Chop 100 g chocolate coating. Cream the fat, 225 g sugar, vanillin sugar and 1 pinch of salt with the whisks of the hand mixer. Stir in the eggs one by one. Mix flour, baking powder and couverture and stir into the mixture alternately with the banana juice. Spread the mixture on the greased fat pan of the oven and smooth it down. Peel the bananas and cut them in half lengthwise.
Place 3 halves in each case to a cross stripe, altogether 6 strips. Spread bananas generously with lemon juice.

Pour cream into a piping bag with a star-shaped spout and squirt onto the cake between the banana strips.
