How to Make Bird’s Milk Cake
-
Measure Ingredients: Start by weighing all your ingredients accurately with a kitchen scale. Line two 8-inch round baking pans with foil or parchment paper, and wrap wet baking strips around the pans to ensure even baking.
-
Preheat Oven: Set your oven to 350°F and place the rack in the middle to create a perfect baking atmosphere.
-
Whip Egg Whites: In a clean, large bowl, add the egg whites and whip on high speed until they become foamy, which should take about 30 seconds.
-
Add Sugar Gradually: Slowly incorporate the granulated sugar while continuing to whip, maintaining this high speed for about 7 to 10 minutes until you achieve glossy peaks.
-
Sift Dry Ingredients: For the Cake Batter: Sift 120 grams of all-purpose flour and 40 grams of cocoa powder over your fluffy egg whites. With a gentle folding motion, combine the mixtures until almost no dry streaks remain.
-
Divide and Bake: Carefully divide the batter evenly between the two prepared baking pans. Bake in your preheated oven for about 20 minutes, or until a toothpick inserted in the center comes out clean. Avoid opening the oven door before 17-18 minutes to ensure the cakes rise properly.
-
Cool the Cakes: Allow the cakes to cool in their pans for about 5 minutes. Then, gently invert them onto a cooling rack and remove the parchment or foil. Let them cool completely.
-
Make Custard Buttercream: For the Egg Yolk Custard Buttercream: In a saucepan, combine 3/4 cups sugar and 10 egg yolks. Whisk them together until well combined.
-
Combine with Milk: Pour in 3/4 cups of whole milk into the saucepan and whisk until smooth.
-
Cook the Mixture: Cook the mixture over medium heat, stirring continuously until it thickens. Make sure it does not boil.
-
Cool Custard: Let the custard cool to room temperature before using it in your buttercream.
-
Whip Butter: In a mixer, whip the unsalted butter for about 5-7 minutes until it is fluffy and pale in color.
-
Add Custard and Flavor: Gradually fold in the cooled custard and 1 tablespoon of vanilla extract in two additions, whipping thoroughly after each one.
-
Reserve Buttercream: Set aside about 1.5 cups of the buttercream for frosting the outer layer of the cake later.
-
Layer the Cakes: Carefully slice each cake layer horizontally into two equal parts to create four layers in total.
-
Frost Layers: Place the first layer on a serving platter and spread 1/3 of the Egg Yolk Custard Buttercream on top. Repeat this step with the remaining layers, finishing with the cut side of the second layer facing up.
-
Create a Crumb Coat: Lightly cover the entire cake with a thin layer of the reserved buttercream to trap in the crumbs.
-
Prepare Chocolate Ganache: For the Ganache: Combine 1/4 cup of hot cream with 1/4 cup of semi-sweet chopped chocolate and let it sit for 1-2 minutes. Stir until you have a smooth mixture.
-
Drizzle Ganache: Pour the beautiful ganache over the cake, letting it cascade down the sides, creating an elegant finish.
-
Decorate: Lastly, using a piping bag, decorate the cake with the reserved buttercream, creating delightful stars. If desired, sprinkle some cocoa powder or add chocolate-covered coffee beans for an extra touch!
Optional: A sprinkle of sea salt enhances the chocolate flavor beautifully.

Bird’s Milk Cake Recipe FAQs
What kind of egg whites should I use for the Bird’s Milk Cake Recipe?
Absolutely use fresh egg whites for the best aeration! They should be at room temperature as this helps achieve maximum volume and lightness. Avoid any that are more than a few days old, as older egg whites may not whip as nicely.
How should I store leftover Bird’s Milk Cake?
For room temperature storage, keep leftover slices in an airtight container for up to 2 days. If storing in the fridge, place it in an airtight container and enjoy within 5 days. For the best flavor, allow it to come to room temperature before serving.

What should I do if my egg whites aren’t whipping properly?
Very frustrating, isn’t it? If your egg whites aren’t whipping well, ensure your bowl and whisk are squeaky clean and free of any grease or yolk, as any fat can prevent them from aerating. If that still doesn’t work, check the freshness of your eggs; older eggs tend to produce weaker foam.
Can I make this recipe dairy-free or gluten-free?
Absolutely! For a dairy-free version, swap out the unsalted butter with a dairy-free butter alternative. Use almond milk or coconut milk in place of whole milk for the custard buttercream. To make it gluten-free, substitute the all-purpose flour with a gluten-free flour blend, just be sure to check that it has a binding agent like xanthan gum included, or add it yourself!
