In a bowl, peel the bananas, slice and mash well.
Add the flours, sugar, salt and knead to a smooth dough. Since the banana will be very sticky, you will have to add the flours slowly and knead to get the mixture come together as a dough.
Rest for 10 mins, then pinch out small pieces, and shape into walnut-sized balls.
Heat cooking oil to a pan. Add the banana fritters and cook, turning frequently, for about 5 minutes or until nicely browned and cooked through.
Drain on kitchen paper and serve either hot or cold with chocolate sauce.
