For the curd tops, first prepare the dough. Beat the eggs with the sugar until foamy, add the milk and oil. Now stir in the flour and baking powder. Fill the dough into a pastry frame (approx. 20×30 cm) and bake at 180 °C for approx. 25 minutes.
For the filling, beat the yolks, sugar and lemon juice until foamy. First dissolve the gelatine in a little milk and then mix with the remaining milk. Now stir in the curd cheese and the milk-gelatine mixture. Beat the egg whites until stiff, also whip the whipped cream. Finally, fold in the beaten egg whites and whipped cream.
Cut the cooled cake in half, put the frame back over the bottom part, spread the filling on top and put the top part on top. Refrigerate the curd tops for about 4 hours, preferably overnight.
