This is my husband's grandmother's recipe for banana bread.
It's my favorite. It's super easy to tweak - I substituted the tangerine jam for the bananas.
1 1/2 cup sugar
1/2 cup butter
1 tsp vanilla
1/2 cup buttermilk (I just sour skim milk with a dash of vinegar)
2 cups flour
1 tsp baking soda
1/2 tsp baking powder
1 cup mashed bananas
Grease pans, bake at 325 for 40-50 minutes.
