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.

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.

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).

    Thank you, Natasha for this recipe! This is my first time doing a Swiss meringue buttercream. I did add a 1/4 cup of Hershey’s unsweetened chocolate powder and boy does it remind me of chocolate ice cream! it was that good😊. It took me a while only because I use a handheld mixer. Don’t have a stand mixer yet. I just kept beating/mixing until it finally came together. I’m looking forward to using this recipe again. Reply

    I’ve made this a few times now and it always comes out great. This past time it was a bit warm in the house and I don’t think I let the bowl completely cool before adding the butter. It went a little soupy so I followed the tips and refrigerated for 15 minutes then whipped it and it was perfection.

    I like my frosting a bit sweeter than this comes out, but I think that’s just my sweet tooth. Everyone else who tries it loves it. I might try more sugar in my next batch. Reply

    Followed this exactly and was going well until adding the butter. It became very thin and could not be used as frosting. The more I mixed it the worse it became. Reply

    • Natasha
      May 17, 2019

      Hi Cynthia, don’t give up! In most cases, that is fixable. That can happen if the butter is added before the meringue is fully at room temperature or if the butter is over-softened. I suggest refrigerating for 10-15 min then continuing to beat for a few minutes. It does look like it won’t come together but it will. I hope that helps! Reply

    Tried this recipe out to go with your chocolate cake recipe as I was looking for a chocolate recipes with a white icing, and since this is gonna be for a 4 year old, when I saw the words “not overly sweet” I was sold, any reason to lessen the sugar high the kids will already be in for the party. Anyhow, I do not have a stand mixer nor does my hand mixer have a paddle attachment so I thought I’d give it a try beforehand. I’m glad I did, and sad to say I will be looking for another icing recipe. This took me too long to do, practically all of my 1 year old’s nap time. It’s too much whisking for a hand blender. I ended up using 2 whisks hoping to get a faster result, it still took over 20 mins, stopping a couple of times to let my machines cool down and my arms rest. In the end I got the amazing gloss and a tiny bit of peak. All looked (and tasted) great, until I added the butter using the electric beaters (no paddle attachment). At first the meringue was eating up the butter really nicely. Then it just started to look to crumby. I put it back in the fridge, 1 y.o woke up so fed him lunch, then took it out of the fridge and It actually got more liquidy. I beated it some more, Looked slightly better, but still not presentation worthy. I’ll probably keep it, could maybe use it at least to ice in between the two cake layers. I’ll try beating it some more tomorrow. But maybe this crumby look is the effect of the beaters instead of the paddle? Just the same, I very much enjoyed licking down the spatulas during clean up. Tasted like very yummy and light vanilla ice cream.

    So, great recipe! But lost a star because it’s not fool-proof, lots of slight “mistakes” can happen that greatly affect the final product. And another star because it’s not simple enough for every and all kinds of bakers (in terms of expertise at least) – i.e. those who don’t have stand mixers and paddle attachments. Reply

      May 16, 2019

      Thank you for your honest feedback, Arantxa! If it is runny and not pipe-able and too runny, 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

        Hi! I have used this twice now. Its soooo good! The first time was for cupcakes. I had PLENTY for 2 dozen cupcakes and some left over. However, for a bigger cake, I was a little short. Has anyone doubled this exact recipe and is it just as good? I’m only asking because when I Google ‘large batch of smbc’, the recipes dont quite add up in measurments to this one. For example, the few I looked at had almost twice the amount of egg whites, but almost the same amount of sugar as this recipe. So if I double the sugar to 4cups, would that be too sweet? I know this is kind of a complicated question, haha. but I basically need a larger batch. Thank you Reply

        • Natashas Kitchen
          May 21, 2019

          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

        May 21, 2019

        Hi! Yes, I did refrigerate for quite some time and try to beat it some more, I did this maybe 3 times. I actually found that after refrigeration, there was some liquid in the bottom that had separated from the rest of the ingredients. Anyhow, I still slathered it all over the cake and it still tasted amazing. It was just a trial cake so for a “no special event” cake, we were all very happy to still eat it despite how it looked. I froze the leftover and will see if that does anything. Otherwise, I’ll just blame it on not having the paddle attachment. I’ll update when I do. Cheers! Reply

