1/2 c. whole wheat flour
1 1/2 c. oat bran cereal
1/2 c. sugar
2 tsp. baking powder
1 tsp. baking soda
1/2 tsp. salt
1/4 c. buttermilk
3 med. very ripe bananas, mashed
1/4 c. safflower oil
1 tsp. vanilla
4 egg whites
1/4 c. walnuts (opt.)

Combine whole wheat flour, oat bran cereal, sugar, baking powder, baking soda, salt in a small bowl. Combine buttermilk, mashed bananas, safflower oil, vanilla and egg whites in a large bowl. Add dry ingredients to wet and mix well. Stir in walnuts. Place in a greased and floured 5 x 9 inch loaf pan. Bake at 350 degrees for about 1 hour or until done.

I prefer to use powdered buttermilk (which is lower in fat). You can add the powdered buttermilk to the dry ingredients and add 1/4 cup of water or skim milk to the wet ingredients.
