Extremely delicious, day and night cake in 10 minutes in the oven

First, beat the butter, sugar, vanilla sugar, 2 eggs and 5 egg yolks until fluffy. Add flour and baking powder.
Beat 5 egg whites until stiff and fold in. Spread 2/3 of the dough onto a greased baking tray.
Mix 1/3 of the dough with 2 tbsp cocoa powder and use a spoon to place small heaps on the already spread dough.
Then bake in a preheated oven at approx. 180°C for approx. 20 to 30 minutes.
Spread ¼ l of hot milk on the still hot cake with a spoon and allow to cool.
Our tip: For chocolate fans, you can then spread a chocolate glaze on top.
