Knead the dough ingredients and press them into a greased springform pan. Press the edge quite high.
Mix the ingredients for the filling together (attention: the filling is very runny!) And also place in the springform pan.
Bake this at 175 ° for about 45 minutes.
In the meantime, beat the egg whites with the sugar until stiff, spread them on the cake after the baking time and bake again at 175 ° for approx. 15 minutes.
