so many ingredients and im out of them now. As soon as i add the butter the beautiful stiff peaks go to soup. I made sure it was not warm at all and ive wiped all tools with lemon first. Ive just put it in the fridge hoping for a miracle but it is marshmallow soup. Reply

    • Natashas Kitchen
      December 25, 2018

      Hi Missy, is it very humid in your house? I haven’t heard of humidity being an issue, but I suppose it’s possible. I would suggest trying with the AC running to decrease humidity somewhat. Usually, if you are getting “soup”, it is due to either not allowing the egg whites to cool completely to room temperature before adding butter. If the meringue is warm at all, it will take longer to beat the frosting for it to reach the correct consistency. I would suggest beating it a few minutes longer next time before refrigerating and if refrigerating, do that for no longer than 20-30 minutes and then beat again. Reply

    • Marcie
      December 28, 2018

      I’m curios as to why you heat the sugar and egg whites to 160°? Most Swiss Meringue Buttercreams only require a temp of 115 -140… This may be why so many are struggling with the “soupy” phase. Reply

    • Alycia Brown
      January 4, 2019

      Hi Missy, I had this issue too. A few tips. Put your mixing bowl and whisk in the fridge before use. When I add the butter if the bowl is warm I get a frozen item and then put it on the bowl to help cool it. My mixture goes soupy also but I also keep mixing until the end. It eventually comes together. Once all the butter is added and has been mixing for a few minutes, I like to stop it and scrape the sides and bottom and then continue. Honestly after doing that it starts to firm up. I’ve done that now 4xs in a row each being successful and I’m making another batch tonight. Reply

      I also had to fish out some yolk 🙁 I even break each egg separately to avoid this but didn’t notice until after I incorporated that egg.

    Thanks for this recipe! I was trying a mirror cake for the first time, and wanted something not too sweet to go under the glaze. The frosting was easy to make, though I think my butter was too soft, as it wasn’t as stiff as I would have liked after mixing. Half an hour in the fridge firmed it up nicely, though. I was able to frost a three layer cake with a decent amount of frosting. I’m not sure this has completely turned me off American buttercream, but it IS delicious, especially as I subbed out 1/4 tsp of almond extract for 1/4 tsp of the vanilla. It doesn’t taste overly buttery, or not sweet enough; it’s exactly what I was looking for. Reply

    • Natashas Kitchen
      December 15, 2018

      Hi Kristi! Are you changing any steps in the recipe? Two hours seems excessive. Does it seem like it is taking the cream longer to form stiff peaks? Also, your classic Kitchen aid, is it fitted with the correct sized whisk to help with even mixing and micing all parts of the mixture within the bowl? Reply

      • Kristi
        December 16, 2018

        I use the whisk that comes with the KitchenAid so I believe it’s the correct one. I follow the directions and read each time as I’m dling the recipe. I think the peaks in getting are more soft than stiff. And it takes a long time for the bowl to get to room temperature. But I keep the sugar and egg whites on a Bain Marie while constantly stirring until I don’t feel any grains in the mixture. Reply

        • Natasha
          December 17, 2018

          Hi Kristi, it could also be due to using a smaller bowl – mine is a 6Qt stand mixer so the bigger bowl and greater surface area allows it to cool a little faster. Reply

    This Swiss Meringue Buttercream Icing is so gooooood. Ran into one problem. And it has happened with every Swiss Meringue Buttercream recipe that I have tried. Every time I add the butter it becomes loose and won’t come back together no matter how long I beat it (And yes I make sure it is completely room temp. before adding the butter). My solution is to place it in the refrigerator until it firms up then whip it with the paddle attachment and it beat-up. It comes out perfectly.

