How to Make Bird’s Milk Cake

Creating Bird’s Milk Cake takes a little love and patience—but every step brings you closer to a dreamy, melt-in-your-mouth masterpiece.

STEP-BY-STEP INSTRUCTIONS:

1. Bake the Sponge Cake

Start by preheating your oven to 350°F. In a mixing bowl, beat the eggs and sugar on high speed until pale and fluffy. This should take about 7–10 minutes. Gently fold in the flour and vanilla extract, being careful not to deflate the airy mixture. Pour into a greased 9-inch springform pan and bake for about 20 minutes, or until golden and springy to the touch. Let it cool completely in the pan.

2. Prepare the Soufflé Layer

Sprinkle gelatin over 1/2 cup cold water and let it bloom for 5–10 minutes. Meanwhile, heat the sugar and milk in a saucepan over medium heat, stirring until the sugar dissolves. Remove from heat and stir in the gelatin until fully melted.

In a separate bowl, beat the butter until fluffy. Add sour cream, vanilla, and lemon juice. Gradually pour in the warm gelatin mixture while continuing to beat until smooth and creamy. Pour this mixture over the cooled sponge layer in the springform pan. Chill for at least 4 hours, or until set.

3. Make the Chocolate Glaze

Melt the butter with milk in a saucepan. Stir in the cocoa powder and sugar until smooth and glossy. Let it cool slightly before gently pouring over the chilled cake. Tilt the pan to ensure an even coating. Return the cake to the fridge to set the glaze—about 30 minutes.

4. Slice and Serve

Once fully chilled and firm, run a knife around the edges of the pan and release the springform. Slice with a warm knife for clean edges.

HELPFUL TIPS:

• Beat Eggs Thoroughly: The sponge relies on the air you incorporate, so don’t rush this step.
• Don’t Overheat the Gelatin: Just warm enough to melt it—avoid boiling.
• Chill Between Layers: Be sure the sponge is completely cooled before adding the soufflé.
• Warm Your Knife: Dip in hot water for smooth, bakery-style slices.
