For the apple-wine cake, knead all the ingredients for the dough well. If the dough is a little too sticky, chill for a short time. Pour the shortcrust pastry into a greased springform pan (26 cm diameter), raising a rim.
For the filling, slice or coarsely grate apples and place on top of the dough. Mix sugar, custard powder and vanilla sugar with 1/4 l wine. Bring remaining wine to a boil, stir in cold mixed pudding mixture and boil for about 1 minute.
Pour mixture on apples and bake at 180 degrees for about 1 1/2 hours. Then refrigerate for at least 1/2 day.
Whip cream with cream stiffener and sugar until stiff, spread on cake and sprinkle thickly with cocoa powder.
Preparation Tip:
The apple-wine cake also tastes good sprinkled without cocoa powder. Alternatively, you can also use cinnamon.
