Beat eggs and sugar until frothy. Add the oil. Then alternately add the flour mixed with the baking powder and the milk. Add the nuts, dissolved chocolate and vanilla sugar and stir everything well.
Put the runny dough on a greased baking sheet dusted with flour. Bake at approx. 200-220 ° C for about 30-40 minutes - it always depends on the oven. Remove the cake when it turns brown.
