Wash the apples and cut out the core with an apple corer. Place apples side by side on a baking tray. Bake in a preheated oven (electric cooker: 175 °C/circulating air: 150 °C/gas: see manufacturer) for 55-60 minutes.
Remove from the oven, place on a rack and allow to cool slightly.
Roast the almonds in a pan without fat until golden brown. Remove apple flesh from the skin with a tablespoon, place in a bowl and mix coarsely. Stir in the juice from the baking tray.
Put approx. 5 tbsp. of compote aside. Separate eggs. Stir 5 tbsp. milk, 50 g sugar, vanilla sugar, pudding powder and egg yolk until smooth. Boil up the rest of the milk,.
Stir in the mixed pudding powder. Simmer again for about 1 minute while stirring. Remove from the stove. Let the pudding cool down while stirring frequently.
Beat the cream and egg whites separately with the whisks of the mixer until stiff. With the egg whites, pour in 1 heaped tbsp. sugar. Fold the pudding, cream and beaten egg white into the cold apple compote in portions one after the other.
Decorate the baked apple cream with the rest of the compote, flaked almonds, icing sugar and apple slices as desired.
