You need
3 ripe bananas
125 ml sun flour oil
2 eggs
250 gr plain flour
100 g2 caster sugar
half tsp bicarbonate of soda
1 tsp baking powder
Mash the bananas. Mix the eggs and the oil by beating them together with a fork. Add the sugar. Separately mix the flour, bicarb and baking powder and add this mixture to the eggs, sugar and oil one. Beat lightly still with a fork. Add the bananas. Pour it all into a greased (with a bit of extra sun flour oil) round tin and bake it in a preheated over at 200 degrees for 35-40 minutes.
Children like mashing the bananas and beating with the fork. The cake is not dense, so if you let the kids icing it keep an eye on them or you will end up with more icing and sprinkles than cake itself.
