This has been my favorite banana bread recipe since 1977.
This recipe is from the 1976 edition of the Favorite Recipes from Associated Women for Harding Cookbook, from Harding University.

Preheat to: 325 degrees

3 or 4 overripe bananas*
1 cup sugar
1 egg
1 1/2 cups flour
1/4 cup melted butter
1 tsp. baking soda
1 tsp. salt
1 tsp. baking powder
chopped nuts, optional

Mash bananas with fork.
Stir in other ingredients.
Pour into buttered loaf pan.
Bake at 325 degrees for 1 hour.

*Make sure your bananas are overripe, like pretty dark if not black.
If they aren't ripe enough they don't meld well with all the ingredients.