    All I have ever made was a normal American Buttercream because I was afraid to go outside that box. I finally went outside that box today and made your SMBC and I have to tell you – it is the most amazing, smooth, cloud-like, tasting frosting I have ever made. I followed your recipe exactly (weighing egg whites, sugar) with one exception. I did use carton egg whites. They were 100% egg whites, no additives. It came out like a dream. I have it in my fridge now because I didn’t need it tonight, was just wanting to see if I could do it. I am looking forward to seeing how it pipes because I do a lot of cupcake/cake decorating (very amateur I might add) but can’t wait to try and pipe something tomorrow. It is soooo much more delicious than my standard American buttercream. Reply

    I have always made “American Buttercream”, ie “sweetened shortening”! I was always envious of these silky smooth, just sweet enough frostings. Well, I found my new go to.
    At first, it was liquid-y and I thought I would just continue with my old stand by. I put it in the fridge and then rewhipped it. If I didn’t need it to decorate a cake, I would have eaten the whole bowl!!
    I did have to make a second batch. I bought egg whites in a carton end it came out good but just a little stiffer.
    Thanks for such a great recipe!
    Making another cake tomorrow for a graduation! Just need to figure out how to make some into chocolate frosting. Reply

      That’s so great Lisa! 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 am about to use your recipe for a rose-flavoured christening cake, but have just noticed in one of your responses that you suggest not using pre-cartoned egg-whites. What’s the reason for that please, because I hate having yolks lying around with a potential for waste. If I use the carton whites very fresh, would your opinion be any different? [ And do you suggest medium or large eggs?] Thank you! Reply

      • Natasha

    Help! My butter cream is like soup, I have followed previous comments of putting in the fridge then whipping it again but it is still like soup! How long shall I whip it for once it’s been in the fridge? Is there anyway of saving this!? Reply

    • Natashas Kitchen
      May 6, 2019

      Hi Lucy, if you are still 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

  • Agnes

    It tasted great but I did something wrong. It was too soft and grainy. Did I under whip it, or was it too warm when I put the butter in? Or maybe both. Reply

    • Natashas Kitchen
      May 4, 2019

      Hi Agnes, are you doing anything different in the process or maybe using a different tool (hand mixing versus using an electric stand mixer) – using the correct attachments? Not trying any substitutes such as egg whites in the carton? Was the mixing bowl completely at room temperature before adding butter? Most issues with texture are repairable with a little bit longer mixing. I hope that helps! Reply

      I read using a meringue to apply sprinkles to the outside of a cake is best. My reg buttercream frosting seems to set up too quick to add sprinkles to. If I made this, then froze the cake so I could flip it (I only want the sprinkles on the top) 1 will i be able to flip it without ruining the icing on the top?? 2 will it still allow sprinkles to stick?? Reply

      • Natasha
        May 1, 2019

        Hi Barb, I’m honestly not sure what you mean by flipping the cake – do you mean the bare cake layers or a frosted cake? You would want to bring this frosting to room temperature for the sprinkles to adhere. They would not adhere to this in its frozen form. Reply

    Yay! The heaven’s opened up when this recipe worked on the first try! Your instructions were spot on (except for the minutes it took to come to temp – for me much longer), and it felt like that bowl would never cool, but finally it did. At first the mixture was thin, but following your instructions in some of the comments I kept the mixer running and it came together beautifully. I pulled out half for another use and put some lemon curd in the other half and it still held it’s consistency. I plan to pipe it into some lemon macarons! Thank you tons!!! Reply

      Hi Frauke, 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. I would add the at the very end. Reply

      Hi Nancy, 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

      Hi Amanda, I haven’t tested with carton whites but I have heard readers report both (that it works and others day that it doesn’t), so it may depend on the brand and whether or not there are any additives? One reader wrote: “I did try with the egg whites from a carton and it didn’t work. I started again, this time using egg whites from regular eggs and it worked beautifully.” If you test it out, please let me know how it goes. Reply

        • Natashas Kitchen
          April 19, 2019

          Hi Lisa, usually if you just continue beating it for another 2 to 3 minutes, it will thicken. You may run into 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

    This is an excellent Swiss buttercream recipe. I followed your recipe exactly and it worked wonderfully. It was lighter than most, which I very much appreciate. A lot of Swiss buttercreams often taste like sweetened butter, but this did not.