    If your experience is anything like mine, you might find that it takes a REALLY long time for the bowl to reach room temperature. The second time I made this recipe, I put the bowl of egg whites and sugar in an ice bath and kept stirring it after melting sugar step. It cut a lot of time off and the result was better than my first try. Though I was too impatient the first time and didn’t wait until it was room temp so my butter melted too much while adding it to the meringue. I hope this helps someone out there! Reply

        Hey there Vicky, This is usually due to adding the butter while the meringue is still warm (make sure it is completely at room temperature) or adding partially melted butter. This can be remedied usually by cooling the frosting for a bit and continuing to beat it. Once the frosting has formed, it is perfectly safe to pipe the frosting and refrigerate it afterward. It is a stable and sturdy frosting and it won’t fall apart 🙂 Reply

    Hi Natasha!
    Made this buttercream last week and it was beautiful until I added food colouring. I set aside part of the batch to stay white and then dyed the other using a concentrated food gel. The mix went from smooth and silky to instantly curdled. I found that dyed batch had more of a gummy taste and would leave your mouth with a bit of a film afterwards. Not a complaint, just letting everyone know how food colouring went for me. Reply

    Hi Natasha,
    I have used this SMB before and it’s now my go to whenever I need to ice or fill a cake. I am now making a 3 x 10inch layer Engagement cake for my son and am using the buttercream as one of the fillings and to semi-naked ice the cake. Will it be ok if I double or even triple the ingredients to make the amount I need? And by the way,this is the best SWB by far! Reply

      Hi Charlie! I don’t see why not! If you have a large enough mixer it should work. Otherwise I recommend making it in batches. That cake sounds like it will be gorgeous! We would love to see it!

      October 23, 2018

      Hi Jade, I have used it to generously frost this 2-layer 9-inch cake so I think it could work well to frost a 3-layer cake if you are less generous with every later. Here is the cake we made. Reply

    Hi, Natasha,

      Hi! If it is runny and not pipe-able, the easiest fix is to beat the swiss meringue buttercream frosting a few minutes longer. It could be that the mixture did not cool completely to room temperature before adding butter, but it can be fixed with longer beating. I hope this helps. Reply

      • Summe
        October 21, 2018

        I had the same problem. I beat it for 45 minutes with a hand mixer and it ended up being a total flop, unfortunately. I think the hand mixer’s strength is the main issue, but the other thought was that there was fat remaining in the bowl in spite of washing it thoroughly. Looks like it’s time for an upright 🙂 Reply

        • Natasha
          October 21, 2018

          I think it may be either of those things and yes an upright mixer definitely helps with the mixing time on this one since it whips more effectively. Reply

          I had the same thing happen right before a birthday party. It would not solidify. Just on a hunch, I refrigerated it while I took my shower. When I came back to it and started whipping it, it fluffed up beautifully and the cake was saved! So many compliments on the icing!

          So, maybe try refrigerating? Thanks for a great recipe. Reply

    September 23, 2018

    Thank you Natasha! This was absolutely amazing! Made this for a 1st birthday party cake and this is now my go to buttercream. I truly appreciate the easy step by step instructions and pictures.

    it absolutely held up really well in our humid and hot weather. Cake was at room temperature at about 80 degrees for over 5 hours and the buttercream was light, fluffy and not too sweet. Almost like whipped cream. It was definitely a huge hit!

    I would suggest to double up on the recipe, if possible. Its easy to freeze leftovers and to defrost for a couple hours. Just leave it on the kitchen counter right before baking your next batch of cupcakes.

    It’s been quite a journey trying to find the perfect buttercream. I’m now looking forward to experimenting with different flavors like fruits and chocolate. Thanks again! Reply

      Oh man! I really fudged this up. By the time my egg/sugar mixture reached the correct temperature it was similar to a marshmallow consistency (it was delicious). I kept going and ended up with some really yummy (not very fluffy) icing- only about 2 cups total. I am going to buy a new thermometer and try again. Have you heard of this problem before? Reply

      • Natashas Kitchen
        September 28, 2018

        Hi Sam. Are you using a high powered stand mixer with whisk attachment? Also, did you place the egg whites and sugar on the water bath as directed? If you beat raw egg whites without sugar, it tends to look like marshmallow fluff. Did you possibly omit the sugar? Was anything else changed or modified either in process or ingredients in the recipe? Reply

      • Cheryl
        September 28, 2018

        Sam, I never heated up my egg whites. I used Pasteurized Egg Whites and they worked great. The brand I use is called, All Whites. I also use them for whipping up a really good homemade Angel Food Cake. I’ve never had a problem with them. I just whipped them for quite some time. And when I started adding the butter, it scared the wits out of me because it started getting soupy and I wasn’t sure it was going to work. But once I added all the butter and whipped it for about 20 minutes…wow…it was perfect. Just thought I’d pass that info along to you. 🙂 Good luck. Reply

  • September 16, 2018

    Hi Natash, SMB cream is great made it successfully on my first attemp however, mine is creamy in colour (off white) not white as yours. Do you have an answer to this.

