Roll out the puff pastry or cake dough into rectangles, cut the apples into wedges. Arrange the apple wedges like a brick in the middle of the dough surface and sprinkle with sugar. Finally, brush the edge with egg.
Bake at 180 ° C for approx. 15 - 20 minutes.
When I serve it as a main course, I also serve applesauce with it.
Variant: use other fruits, such as apricots, plums, etc.
