Grease the drip pan. Peel the apples and cut lengthways into wedges. Immediately drizzle with lemon juice.
Mix the flour, 375 g sugar and salt. Add 3 egg yolks and butter in flakes. First work with the dough hook and then briefly with your hands into sprinkles. Spread about 2/3 of the crumble on the drip pan and press down as a base. Place the apple wedges close together.
Beat the cream, 5 eggs, 125 g sugar and vanilla sugar for about 1 minute until frothy. Pour over the apples. Spread the remaining crumble on top.
Bake in a hot oven at 200 ° C top / bottom heat (convection 175 ° C) for about 50 minutes.
Allow to cool after baking and dust with powdered sugar.
