Put flour and baking powder into a mixing bowl and mix. Add the fat, 125 g sugar, vanillin sugar and the egg and fold in with the dough hooks of the hand mixer. Finally, knead quickly with cool hands to a smooth dough.
Leave covered for about 30 minutes in a cool place. Peel apples, remove seeds and cut into cubes. Sprinkle with lemon juice. Mix 1/4 litre wine, pudding powder and cinnamon. Boil up the rest of the wine and sugar and add the pudding powder, stirring constantly.
Bring to the boil while stirring and then allow to cool slightly. Roll out the dough on a lightly floured work surface to a thickness of about 0.5 cm. Line a greased springform pan (26 cm Ø) with it and prick several times with a fork.
Drain the apples and spread them on the dough. Pour the slightly cooled pudding mixture over it. Bake the cake in a preheated oven (electric: 175 °C/ gas: level 2) for approx. 11/2 hours. Let the cake cool down overnight.
Heat the jam in a pot while stirring and spread the cake with it. Cut the cake into pieces and serve decorated with cherry apples, apple slices, cream, cocoa and mint leaves as desired.
Results in about 12 pieces.
