Puree the bananas and then mix with the sugar and flour to form a dough.
Heat the oil in a deep fryer. It is hot enough when no more bubbles appear on a wooden wooden spoon dipped in hot oil.
Then add the banana dough teaspoon by spoon to the hot oil and bake for about 2 minutes until golden yellow. Remove the banana balls and drain them on kitchen paper.
If you like, the banana balls can also be sprinkled with desiccated coconut.
