Cake “Black Prince”

Cake "Black Prince"

I am not sure why this cake is called “Black Prince”, but I do know that this same recipe has at least 5 other names that I have heard it go by. I’ve found that almost everybody who lived in Russia has some variation of this cake recipe and that is not to say that Americans don’t.

You can find similar recipes, with the only difference being that sour cream is sometimes replaced by yogurt, sometimes buttermilk, others decide to substitute it with vegetable oil. And no wonder it is such a popular cake worldwide it seems – it definitely is one of the best tasting cakes. Dense, moist with a certain creaminess from the condensed milk frosting, or as I call it – Russian buttercream.

The versatility of the cake layers is also another reason this cake is popular in the Russian community. Each layer can be different, depending on what you want to add to it. You can make your cake all chocolate, or all poppy seed, or all raisins, or all white vanilla cake, or alternate the flavors of the cake layers to your liking.

Cake "Black Prince"

Those that have attended my baking class will recognize this cake as this is the same cake I demonstrated making and decorating. I have edited the recipe a little after the class, to clarify some things that were mentioned in class, but were not in the recipe.

When giving somebody a recipe, I always say that if you’ve never baked a thing in your life you can still make this cake, it is that easy and straightforward.
The original recipe does not call for additional frosting for decorating, but I always find that given frosting is only enough to layer the cake and make it delicious. I always add 2 cups of whip cream (whipped to stiff peaks) to decorate the outside of the cake.

The cake shown above is a 6-inch cake, made with half the ingredients listed below and I have decided to use only chocolate & poppy seed for my cake.

Prep Time: 20 minutes
Cook Time: 20 minutes
Total Time: 40 minutes


Ingredients for the Royal Cake

  • 2 cups granulated sugar
  • 2 cups flour
  • 4 eggs
  • 3/4 cup poppy seeds
  • 3/4 cup raisins
  • 3/4 cup chopped nuts walnuts or pecans work best
  • 2 tblsp. cocoa powder
  • 4 tsp. baking soda
  • 4 tblsp. Vinegar


  • 500 g unsalted butter room temperature
  • 2 cans sweetened condensed milk as is, or cooked**

For decorating:

  • 2 cups heavy whipping cream at least 36% fat content
  • 2-3 tablespoons powdered sugar
  • 1 tablespoon vanilla extract


  1. Turn the oven to 350F.Apply some butter to the inside of the baking pan and dust with flour. Shake out the excess. Alternatively you can spray it with nonstick cooking spray. Set aside.
  2. Mix 1 egg with ½ cup of sugar, add ½ cup sour cream, 1 teaspoon baking soda mixed with 1 tablespoon vinegar, ½ cup flour and ¾ cups poppy seeds. Mix everything thoroughly until smooth and creamy, then pour out into the baking pan. Bake until a toothpick inserted in the middle comes out clean, about 15-20 minutes.
  3. Second layer - Follow the instructions above (step 3), but replace poppy seeds with 3/4 cup raisins.
  4. Third layer - Follow the instructions in step 3, but replace poppy seeds with ¾ cups nuts.
  5. Fourth layer - Follow the instructions in step 3, but replace poppy seeds with 2 tablespoons cocoa powder.
  6. Invert the cakes onto a wire rack and let cool
  7. Split the cake layers into two thinner layers *optional.

To make the frosting:

  1. In a bowl of mixer, with the whip attachment, whip the butter until whiter in color and fluffy, about 2-3 minutes.
  2. With the mixer still running, slowly pour the condensed milk, against the inside wall of the mixer bowl, until fully incorporated and fluffy. As soon as the condensed milk is added, with some streaks of the condensed milk still showing, turn the mixer off and fold the frosting until fully combined.
  3. **To cook sweetened condensed milk, take the paper label off, place it in a deep pot, cover with water so that the water covers the cans at least 2 inches. Cover with lid and bring the water to boil. Cook on medium heat for 1.5 hours. Do not let the water evaporate and add hot water as necessary. Take off the heat and cover with cold water until the cans are cool.
  4. To assemble:
  5. Layer the cake with frosting.

To Decorate:

  1. Whip the cream with a mixer (whip attachment), gradually increasing the speed as the cream thickens. When the cream is somewhat fluffy, add the powdered sugar and vanilla extract and continue beating until the whisk creates visible ripples and is very thick.
  2. Cover the cake in this frosting and decorate to your liking.

Recipe Notes

Refrigerate the cake overnight. Serve at room temperature or cold out of the fridge, depending on how you like it.

    Hi Marina! So i was whipping the heavy cream and it started to look fluffy and then added sugar and vanilla extract. In a minute the cream become somewhat like cottage cheese. What did i do wrong?

    • That’s what overwhipped whip cream looks like. You need to whip for less time. If you whip for too long, you will take your cream to a butter stage, that’s when solids and liquids separate and you get butter.
      Next time start to to add the sugar as soon the whip cream begins to thicken, and stop whipping when it just holds peaks.
      If you do overwhip, add a little bit of cream (liquid) and mix again, and it should come together again. If you beat too long though, it could be unrepairable.

    Hi, I absolutely LOVE your website! God bless you and keep up the awesome work! 🙂 Maybe I missed it but I don’t see a baking time for the layers in this recipe–?

    • Hi Yana, thank you for your wonderful comment 🙂 I appreciate it 🙂
      There’s no specific baking time because depending on your oven, type of pan and the amount of batter, the times will vary. You can bake it for about 13+ minutes (really depends) and once it starts to smell like cake in your kitchen, you can open the oven and check with a toothpick (in the middle), if it comes out clean, then you can remove the cake from the oven. Do not overbake or the cake will not be moist. 🙂
      Once again, thanks for your comment 🙂

    So for the cake that you photographed here, did you bake only 1 layer poppy seed and then 1 later chocolate? And then just cut each in half to get 2 layers of each? And how long do the layers bake approximately?

    · Reply
    • If you have two baking pans then you can make the batter at the same time, then split it in two, add poppy seeds to one half and cocoa to another. Stir. Pour poppy seed batter into one pan and cocoa batter into another one. Bake at the same time.
      If not, just split the proportions in two and bake one at a time.
      You can follow instructions for baking times from the recipe, but as soon as a toothpick inserted in the middle comes out clean, the cake layers are done.

    To make a cake shown in the pictures (with 2 chocolate and 2 poppy seed layers) should I cut the entire recipe in 1/2? You said 3/4 in the beginning and I’m a little confused….

    · Reply
    • If you want to make a 6 inch cake, then split the recipe in half.
      If you want an 8-9 inch cake then take only 3/4 of the ingredient amounts
      for a 10 inch cake, do not change the recipe amounts.
      Hope this helps, if it does not, let me know.

    for the cake in your picture, did you use cooked or uncooked evaporated milk in the frosting?

    · Reply
    • It’s sweetened condensed milk, not evaporated milk.
      For the cake in the picture I used uncooked, but you can you either. I personally like it with cooked, but some of my family likes it with uncooked.
