Roll out the dough for a round cake tray (diameter 28 cm). Grease the tray, cover it and prick the cake dough.
Mix all other ingredients to a thick batter and spread over the cake batter. Bake in a hot oven at 180 °C for about 30 minutes.
Make a silhouette of your choice from a paper, place it on the finished cake and sprinkle with the powdered sugar. Remove the silhouette – done.
