The base: Beat the eggs with the sugar and add the flour with baking powder, pour onto a tray - 30h37 cm - littered with baking paper and bake 20 minutes at 200C or until ready. Once it is ready, cut into 2 and the middle smeared with banana cream. Top smeared with strawberry jam, then put the banana and sprinkle with the chocolate spread. For the cream the butter put in a saucepan on medium heat and melt, add flour. Stir a few seconds until the mixture is homogenous and then sipvam milk reconstituted therein vanilla. Again wrong to not burn and add the beaten egg - pour a stream and after a minute and put sugar to poraztopi. Then pureed banana put until the cream is still on the stove (can put 1 banana, maybe more, as you see). After 5 minutes, clean off all grease from the heat and the base.
