Cream fat and sugar. Stir in eggs bit by bit. Add vanilla pulp. Mix flour and baking powder and gradually stir into the fat-sugar-egg mixture. Add hazelnuts and spices. Peel the apple and cut out the core. Coarsely grate the apple and sprinkle with lemon juice.
Add to the dough and mix. Grease a medium sized ring cake tin and sprinkle with breadcrumbs. Pour in the dough and bake in a preheated oven (electric: 175 °C/ gas: level 2) for about 1 hour. Let it cool down a little bit, remove from the rim with a sharp knife and turn out of the tin. Let it cool down well on a cake rack and dust with icing sugar and cocoa. Makes about 12 pieces
