Grate the chocolate. Place the fat, salt, vanillin sugar and sugar in a mixing bowl and mix to a creamy mixture with the whisks of the hand mixer. Add the eggs bit by bit. Mix flour, cinnamon, baking powder, hazelnuts and chocolate rasp and stir in alternately with the milk. Line a muffin tin (12 troughs) with paper cups and distribute the dough evenly.

Melt the chocolate icing in a water bath. Decorate muffins with chocolate icing, almonds, hazelnuts and cherries
