Which is why this recipe is for banana muffins and not banana bread.
Mix in a bowl:
1 really ripe banana, mushed with a fork
1 egg, beaten
1/4 c. oil
1 t. vanilla
1/2 t. vinegar
1/4 c. brown sugar
3/4 c. gf flour
1/2 t. cinnamon
1/2 t. baking powder
1/2 t. baking soda
1/2 t. salt
Pour into a greased muffin tin and bake for 20 minutes at 350. Top with nuts, seeds, chocolate, or nothing. I couldn't make up my mind so I did a couple of each.
Makes 6 muffins.
