My entire family was smitten with this prune honey cake; especially Mom. She had 2 slices ;). This cake is traditionally called Chernosliv (black prune cake). I’ve been developing the recipe for months and was really close to throwing in the towel because my initial cake layers looked more like bowls rather than cakes.
I felt this cake was worth-while so I stubbornly continued on with my experiments. Now it’s finally perfect! This prune honey cake rose beautifully and was stunningly tall. The layers are fluffy, moist, creamy, and studded with sweet prunes.
P.S. There’s a very cool baking soda/honey chemical reaction in this cake. Like “kids come check this out” type of cool!
Ingredients for the Prune Honey Cake Layers:
6 large eggs, room temp
1 cup white granulated sugar
2 cups unbleached all-purpose flour *measured correctly
5 Tbsp honey
2 tsp baking soda
Ingredients For the Frosting:
32 oz sour cream
2 cups powdered sugar
1 cup heavy whipping cream
Fillings/Toppings/Decor:
1 1/2 cups chopped prunes
Melting Chocolate or Chocolate chips to melt for decor
Chocolate block for shavings
How to Make the honey cake layers:
Butter and line the bottoms of 2 (9-inch cake pans) with parchment paper. Preheat the Oven to 325˚F.
1. Using your electric stand mixer, beat 6 large eggs with 1 cup sugar 5 minutes on high-speed.
2. {Here’s the cool chemical reaction part: did you know honey activates baking soda?} Heat 5 Tbsp honey in a saucepan over medium heat until it is very hot, but not boiling (about 125˚F), stirring often.
Just as soon as you see faint bubbling on the edges, use a spoon to stir in the 2 tsp baking soda into the honey stirring continuously until your mixture turns a yellow/light caramel color (about 30-45 seconds seconds) and immediately remove from heat. It will continue to cook even after you remove from heat. Continue stirring until you’re finished adding it to the egg mixture.
This is what it looks like by the time you are ready to spoon it into the egg mixture. You don’t want it darker than this and it happens quick so don’t step away from it!
3. With the mixture on high speed, add hot honey to the egg mixture about 1 Tbsp at a time so you don’t cook your egg mixture. Also, don’t wait for your honey mixture to cool down or it will harden and you won’t be able to blend it into your egg mixture.
See that honey on the edges of the bowl? That’s pretty much candy. It’s expected. You won’t be able to scrape it down into the bowl, but don’t worry, it washes off easily.
4. Reduce mixer speed to med/low and blend in flour 1 cup at a time. Use a spatula to scrape down the mixing bowl to make sure the flour is well blended.
5. Just as soon as the flour is well incorporated, divide into two prepared baking pans and bake at 325° for 25-28 minutes or until the cake is golden brown and a toothpick comes out clean.
Once they are cool enough to handle, remove from the pans and transfer to a wire rack to cool completely.
To make the Honey Cake frosting:
1. Beat the heavy cream until stiff and spreadable (1-2 min on high speed).
2. In a separate bowl, whisk together 32 oz sour cream with 2 cups powdered sugar. Fold the whipped cream into the sour cream and you have your frosting. Refrigerate until ready to use.
Honey Cake Assembly:
1. Once your cake is completely cooled to room temp, slice your cake layers in half and keep the halves stacked until ready to assemble so your cake doesn’t dry out.
2. Order of layers (assemble the cake on your serving platter).
(A) First cake layer (B) enough frosting to cover the layer (C) 1/3 of your chopped prunes (D) thin layer of frosting on the bottom of the next cake layer (like putting mayo on both sides of bread for a sandwich), then repeat steps (A-D). Frost the outside of the cake and sides then decorate with piped strips of melted chocolate, chocolate shavings and more prunes. Prunes prunes the magical fruit, the more you eat, the more you,… did I really just go there? Sorry about that. Lol. Anyway, I think the song was meant for beans. oh nevermind! :-O.
3. I melted some chocolate and piped it on over the top in a checkerboard fashion, then put some horizontal lines on it for extra awesomeness.
Come to Mama.
P.P.S. This cake is best eaten the next day after the layers and prunes have gotten a chance to soften up with the velvety sour cream frosting.