        • Natashas Kitchen
          September 22, 2018

          That could be the case, some butters are more yellow in color so maybe try switching to a different butter. I’ve tried organic unsalted by Simple truth brand and the longer sticks from Costco by Kirkland signature unsalted butter and both were very white in color. Reply

        • Kylie
          November 10, 2018

          Try Lurpak and let it whip for a little longer as that also helps whiten the butter. Our Australian butter is so much more yellow sadly. Reply

    Finally, a swiss buttercream that is absolutely PERFECT! Not so sweet, not too buttery tasting, but exactly what I was looking for. I was starting to give up on this type of frosting as all the ones I was trying out tasted too sweet or too much like butter.

    Natasha, I was so disappointed when I made this, it was soupy like some others said. I kept beating it and it never thickened. I put this in my fridge over night. When I took it out in the morning it never thickened when I rewhipped it. I started all over again and this time I tried to pay close attention and made sure I tried some tricks others mentioned. I put the bowl in a shallow pan with ice in it and kept stirring it till it cooled down. Then I whipped it up and finished and was very excited to see it whipped up. I only used 1.5 tsp of vanilla instead. Thanks so much for the recipe and the ideas from everyone. Reply

    Do you think your recipe is suitable to cover the cake?
    And thank you for the gram measurements.
    In Japan we don’t really have cups, more like spoons, but I prefer grams to be exact.

    So I made a double batch of this, and my butter was too soft when I put it in so the SMBC was too soft. I chilled it and that fixed it.

    But here’s the thing: It doesn’t taste like and SMBC I’ve ever had. It still tastes like pure meringue and is very sweet. Can/Should I add more butter? What might happen if I do? Reply

    • Natasha
      September 8, 2018

      Hi Maya, you could add a little more butter, but it may start tasting more buttery. This combination of ingredients produced what we thought was the best balance – it also depends on what type of cake you put it on. If the cake is sweeter than the frosting – it will taste buttery. Reply

      September 7, 2018

      Hi Ester, to be extra sure, use a thermometer to make sure the whites/sugar reach 160˚F which is the safe temperature for egg whites without actually cooking them. 160˚F is the temperature at which salmonella bacteria is killed which is why I prefer this SMBC frosting over other meringue frostings. Reply

    September 7, 2018

    I’m making this recipe for the first time for cupcakes I’m bringing to a birthday party tomorrow. I noticed some of the comments said the frosting was runny after being in the fridge. So I was wondering, if I frost (pipe) the cupcakes tonight and put them in the fridge, will they fall apart? Reply

    • Natasha
      September 7, 2018

      Hi Nicole, I think they meant that the frosting wasn’t firming up. This is usually due to adding the butter while the meringue is still warm (make sure it is completely at room temperature), or adding partially melted butter. This can be remedied usually by cooling the frosting for a bit and continuing to beat it. Once the frosting has formed, it is perfectly safe to pipe the frosting and refrigerate it afterwards. It is a stable and sturdy frosting and it won’t fall apart 🙂 Reply

      September 6, 2018

      Hi Tamia, I would suggest testing that combination in advance (wedding cakes would make me nervous for experimenting). It should work fine to frost over a buttercream crumb coat and this frosting is freezer safe so it should be ok to freeze the finished cake. Reply

      Hi Jasmin, if it will be left out for a long time, I would experiment with refrigerating it as long as you can and then letting it come to room temperature over time during the wedding. It will take a couple hours for it to fully soften (more or less depending on the temperature of the location). Reply

    Omgoodness this recipe is so yummy! Thanks for sharing- such a good change from the usual butter cream frosting! It’s lighter, and so silky- and somehow feels like its a tad healthier since the egg whites take the place of all that shortening! This is a keeper for sure!
