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.

Hey Natasha, I have a question about the honey prune cake. Do you have to do anything with prunes( like zapariti v kipitky or something) or just use them dry as it is?
No special prep required :). They soften with the cake 🙂
Thanks!:) Merry Christmas to you’re family!!!!! God bless!!!! P.S.Love, love you’re site!!!!!!
Loved this cake! 🙂 But since I didn’t have prunes and the cake is already so sweet I decided to use some fresh strawberries in between the layers! It’s like sweet & sour 😉 thanks for the recipe.
I love the idea of adding strawberries! Yum!!
what kind honey r you using home or store? (brand)
thankyou!!
It’s a raw Idaho honey that I found at Costco. You can use either kind 🙂
Excited to try this one for Thanksgiving!!
It really is a great choice for thanksgiving! I hope you LOVE it! I’ll either make this one or the POM Cake. I’m thinking to save the POM cake for Christmas 🙂
Ablosutely love this cake! It is our favorite:) Thank you for sharing!!
Thank you for a great review Mal, I’m glad you love it :).
YUMM!! I have made this twice already and everyone has loved it! It’s beautiful, looks complicated and absolutely delicious. Thank you, thank you for making me look like a pro! 🙂
Anytime ;-). I’m so happy you liked it!
Hello Natasha,
I’m from the Philippines and I am very inspired by your blog, keep it up! I have tried some of the recipes and they are great. I can’t wait to try the cupcakes and cakes though, maybe next year as I don’t have my oven yet but surely I will.
I hope you love every recipe you try! Thanks so much for your sweet comment 🙂
Hi there,
im just wondering can you tell me how many ingredients shall i need if i want to serve 5 people only instead of 12. and is it possible that i make a cake with layers of the prune honey cake and 8 layers honey cake? what im thinking is the cake can have the goodness of both deserts, is this even doable? Ireally want to combine them together
Thank you
Which honey cake are you referring to? I supposed you could cut the entire cake in half but I haven’t tried that so I couldn’t tell you exactly how different the bake time would be and it wouldn’t be a very tall cake unless you used narrower cake pans.
What percentage of whipping cream do u use for your cakes?
I use a heavy whipping cream. It should be at least 36% milk fat.
Thanks Natasha, it was a truly lovely recipe. I recently tried and came out just perfect, love to try this again.
I’m so happy you enjoyed it! 🙂
Where do u buy your prunes? Are they canned or fresh?
They are just regular dried prunes. These were actually organic prunes from Fred Meyer 🙂
Hi Natasha,
I finally got around to making this cake. When I took the cake out of the oven it fell and was not as fluffy looking as yours. I thinking it was slightly under baked…
But it has the classic chernisliv flavor and I love it. Not too sweet. Just perfect so I will try I again.
I’m so glad you enjoyed the cake! Aren’t the flavors amazing together? It sounds like it just needed 3 minutes more or so in the oven. It might be a difference in ovens. I didn’t see it really fall at all after I took it out of the oven. Anything else that could have been different in the process?
Made this cake for a fam get together. lovely cake!!!! I used only 1 cup of powdered sugar in the frosting since the batter had honey and sugar it it. I also zamachila the layers with a mixture of rum, water and sugar. the cake had 24 hrs to absorb all the deliciousness before it was devoured. It hit the spot Natasha, Thanks! Im trying your teramisu cake next :)))))))))
Ohh I love your variations already! Thanks for sharing how you changed it up. I love trying new versions! I’m so glad you enjoyed the cake. 🙂
I love this cake. I’ve been looking everywhere for this recipe. this is exactly what i wanted!! I made it. everything turned out perfectly. I made the frosting with plain greek yogurt instead of sour cream to save my family the extra calories and it tasted just as good as with sour cream!! my hubby couldnt even tell the difference… Im loving the greek yogurt for the extra protien and its nonfat. 😀
I love the idea of using plain G reek yogurt! You’re brilliant Lana! 🙂
making this asap! need to buy prunes today lol thanks for sharing!!!!
