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.

I am so in love with this cake:) Made it like for three parties already. Thank you again!
That’s fantastic!! You’re so welcome. I hope to bring you many more new favorites this year 🙂
Hi Natasha,
I made this cake this weekend and it is very good. Thank you for the recipe. I have one question. What is the easiest way to get the chocolate shaving onto the side of the cake?
Good question. There is no “easy” way. I tilt the cake (very gently) and after dusting on the first round with my hands (I’m almost tossing it at the cake), I scrape the excess chocolate off the base being careful not to get it into the frosting and pat it with my hand onto the cake for a more even finish. Truth be told, if there is a secret easy method, I haven’t discovered it. I think a rotating cake stand would work well, but I don’t have one yet 🙂
Natasha thank you for a truly wonderful cake. Made it for my husbands b-day and everyone loved it. I enjoy making different kinds of cakes as a hobby, but I don’t always have more than 2 slices of it, but with this one it was different. I kept eating it and eating it. It was just delicious and addicting. The flavors went so great with one another. From the honey cake layers to the sour cream frosting to the prunes. Best of all it was so easy and uncomplicated to make. Thank you again and I can’t wait what cake you come up with next 🙂
Thank you Inna! I’m so glad you loved it. Your comment makes me so happy that I didn’t throw in the towel after my first two flops 😉
Wow! Prunes in the Honey cake. What a wonderful idea, Natasha.
This cake was gone quick, very nice mix of flavors :).
Hi Natasha! I’m making this cake for a Russian dinner party I’m attending this week. Just one question – do you refrigerate the cake during the day prior to when you eat it? Thanks!
Yes refrigerate overnight or keep it in a very cold garage covered with plastic wrap.
Thank you so much Natasha for amazing recipe! Today I made this cake the second time already. My kids and my husband love the honey and baking soda part. The cake rises so well and very soft, my grandma loves this cake.
I’m so happy you all love the cake, even Grandma 🙂 That’s very sweet. Thanks for sharing that with me!
I made this cake and it turned out really good! I love it but for some reason I made the frosting by the directions and that was way too much I ended up using only half of it. Are you sure you didn’t mean 16 oz of sour cream not 32?? Just asking cuz I ended up with way too much frosting. But the cake was really good thank you for the receipe
Yes, it is 32 oz 🙂 I used both the 16 oz tubs photographed. I had maybe 2 Tbsp left over (not much). Did you frost both the top and bottom of each layer? Adding more between the layers ensures a more moist cake the next day 🙂 I’m so glad you liked the recipe!
Natasha, thank you so much for this recipe! It is a winner and definitely a favorite! I have been looking for a good prune cake recipe for a long time, and when I saw this I went right to work. This cake is amazing. Got so may “omg’s” and “wow’s” from people!:)
May God bless your kind sharing heart!
That’s music to my ears 🙂 You must have done an amazing job getting all those omg’s and wows 😉
Lol. Maybe I am. Nurses are weird like that. I am not even gonna say anything else about prunes lol
Lol I know exactly what you mean. Hahaha
This cake is amazing!!! This is my new favorite. I made it for the New Year party and it turned out great. The prunes go really well with this cake. I enjoyed the soda/honey chemical reaction too. It was pretty cool. And I see why you have to be very careful, so it does not get overcooked, as it browns very fast. I was very impressed by the end results. Thank you very much!
Yay!! I’m so glad you loved it and also enjoyed the chemical reaction. I’m not the only nerd here. 😉 Not that you’re a nerd. Oh goodness, nevermind. lol. Thanks so much for your awesome feedback!
What a great cake!
I’ve been making a very similar version for years and it was my go-to recipe for birthday cakes that I would bake for my siblings:) before I got married and went on my merry way to Florida.
I love how fluffy and moist it is. It’s also so versatile, literally a blank canvas, and add so many different toppings and fillings. I’ve never tried adding prunes yet. Sounds like a delicious addition.
The recipe I use is exactly the same except a bit less honey, but I’ve never cooked the honey, just added it to the batter just the way it is. Sounds really intriguing.
Cooking it together with the baking soda has provided the best results for me. Otherwise, I ended up with a caved in center. These cake layers were perfect. And the reaction between the honey and baking soda is really cool!! 🙂
I made this cake and it was delicious. Everyone loved it. Thank you Natasha for sharing!
Awesome!! I’m so glad you all enjoyed it 🙂 Did you post a pic of it anywhere online? I’d love to see it!
Hi Natasha,
Thank you so much for the recipes you post!!!
I just baked the cake, but silly me got distracted and forgot to add the last 1/2 of flour oops:/ unfortunately I realized that already when they were in the oven.. I was so disappointed that they probably won’t turn out, but luckily they came out nicely well not exactly as tall as yours though. I’m happy I don’t have to redo it.. Can’t wait to try it tomorrow
Wow that’s great!!! You know it’s a great recipe when it works with half the flour. lol. I hope you love it anyways 😉
This cake is on my list to make tonight!!!! Natasha, you are so sweet to share all your creations with us!! God bless you and your family!
-Your loyal fan!!!!
Thank you for such a sweet comment Alla, I’m truly honored. Blessing to you and your family as well :).
OMG this cake is a hit at my house!! Family’s favorite so far. Kievsky cake was the favorite for a long time and now this one is by far our favorite!!! Not sure what I would do without your website… so so thankful!
Alla you are the sweetest. And I’m so so thankful for you! 🙂
Another question for my churches new years potluck. Would it work if i made this cake square? Or maybe a little bigger? because its really hard to cut it and put it on plates when its so tall and round. I think it would work better if at least it wasn’t so tall. Any suggestions? Thank You
I think it would work in two 9×13 baking pans. The baking time might be a little different (maybe a little less time in the oven).
Hello, I don’t know if you used raw unfiltered honey, but for anyone that does make sure the honey melts all the way before adding the soda. My honey was crystallized and the first time it wasn’t completely liquid so the cake didn’t rise that well. Also for some reason raw unfiltered honey doesn’t turn yellow even after ten minutes of stirring. It stay a light caramel color, but the cake still turns out good and rises well. Thank you for all your amazing recipes!!!
Thank you for sharing that Anna 🙂
Hi, Natasha! Thank you for your wonderful recipes. I’ve used quite a few of them, and everything turns out delicious! I just finished assembling this cake (your instructions are super clear), and it looks picture-perfect! I’m sure it tastes as good (will be eating it tomorrow). Want to wish you a very Happy New Year and many blessings from our Lord!!!
Thank you Venera for such a good report. Happy New Year to you as well 🙂
Hi Natasha! Just made the cake part and it came out super dry and hard. Don’t know what went wrong, it didn’t rise either. Gonna attempt it again in the morning.
It’s hard to say what went wrong without being there with you. But we will try to troubleshoot. Did you follow all the instructions without changing anything? Did you use all the same ingredients without substitutions? The layers should be soft and tall.
hello natasha… I was wondering what is the reason u cook your honey and baking soda?
Will it work if I just added honey and baking soda to the batter instead of cooking? I’m worried mine won’t turn out well for my party. and I just don’t have time to practice 🙂
and thank u thank u for your wonderful blog! Happy New year!!
I’ve tested with by adding baking soda with flour and it did not work well. Heating the honey and mixing in the baking soda gave me the best results, so this is the method I would recommend. Honey activates baking soda.
Ahhh sorry just saw your comment about it being eaten the next day :-D!!!
Yes! It’s better with time (which is also super convenient because you don’t have to make it the day of your party) 😉 Enjoy it!
