For the yeast dough mix flour, sugar, salt, yeast and vanillin sugar in a bowl. Melt the fat, remove from the heat and add the milk. Add the egg and milk-fat mixture to the flour mixture and knead into a smooth dough with the dough hooks of the hand mixer. Cover the dough and let it rise in a warm place for about 30 minutes. In the meantime pour the apricots onto a sieve and drain well. For the quark mixture, whisk eggs, sugar, vanillin sugar and salt with the whisk of the hand mixer until creamy white.
Stir in the quark and lemon peel. Sift the pudding powder on top and stir in. For the crumbles, mix flour, sugar, almonds and salt. Add the fat in flakes and knead with the dough hooks of the hand mixer. Knead the yeast dough with floured hands and roll out into a circle (32 cm Ø) on a floured work surface. Place on a baking tray lined with baking paper and place a cake ring (32 cm Ø) around it. Carefully press the dough to the edge, cover and leave to rise in a warm place for about 15 minutes. Then cover the dough with the well-drained apricots, spread the quark mixture evenly and crumble the crumbles over it. Bake in the pre-heated oven (electric: 200 °C/ gas: level 3) on the middle shelf for about 45 minutes. Remove the cake from the oven, place the baking tray on a grid and use a knife to remove the cake from the edge of the cake ring (do not remove the cake ring yet). Let it cool down on the baking tray.
