Mix flour, 1 sachet of vanilla sugar, 200 g sugar, cocoa, salt and baking powder. Add 2 eggs and 275 g fat, work into a smooth dough with the dough hooks of the hand mixer and leave to rest for about 30 minutes.
Melt the remaining fat and let it cool down a little. Drain the cherries. Mix quark, remaining sugar, remaining vanillin sugar, remaining eggs, pudding powder, sauce powder and remaining fat.
