Mix 100 g quark, milk, 1 egg, oil, 50 g sugar, vanillin sugar and salt with the whisk of the hand mixer. Mix flour and baking powder and fold into the quark mixture.

Bake in the preheated oven (electric: 200 °C/ gas: level 3) for 25-30 minutes. Let cool on a cake rack. Heat up the jam and spread on the apples and the edge of the cake.