What happens if I use bleached flour?
Nothing. You can use bleached flour. I always just write what I use exactly.
Hey Natasha,
If I were to add some nuts into this cake, what would be some of your suggestions on which ones I should add???
Hi Yulia, I haven’ tried it but I do think it prunes and walnuts would taste good together. Even if you just decorated the top with walnuts it would probably taste great with the prunes.
Now it’s my hubby favorite one!!! 😉
I’m glad he likes it 😀.
Hi Natasha!
So I made this cake today for my daughters birthday and it’s chilling in the fridge. It looks beautiful, just like yours😁
I did something different though and I’m curious to see how it will affect the flavor of the cake… I soaked the cut prunes in sweet red wine!!! I don’t think you can go wrong there, but we will see I guess! 🍷🍰 after the prunes soaked, the wine was more of a syrup and there’s wasn’t so much of it, so I just spread it evenly on the korzhi. It won’t soak the layers, but it should add just a little kick to the cake!
Im so excited to try it! As soon as I do try it I’ll let you know how that worked….
Also, thanks for all the wonderful recipes! You are so good at what you do! And oh so enthusiastic! ! Your sense of humor and happiness rubs off on me 😉😘
Your blog is the first one I go to when it comes to finding a recipe or cooking something! Oh, and my little nieces and nephews (and my kiddos of course) love watching your videos! Lol its like мультики for them! 😂
Anyways! Keep up the good work, good luck, and GOD BLESS!!
Awww your comment… the best! I’m all smiles :). Happy Birthday to your daughter! Thank you so much for taking the time to write in. I love that the littles in your family enjoy the videos. That’s so adorable. Can’t stop smiling over here. Thank you. Your comment blessed me so much. And let me know how the prunes taste soaked in wine. It does sound like a great idea! 🙂
This cake is always must be on our table during any winter occasions such as birthdays and Christmas. I have made this cake for Christmas Eve and not only me who loved it but everyone else as well. From 5 times making the same cake, the last one was one of the best because finally, I have made it with a Kitchen Aid Stand Mixer 🙂 🙂 :). Making this cake tonight again for my Nephew’s birthday… Thank you and once again Thank you for this recipe and step by step instruction.
Because of You, know I am in love with baking. I love baking and it is not that hard as I though it would be. I am improvising new recipes based on basic techniques that I have learned from you. Thank you once again.
I have all kinds of fuzzy feelings reading your comment. Thank you so much for sharing that with me :). And I’m so happy you love this cake! It’s one of my favorites also 🙂
Hi Natasha
My husband and i we love this cake!!!
I probably made it like five times.lol
Thank you for sharing your fantastic review!! 🙂
How far in advance can this cake be made? I’d like to make it three days in advance, because I work the two days before the event and I’ll be short on time then. Do you think that will work?
It looks really good, thanks for posting.
Yes, it would work a few days in advance, just cover and refrigerate until ready to serve. 🙂
Hi! Can I use cool whip instead of heavy cream? Thank you:)
I haven’t tried that so I’m not sure how it would affect the cream flavor or texture. I imagine it would work, but without trying it, I can’t say for sure.
Hi! I want to try this cake but it looks a bit dry. I know you said to let it sit for a day to moisten up.. Will it really get moist enough? If not, what could you saturate it with? Thank you!!!:)
Hi Irina, It really isn’t a dry cake. The cake layers absorb some of the frosting and it’s great without needing any extra syrup. 🙂
Hi Natasha! I’ve been wanting to make this cake for a long time now! I do have a question though: Have you tried using Canadian flour and how was your results with it? Thank you! Would like to bake this cake for my daughter’s birthday☺ thank you for a great blog!
I haven’t tried using Canadian flour for this one so I’m not sure how it would affect the results. I do like Canadian flour for baking but I don’t use it normally since it’s not readily available for everyone. Sorry I can’t be more helpful.
No problem, and thank you so much for quick response!
Is there any way I can make this cake on a cookie sheet, have a huge cake? Double the recipe, to have 4 layers? Going to have a lot of people over and don’t want to make two cakes.
