Knead flour, fat, sugar and vanillin sugar to a crumble dough. Grease a springform pan (26 cm Ø) and press 2/3 of the dough firmly onto it to form a base. Drain the peaches and spread on the base.
Stir the fat until foamy. Add sugar, vanillin sugar, lemon peel and lemon juice and mix. Add eggs. Stir in curd cheese and pudding powder. Spread the quark mixture on the peaches and crumble the remaining crumbled dough over them.
Bake in the preheated oven (electric: 200 °C/ gas: level 3) for 50 minutes. Remove from the oven, allow to cool slightly and remove from the mould. When cool, dust with icing sugar. Makes 16 pieces.
