Beat granulated sugar with butter until frothy, gradually stir in the eggs. Mix the roughly chopped nuts and the roughly chopped chocolate with baking powder, vanilla sugar and flour. Stir together with the grated apples and the egg mixture and bake at 160 ° for about 1 hour in a previously buttered pan sprinkled with breadcrumbs.
Tastes very juicy and has a long shelf life. You can also glaze the cake with chocolate.
