Instructions
Tip: tap a step to mark it as done.
Mix the batter
Separate the eggs. Thoroughly mix the sugar, flour, cocoa powder, baking powder, oil, water and egg yolks.
Bake the sponge cake
Beat the egg whites until stiff peaks form, then gently fold them into the batter. Pour the batter into a baking sheet lined with parchment paper and bake in an oven preheated to 180 °C (350 °F) for about 20–25 minutes. Let the baked sponge cake cool.
Make the frosting
Lightly beat the sour cream and spreadable butter together, then add powdered sugar and rum to taste. Whip the heavy cream with the vanilla sugar and gently fold it into the sour cream mixture.
Finish the cake
Spread the frosting over the cooled sponge cake and generously cover with grated dark chocolate. Chill the cake in the refrigerator, then cut into pieces.
Tip: Refrigerate the dark chocolate for at least half an hour before grating so the warmth of your hands does not melt it and the shavings stay dry and separate.