I am so bummed out right now! My cake didn’t rise. Basically one of my cakes is half the height as one of your cakes. I just hate when this happens. What do you think I did wrong? I know you said it didn’t work the first time….. did you have trouble with rising? I just want to make sure you meant what you wrote when you said it requires 2tsp of baking soda. I am now thinking maybe you meant to write 2 tbsp, but then that sounds like a lot:((((
I had trouble with the first two cakes that I made because I was using a completely different method. I haven’t had that issue with this method, they both rose really nicely. Did you do anything differently? It’s so hard to say what it could be without being there, but I’d love to help you troubleshoot it. Did you separate them into the pans equally? It’s defintiely 2 tsp and not 2 Tbsp 🙂
I re-read the recipe just to make sure I didn’t miss anything. Although my cake did not rise like yours, I still managed to cut each korzh into two, so the cake was high, but not fluffy. I also baked each cake layer for 28 min, which was too long for my cake since it didn’t have the capacity to rise anyway, but, I didn’t know that at the time I was baking it, so I over baked them. I decided to finish the cake anyway and It turned out good. My cake was not moist like yours, but it wasn’t dry either. I do think next time I will soak the prunes to soften them a bit . I knew I would have to adjust the recipe for the cream since I did not need as much (again.. due to my korzhi). I used one tub of sour cream, 1cup of heavy cream, 4 oz cream cheese, and sweetened the cream with condensed milk and I did not have any cream left over, so nothing went to waste. I will definitely try again. Maybe my flour played a role. I used all purpose Organic flour. I wonder if the amount of gluten in the flour can affect the cake and whether using pastry flour is better. Anyhow, I hate testing recipes, so that’s why we have you Natasha. Thank you for this recipe. I can understand why you didn’t give up on the cake! By the way, I did divide the cake evenly. It came out to be about 2 and 1/4 cups of batter for each layer. Now I wish I knew how much I was suppose to have. If you will remember to measure next time, this would really help. Thank you so much for all you do.
I think I was using an organic all-purpose flour also. I’m not sure what it could have been. Was the baking soda fairly fresh? Did you wait until the next day to eat it? It’s definitely more moist the next day. Sorry, I didn’t even think to measure the batter.
please help! my frosting didn’t come thick enough… what can i add to it (non-dairy stuff, please)?
What did you use if it’s non-dairy? Did you use something instead of sour cream? It isn’t supposed to be any thicker than sour cream.
i used Tofutti non-dairy sour cream…
I put some of the liquidy frosting in between layers and on top. the rest of frosting went to the freezer. if it becomes anywhere near the supposed consistency, I can still put it on the cakes sides. the cake is on the porch (i’m in NYC, so the temperature is right at least for that 😉 ) and will serve it on sunday, so have time to see.
oh, and your easy bread kvas is a staple at my parties now 🙂 (although I think I overdid a bit with sugar this time)
almost forgot – also making 2 salads, a dressing, and one main dish (plov with chicken) from your site 🙂
That’s so great! Thanks for sharing that with me dear 🙂
It will be less sweet over time as you know 🙂 I’m so glad you love the kvas 🙂
Yeah it’s not supposed to be a super thick frosting, but I haven’t worked with the Tofutti before so I can’t really advise on what to mix into it. I hope you love the cake! 🙂
Natasha thank you for perfecting and sharing this recipe! I’m amazed how this cake rose nicely! It’s delicious! Like someone stated, my organic honey didn’t turn yellow. The honey is really dark to begin with, but it turned out perfecto! Love the chemical reaction too 🙂 I made one yesterday(took it to a prayer meeting) and now thinking and weighting my energy levels if I could make another one right this evening…
Thank you for such a good report Irina :), did you have enough energy to make the second cake?
sadly I didn’t get to make it that evening, but I seriously making it one of these days!
Hey Natasha,
I just made this cake and cant wait to try it tomorrow:)
It turned out so high:) so now Im trying to come up with ideas how to pack it and deliver it to the party which is an hour away:) oh boy!!!
Enjoy it! If you get a chance, I’d love to see how you decorated it! Did you post a pic online?
My decoration was nothing special. Just covered the whole cake and sides with roasted walnuts. But prunes and walnuts are perfect combo!!!
Everyone loved the cake! Thanks again!
Wow! I love the way you decorated it!!! So pretty! I have a quick question. This cake looks pretty tall, if I was to use an 8 in pan, should I cut the recipe in half? I wouldnt want a super tall cake…
This was made with a 9″ cake pan and making it in an 8″ pan; you might make 3/4 of the recipe or you’ll end up with a pretty small cake.
