Grease a fat pan of the oven (approx. 32 x 39 cm) and dust with flour. Preheat the oven (electric stove: 175 °C/circulating air: 150 °C/gas: see manufacturer). For the dough, wash lemons hot, dab dry and rub the peel.
Cream 400 g butter, sugar, vanilla sugar and 1 pinch of salt with the whisks of the mixer. Stir in lemon zest. Stir in the eggs one by one. Mix 500 g flour and baking powder and stir in.
Put the dough into the fat pan and smooth it down. Bake in the oven for about 25 minutes. Squeeze 1 lemon. Stir with 25 g icing sugar until smooth. Remove the cake from the oven and sprinkle with lemon icing. Let it cool down.
For the face, briefly stir cream cheese and 225 g icing sugar with the whisk of the mixer until smooth. Colour the cream with green and a little blue food colouring. For the eyes, lightly press in white chocolate kisses so that the chocolate tears slightly.
Stir a little red food coloring with water until liquid and dribble it into the cracks of the chocolate kisses. Press the chocolate lentils in the middle.
Cut the cake plate in half crosswise. Place each cake on a board or tray and set aside about 4 tbsp. of green cream. Spread each cake with half of the rest of the cream in a wrinkled pattern. For the noses, cut the sponge fingers in half crossways, spread a little cream on them and place them in the middle of the cakes.
Spread 4 dark chocolate kisses with the rest of the cream and place them as ears on the top of the cakes. Place chocolate eyes on the cakes.
For the hair, cut licorice sticks into pieces of different lengths and spread them on top of the cakes. Place 1 strawberry string as mouth on each cake. Place 4 dark chocolate kisses on the bottom of the sides of the cakes as screws.
Paint the scar and nostrils with sugar writing. Attach the remaining strawberry and liquorice strings as wires to the top of the cakes.
