Cream soft fat, 200 g sugar, 1 sachet vanilla sugar, bitter almond oil and salt. Add marzipan and stir well. Add the eggs one after the other, alternating with the cornflour and stir in.
Mix flour and baking powder and finally stir in briefly. Pour the dough into a greased, floured fat pan of the oven and smooth it down. Spread apricots and rhubarb on the dough and sprinkle with 50 g sugar and the remaining vanilla sugar.
