This recipe works for both muffins and loaves. I try to always have a few ripe bananas on hand in the freezer. A little tip for for freezer bananas is to peel them before you freeze them.
Yield: 1 loaf or 12 muffins
3/4 Cups sugar
1/4 cup butter
1 egg
1/2 tsp vanilla
1/2 cup ripe banana mashed
1/3 cup sour milk (1/3 cup milk + 1 Tbsp lemon juice)
1/2 tsp baking soda
1 cup flour
1/2 tsp baking powder
1/2 cup chocolate chips
