Directions

1
Preheat oven to 350 °F (180 °C). Grease and flour a 9-inch (24 cm) round cake pan.
2
Beat egg whites to stiff peaks using an electric mixer. Gradually add sugar and beat for 2 more minutes.
3
Add egg yolks, sifted flour, milk, margarine and vanilla extract. Beat until a smooth, lump-free batter forms.
4
Add baking powder and beat at the lowest speed for exactly 30 seconds to keep the batter light.
5
Pour into the prepared pan and bake for 40 minutes, or until a toothpick inserted in the center comes out clean. Cool completely on a wire rack.
6
Make the frosting: beat the drained heavy cream with the softened butter until light and airy.
7
Add condensed milk, then sprinkle in the powdered milk gradually. Beat for another 2–3 minutes until thick and creamy.
8
Slice the cooled cake in half horizontally. Spread frosting on the bottom layer and add chocolate pieces or candies.
9
Place the top layer back, coat the entire cake with remaining frosting and drizzle with melted chocolate to finish.

💡 Chef's Tip

Chill the butter and heavy cream for 30 minutes before whipping for a firmer, fluffier frosting. Fresh strawberries between the layers make a beautiful and refreshing variation.
