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 want to make this as a large rectangular cake for a large group. What size pan would I need and should I double or triple the recipe?
Hi Nadia! I have not tried different size pans to know how to adjust that recipe accordingly. I’m sorry.
If I only have one baking pan, do I just let half the cake mix stand in room temperature until the first one finishes?
Hi Lily! This batter should be baked right away. If it sits, it will deflate and the texture can be rubbery and flat.
Hi, can I freeze this cake whole ? Is it freezer friendly ? Thank you
Hi Alina, generally cakes freeze well, I imagine this one will also. I hope you love it.
Instead prune, I put blueberries and raspberries .and honey 6-7 .Frozen cake tastes extra delicious
Sounds delish!
Loved this cake! Do you think the batter could be used for cupcakes?
Hi Karina, I haven’t tried this as cupcakes, but here is what one of my readers wrote: “1. Cupcakes: I wanted to test this recipe, so I made half a batch of batter, added blue berries (the prunes just didn’t work for me), and spooned it into a 12 serving muffin tin sprayed with non-stick cooking spray (fill each cup almost full with batter.They will be taller and a better color). Next time, I’ll put the batter in a ziplock bag, cut the corner, and pipe it to avoid the mess. Be sure to flour the berries to keep them from sinking. I forgot. I cooked as directed above, but only 10-turn-10 minutes. At about 12 minutes, they were looking very brown so I covered them with tin foil. Be sure to spray the foil to keep it from sticking.
The results were amazing. They have a flavor reminiscent of a sugar cone. It dissolved in my mouth. I can’t imagine how decadent they would be with a frosting. The cream+sour cream recipe above might be very, very good.” I hope this helps!
Hi Natasha why is the sponge not rising evenly? What the problem can be?
Hi Tina, several different factors could explain why it didn’t rise or rise evenly. I recommend ensuring there were no substitutions made to the recipe. Also, I recommend double-checking the steps with the honey, and baking soda – those steps are critical to activate the baking soda and have the cake rise properly – also, be sure you are beating the eggs and sugar at high speed with a high-powered mixer.
I’ve been making this cake for years. It’s always been a smash hit, always have my uncle’s ask for me to make them their own. Lol
That’s just awesome! Thank you for sharing your wonderful review, Suz!
Absolutely the best, everyone enjoys this cakes and it usually gone in minutes!
That’s just awesome! Thank you for sharing your wonderful review, Alina!
Hello Natasha, Could you tell why my frosting is runny? Do I need add more powdered sugar?
Hi Zhenya, make sure to use HEAVY whipping cream and beat until stiff and spreadable. Also, make sure to use a thick full-fat sour cream like the Daisy brand one that I have in the photos and that will help. If the heavy cream was not beaten enough it will be difficult to thicken it up after that.
This is one of my favorite cakes to bake and eat, it’s so decadent, and I’ve made it far too many times now for years.
The only changes I do is tort the two cake layers into four pieces, so in all, I have eight layers. I find that thinner layers soak up the sour cream frosting better and the cake is so much more moist.
Next, instead of putting 32oz of sour cream into the frosting, I put 16oz, because with 32oz it’s very thin and I would always have lots of extra frosting. 16oz is perfect to frost the whole cake.
Thank you for the recipe Natasha <3
Nice, thanks for sharing some of the changes that you’ve tried for this recipe. I’m glad you loved it!
This cake is amazing! Ive made it countless times. However every time i make the frosting, it comes out super thin. It’s impossible to frost with. I always need to add extra heavy whipping cream and powdered sugar to thicken it. I follow your recipe exactly but always have trouble with the frosting. Any ideas why?
Hi Natasha, are you sure you’re using heavy whipping cream and not just whipping cream?
Would this be good with added nuts? Would you toast them if so? Or better without?
Hi Mary, I haven’t tested that to advise. If you happen to experience I would love to know how you like that.
Hi Natasha! This cake looks amazing and I can’t wait to bake it. I was wondering if I could make the cakes one evening and frost them the next day? I have 4 little children and I can easily get overwhelmed with baking..
Hi Lydia, That should work! I hope you love this recipe!
Hi, Natasha!
I noticed you use a 9-inch cake pan for a lot of your desserts. How deep is your cake pan? I’m looking at purchasing a couple of pans and I am having trouble deciding on the depth. What size, in depth, do you tend to use most?
Hi Victoria, I believe it is 2.5 inches but our favorite tools can be found in our blog shop HERE.
