Separate 2 eggs for the bottom. Put the egg whites in a mixing bowl and chill. Cream fat, 100 g sugar, salt and 1 packet vanilla sugar with the whisks of the hand mixer. Add egg yolk and 1 egg and stir in. Mix flour and baking powder and add alternately with the milk and stir in. Grease the bottom of a springform pan (26 cm Ø) and sprinkle with breadcrumbs. Fill in the dough and smooth it down.
Beat the egg whites with the whisks of the hand mixer until stiff, adding 100 g sugar. Spread the egg white loosely on the dough. Bake in the preheated oven (electric cooker: 175 °C/ gas: level 3/ convection oven: not suitable) for 30-35 minutes. Remove from the oven, immediately remove from the edge of the springform pan and allow to cool on a grid in the pan. In the meantime, wash apples thoroughly, quarter them, remove seeds and cut into slightly thicker slices. Bring apple juice to the boil in a pot. Add apple slices and stew covered over low heat for 2-4 minutes. (Should only become soft, must not fall apart). Carefully pour into a sieve, collecting the juice. Let the apple slices drip off very well. Pour juice into a measuring cup and fill up to 450 ml with water. Remove 4-5 tablespoons, mix with custard powder and 25 g sugar. Bring the remaining liquid to the boil in a saucepan, stir in the pudding powder and simmer over a low heat for about 1 minute. Remove from the heat and allow to cool slightly while stirring several times.

Spread the thickened juice evenly over the apples from the middle. Let it cool down at room temperature. Place cream, sour cream, 2 packets of vanilla sugar and sauce powder in a mixing bowl and whisk until stiff. Spread loosely on the apple mixture. Serve as desired, decorated with steamed apple slices and mint