Olga, I haven’t experimented that way so can’t tell you exact baking time. It sounds like it could work. If you try it, let me know what you end up doing :).
Wow! Natasha, I enjoy your website so much! So glad I found out about it. The website is so well built and organized , the order and pictures make it so easy to follow and remember . The recipes are great . I don’t like to cook, honestly )) but I finaly found the perfect “book” )) I ve already done cheesecake and deruni with your help ;);) my family loved it . Thank you thank you thank you! You are amazing !
Hello and thank you for writing in! I’m so happy you are enjoying the recipes and my blog. I think you will love the new design (coming soon) even more as we focused on making it more user-friendly. Thanks again!
What a great cake! I made it twice in the last 2 weeks and both times it turned out absolutely amazing! Thank you, Natasha, for such a great & detailed recipe!
I’m so happy to hear that! Thank YOU for the awesome review!
I really like this cake! My mom used to make this cake in many different ways! And now I am able to make it! It’s actually pretty easy and turned out all so good, except that the cream wasn’t as puffy! But it was a good combination with the cake! Thank you so much for making it a ton easier with the pictures and step by step process! God bless you! 🙂
Thank you for the great review Nita and you are very welcome :).
oh this cake. Advice for everyone use the same sour cream as Natasha’s used if you don’t want to be embarrassed of your cake. I used different sour cream and cake’s frosting wasn’t good (didn’t matter how much heavy whipped cream i have putted to it). This cake is one of my favorite cakes to make. I always make this cake two days in advance. Because the longer this cake stays in fridge the tastier it is…
Thank you for this recipe. This cake is extremely good.
Thanks Ziz’ka! There are sour creams like the Canadian one that don’t work well for this frosting since they are too liquidy. I’m so glad you still liked the cake 🙂
Hello Natasha. U said y melt chocolate and put it over the cake. How dou melt the chocolate chips ? I do it on stove only since I don’t use microwave in my house do I need to add a little bit of butter when I melt or no? Any advice? And I tried this cake before it is amazing and I love it how I can do it before hand and it sits in fridge and is amazing 2 days latter.
You could do it on the stovetop but be super careful that it doesn’t overheat or else it will dry out and become crumbly.Remove it as soon as it starts to melt and stir constantly. If it needs a little more heat, you could always put it back on but you can’t undo overcooked chocolate. When I make ganache, I use heavy whipping cream and chocolate chips. I think a tiny bit of butter or cream would help to keep it from getting too dry.
Would u b able to share the per portions on the heavy cream and chocolate if u don’t mind me asking, I want to try. I never had luck with melted chocolate
Absolutely! Here is the recipe: https://natashaskitchen.com/2014/03/26/perfect-chocolate-ganache-how-to-glaze-a-cake/. You would probably want to cut the recipe down for how much you need 🙂
Hi Natasha! I made this cake two days ago. I think I let the honey to boil, I didn’t expect it to boil so fast, so the color of the soda mixture was darker than yellow. May be it was the reason the cakes didn’t rise. I also used 10′ pans, so it’s an additional reason that I’ve got pretty flat cakes. But I still managed to cut them into halves. All in all the cake tastes great. The only change that I would make in the future is to reduce the amount of sugar, especially in the frosting. Way too sweet, to my taste. Thank you again, I;m also in love with prunes. 🙂
You definitely have to keep an eye on the soda mixture and I’m not sure if that would be the reason for it not rising; possibly? putting in a 10 inch pin would definitely be a reason for it not rising as much. A narrower pan will produce a taller cake. I am a big fan of the prunes also. Aren’t they great after letting the cake sit and moisten them up?
Fantastic web site ! One comment with respect to the baking soda being activated by honey. Baking soda is activated is either by heat or by acid (hence the baking powder = soda + dry acid). One of the commenters below was puzzled about cake not rising – the possible reason can be exactly the fact that all the leavening which was created by soda activated while heated by hot honey, had left soda without leavening power ?
Love the recipes and attention to detail. Really good web site, thank you for making it !
