Beat the eggs and sugar until creamy. Using a wooden spoon, carefully fold in the flour and wheat powder. Then pour the mixture into a piping bag with a large nozzle and pipe the mixture onto a paper the size of the bananas. Bake at 180 degrees for 10 minutes. When cool, remove from paper.
Whip butter until creamy and fold in vanilla pudding. Pipe the buttercream on the sponge sheets and place half a banana on each. Chill in the refrigerator for 10 minutes.
In the meantime, heat the whipping cream and melt the cooking chocolate in a water bath. Add the whipped cream to the cooking chocolate and stir. Dip the bananas into the lukewarm chocolate with a fork or coat the bananas with chocolate.
