Make shortcrust pastry out of the flour, butter, curd cheese, baking powder, salt, vanilla sugar and the rest of the sugar. Roll out half of the pastry on a floured cloth, but not too thinly. Spread half of the apple mixture on the shortcrust pastry, fold in the sides and roll over with the help of the cloth.