    The only thing I would recommend is to perhaps not make the last beating time of 3 minutes a definitive thing. I found my buttercream was perfectly creamy without the additional three minutes. However, I did beat it for 2 more minutes, which I feel put too much into air into it so that it no longer had that very smooth appearance and instead looked like over-whipped cream. I know many have had the opposite problem, but that is easily solved by checking the temperature of your ingredients. I continuously scanned the temperature of my meringue mix and did not start mixing it with the butter until it reached 73 F. I also whipped my butter and it was at 62 F. Ensuring the temperature is actually room temperature will probably help a lot of people with this icing.

    Thank you again for the recipe. It is really a very lovely buttercream. Reply

    Hi
    I made this 3 times in a row, it comes out perfect. Stiff and firm but while I’m working with it (like crumb coating) it starts getting runny. For the final coat it’s not even firm enough to achieve sharp edges. What am I doing wrong?? Is there something I’m missing? Is it supposed to be kept cold while waiting for the crumb coat to get stuff? Reply

    • Natashas Kitchen
      April 13, 2019

      Hi IRene, 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

    Help!! I’ve just made a batch and must have not scraped the bowl well enough while melting the sugar into egg whites because I ended up with a gritty buttercream.

    • Natashas Kitchen
      April 12, 2019

      Hi Danielle, the liquid egg whites may have been the culprit. Are you doing anything else different in the process or maybe using a different tool (hand mixing versus using an electric stand mixer) – using the correct attachments? Not trying an substitutes such as egg whites in the carton? Was the mixing bowl completely at room temperature before adding butter? Most issues with texture are repairable with a little bit longer mixing. I hope that helps! Reply

      • Danielle
        April 12, 2019

        I did use egg whites from the carton because they are pasteurized I was hoping for some peace of mind. That is the only difference.

        Is there any way to save this batch? Maybe heating up the buttercream, refrigerating, then mixing it all again?? Reply

        • Natasha
          April 12, 2019

          Hi Danielle, do the egg whites have any additional additives? You might try refrigerating 10 minutes and then beat again – most often, it is due to the mixture being too warm to form. I would not reheat it, but cooling might work. Reply

            April 14, 2019

            Hi Natasha. I use pasteurized carton egg whites all the time with no problem. All whites brand. I have heard that if there are any undisolved sugar crystals left, it can reseed the batch. Also heard that if the temp gets too high, it is especially vulnerable to that.
            I actually use the microwave slowly until 160 degrees. Very fast, then put in freezer until cool. But then again, I beat the BUTTER until fluffy, then add cooled egg/sugar mixture in 2batches. No Meringue! It is firm at this point. Easy, fast, fluffy and delicious!
            I did have a question. Do you ever add cookie butter or peanut butter to your SMBC? Thank you!

          • Natasha

    Hi Natasha!
    I tried the buttercream recipe, the taste was delicious but it did not get thick as in the picture. I made a mistake when adding the butter, I forgot to switch to paddle attachment. Only when it was all in I did remember about it and did the switch and kept beating for 10 more minutes, but it was more like a creamy consistency. I then transfer to the refrigerator and it got a little better. Do you think it was because of my attachment mistake or maybe the room temperature/humidity may affect? I live in Panama and our weather is very hot and humid.
    Thank you in advance! Reply

    • Natasha
      April 7, 2019

      Hi Yisel, both the attachment and the humidity or room temperature can affect the outcome. If it is very hot and humid, the mixture will take significantly longer to cool down and form into the right consistency. I would suggest refrigerator for 10 minutes and then continuing to beat with the paddle attachment which may help to get it to the right temperature faster. Reply

    Hi Natasha, my frosting ‘ran’ completely… my egg whites were perfectly beaten and thick, after I added butter (it was not warm) it became lumpy and I have been beating it for almost an hour now. The volume decreased three times in size…. Do I keep beating or is it over beaten? Reply

      if you are getting “soup”, it is due to either not allowing the egg whites to cool completely to room temperature before adding butter.

    The last time I made SMBC it became soup because I didn’t wait long enough for it to cool, so this time, I had a moment of panic when it got a bit loose as I began adding the butter. I put it in the fridge for a little while, then added the rest of the butter and whipped it on high speed, and I swear whipping it on high speed was like a magic trick! It got soooo thick and luscious! I was so happy :’)
    It looks kinda like whipped cream that was whipped a little too much, but that’s okay because the texture when you bite into it is absolutely gorgeous and smooth.
    Maybe it started getting soupy because I used pasteurized egg whites? Either way, it worked out well anyway, and something that’s great about this frosting (I used it for a batch of lemon poppy seed cupcakes) is that it’s so rich, you really only need to eat one cupcake to be satisfied 🙂 Reply

    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?

