Grease baking tin (for Gugelhupf confectionery; 24 troughs) and dust with flour. Grate marzipan finely. Whip the marzipan, eggs, vanillin sugar and 125 g icing sugar with the whisk of the hand mixer until thick and creamy. Add oil slowly and mix. Mix flour and baking powder, sieve over it and fold in until a smooth dough is formed. Colour the dough pink with food colouring
Pour the dough into a piping bag. Fill up to 2/3 of the hollows with it. Bake in a preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: see manufacturer) for approx. 10 minutes. In the meantime, put the piping bag in a cool place. Take the tray out of the oven. Let the mini cake rest in the tin for a short time, then turn out onto a cake rack.
Wash, dry, grease and dust with flour. Fill the dough into the hollows again and bake in the same way. Repeat the process until the dough is used up. Results in a total of about 3 trays. Dust the cakes with 3 tablespoons of icing sugar. Mini cakes keep well closed in a glass jar for several days.
