Bird’s Milk Cake (Ptichye Moloko) is a very common and beloved Russian dessert made with light, airy layers of cream, cacao custard, and chocolate ganache. Most people that grew up in a Slavic household dream about its luscious, creamy texture and pray one of their family members will bring it to the next big get-together!

Wondering about Bird’s Milk Cake history and origin? You’re not alone. The name is a bit strange and eyebrow- raising (spoiler alert: no bird’s milk is required!). It was born out of a Slavic folktale surrounding the mythological milk birds of paradise feed to their baby chicks.

According to the legend, eligible maidens would challenge their suitors to find the elusive milk and bring it back to them. This of course was impossible, but you can see just how serious these maidens were about securing their future. Today, Bird’s Milk Cake is enjoyed throughout Europe and can be found in many European specialty stores stateside. No maiden challenge required!

How to Make Bird’s Milk Cake

Making Bird’s Milk Cake requires a bit of patience, but the end result is more than worth it. Below, find a quick hitter overview of the recipe before you dive in.

  • Make the Batter Base: Dissolve the gelatin into the milk in a saucepan over medium heat. Remove from heat and set aside. With a stand or hand mixer, whip together the Cool Whip, sour cream, and sugar. In small portions, beat the milk/gelatin mixture in until smooth.
  • Allow the White Layer to Set: Grease the cake pan. Place half the batter into it and refrigerate until the white layer hardens (around 30 minutes).
  • Make the Cacao Layer: Using the stand mixer or hand mixer, beat the cacao powder into the remaining half of the cake batter. Set aside to cool to room temperature.
  • Add the Cacao Layer: Carefully spoon the cacao layer on top of the white layer. Allow both layers to set in the fridge (about 30 minutes).
  • Make the Chocolate Ganache: In 30-second intervals, melt the chocolate chips and heavy whipping cream. Between each round, give the mixture a good stir.
  • Plate & Frost the Cake: Loosen the edges of the cake, carefully flip it upside down onto a cake stand or serving plate, and gently remove the pan. Spread the ganache on top of the cake, letting it drizzle off the sides. Top with fruit and pop back into the fridge for 2 hours for a final set. Serve and enjoy!

Tips for Making the Best Bird’s Milk Cake

  • Allow each layer to set for 30 minutes. Patience is a virtue with Bird’s Milk Cake! Allowing each layer enough time to set is crucial to creating the perfect slice.
  • Use a spatula to smoothen the cacao custard layer. To ensure a smooth bottom (you’ll end up flipping the cake when you plate it), use a cake spatula to smoothen the cacao custard layer flush to the top of the cake pan.
  • Smoothen the sides of the cake after plating it. Once you flip the cake upside down and remove it from the pan, smoothen out any rough edges using the flat side of a butter knife or a cake spatula.
  • Make Bird’s Milk Cake a couple of days ahead. To allow the cake to really develop and set perfectly, you can make it up to two days in advance before serving it.

Springform Pan Hack: Use a springform pan to take the stress out of removing the delicate cake layers from the cake pan.