      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

        Hi Natasha! Unfortunately I don’t have a stand mixer but I do have a hand mixer. I really want to try your recipe for my brother’s engagement party cake. How would my directions differ with the hand mixer? Reply

          April 12, 2019

          Hi Jessica, 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

    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

    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

      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

    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

        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

    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

      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

    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

      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.

      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

      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

      Hi Susan, I haven’t had that happen, I’m wondering if that ould be the culprit. Are you letting it cool completely before adding the butter? Ay other changes made to alter the recipe? Reply

        No changes made whatsoever. I tried to follow the recipe to a T. Waited for the whites to coll completely. Is it possible I did t hold the whites over the water long enough? They were stiff peaks when it was done beating. Not sure what happened. Maybe I’ll be brave enough to try it again one day 😏 Reply

      January 24, 2019

      Hi Julianna! I haven’t tried making this chocolate, but From my research, chocolate is always added at the end. I would probably start with 8-9 semisweet chocolate, melted and slightly cooled and whip it in at the end. Reply

    Hi Natasha!
    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

        January 23, 2019

        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

      Hi Michele, 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. Reply

    I am currently making this icing. After removing from the heat and beating for 13 mintues I had the most beautiful, stiff glossy, icing, added the margarine and it’s become soup. I’m going to see after beating it what happens and will post results. The bowl is cool and the egg whites as well. Reply

    • Natashas Kitchen
      January 20, 2019

      Hi Vicki! 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

          I tried this today & it worked beautifully. It was a little soupy after I added the butter, but I just let it keep whipping & it was great. I do have 2 questions.
          Is it possible to reduce the sugar by 1/2 cup with the same results?
          And is it necessary to switch to the paddle attachment? Reply

      Pop it in the freezer for about 20 minutes and the beat it with the whisk attachment for 5-8 minutes 🙂

    Wow! I’ve just made this today for the first time after stumbling across your blog! The icing is amazing. So thick and glossy and easy to work with – I wanted to make an ombré cake and everyone recommend this type of icing! Made a trial batch cake today with this, and now cannot wait to ice my daughters 3rd birthday cake with it next weekend! My icing was way too runny after the final step but 30 minutes in the fridge, 5 more minutes of beating and it was perfect – I think my meringue was still too warm when I added the butter! I can’t wait to try your other recipes now! Reply

    Hands down the best, most silky delicious frosting.( I despise American buttercream). Cannot stop licking my bowl. This may even beat my mommas frosting recipe, which has been my go-to for years! Quick question though; once I’ve decorated my cake can I freeze it and expect it to still be delicious? Reply

      January 18, 2019

      Hi Anna, I’m so happy you enjoyed that. Thank you for sharing that with us! I have only tried refrigerating this type of buttercream but from my research, it should be ok to freeze. I haven’t tried freezing an entire cake but I think it can be done since this frosting is freezer safe. I hope that helps! Reply

    Can I make half of this recipe?
    Also.. which piping tip have you used to create those beautiful swirls on the cupcake? Is it Wilton 1M tip? Reply

    • Natashas Kitchen
      January 18, 2019

      Hi Sandy! We used that Wilton 1M for the frosting swirl. One of our readers wrote, ” I’ve made this recipe twice and it turned out so good. I even halved it for 12 cupcakes and it was the exact amount to pipe them beautifully (exact measurements).” Hope this helps. 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

          Another site said do not try to make the icing without a Kitchen Aid mixer a regular mixer’s motor is not strong enough however what I learned is to put it in the refrigerator then whip again but I have a KitchenAid mixermi Mine never comes back together no matter how long I mix I mixed it over 30 minutes it stayed soupy so I put it in the refrigfor about 20 minutes or so and then it whipped up perfectly delicious Reply

    • Natashas Kitchen
      January 6, 2019

      That may be enough, Rachel, possibly more if you are looking to generously frost. I used this recipe to frost this two-layer nine-inch cake so I think it could work well to frost 2 short cakes if you are less generous with every later. Reply

          January 7, 2019

          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