Thanks Natalia, there could be several different factors why it didn’t rise. I don’t think it was heating the honey with baking soda since I’ve tested it this way and it rose really well for me and was super fluffy. You’re so welcome! I’m glad you are enjoying the site 🙂
Sponge not rising is is most likely due the length of duration of the exposure of soda to heat: if left on the stove too long, the leavening power of soda gets greatly diminished.
I tried the 4 eggs with 1.5 cups of flour – works really well, and only 1 tsp of soda, but I also added 1/4 tsp cream of tartar (which is acid) to the egg whites. Acid stabilizes the whites and acts as an activator to the soda, making the batter error proof for raising.
Also, the following combination of two layers of icing works really well with this honey cake:
1. heat 2 egg yolks with 1/4 cup of milk over a double boiler pot. Constantly whisking add 3/4 can of boiled condensed milk (boiled ahead in the can, completely covered by water for 2 hours, then cooled), until eggs thicken. Cool the mixture down and mix (using electric mixer) with a 1/2 lb of unsalted butter. Set aside
2. Mix a tub (454g) off full fat sour cream with a 1/4 cup of sugar
Cut the cake into 3 layers, spreading 1st icing type and then 2d icing type over each layer, all the way to the top. Sprinkle the cake with graham cookie crumbs and let stand for 1 hours in the fridge.
Yes, you definitely don’t want to leave it on the stove too long. Thanks for sharing! 🙂
Could you spread a thin layer of plum butter on each layer with the frosting instead of the prunes?
Yes! That would be delicious as well 🙂 If you share a picture online somewhere, do tag me #natashaskitchen so I could see it. I love your idea!
I’ve been looking for this honey cake recipe. Am so excited, will make it for my son’s birthday! Thank you so much!!! I love it with Del Monte sliced peaches or fruit cocktail (instead of prunes). For frosting I use sour cream sweetened with condensed milk and a little bit of vanilla-sugar powder! Try it, you’ll love it! 🙂
Oooh that does sound really really good for frosting. What amounts did you use for sour cream and condensed milk? Also, was it just uncooked, canned sweetened condensed milk?
I was wondering if I make this cake about 24 hours before serving would it still be the same great taste or its better not to make it so early?
Yelena, cake will actually taste better when made 24 hours in advance. This way, the prunes had time to soften and the cake will be more moist. I hope you’ll love it :).
3 packs 20% sour cream (probably 3 16oz tub sour cream); 1-2 tsp. vanilla-sugar powder; condensed milk (uncooked, canned sweetened). Add condensed milk to your preference, I don’t like very sweet frosting so most of the time I use only 1/2 cup but others prefer to use the whole can. I start with 1 tsp. vanilla-sugar powder then I just add more if I want a richer vanilla flavor although my boys love the frosting with just a hint of vanilla in it – they say it tastes like vanilla ice cream! 🙂 Oh and I use a regular spoon to gently mix the ingredients so it doesn’t get runny. 🙂
Thank you so much for sharing that! 🙂
I made this cake today, I used 3 layers for the cake and made the 4th layer into cake crumbs (I used to decorate the sides of the cake). Will bring it to our family get-together tomorrow, my boys ate the leftover cake crumbs and asked me to make this cake again and again!:D I bought the wrong whipping cream so I ended up using only sour cream + vanilla-sugar powder (that I sweetened with condensed milk). Thank you so much for sharing this great recipe Natasha!!! God bless!
I’m so happy you all of the cake. Thank you so much for an awesome review and God bless you also!
Can’t wait to try your fabulous recipe and I’ll be back for a lot more recipes. Wonderful work Natasha.
I hope you love everything you try and find many new favorites 😉
I have to say, this cake is…perfection! I’ve loved chernosliv since I was a little girl, but whenever I tried to make one the recipes always failed me. I followed your recipe exactly and it turned out wonderful! I made it for a family Christmas gathering, and it was the first cake to be completely gone:) Thanks for this wonderful recipe…it’s definitely new favorite!
I sure do love this cake too. It’s one that took me a LONG time to perfect :). I’m so happy you enjoyed it. Thanks for sharing that with me!
