Banana Bread

My Favorite Go-To Banana Bread

1/2 c. shortening
3/4 c. sugar
1/2 c. brown sugar
2 eggs
1 t. vanilla
1 c. mashed, overripe banana
2 c. flour
1/2 t. baking soda
1/4 c. sour milk (I just put 2 t. vinegar into my measuring cup, then fill to 1/4 c. with milk--it curdles!)
1 t. salt
chopped nuts, optional

Cream shortening and sugars together. Stir in eggs, vanilla and banana. In separate bowl, mix flour and baking soda. Add dry ingredients to wet in halves or thirds, alternating with sour milk. Add nuts, if desired. Pour into greased large loaf pan, two small loaf pans, or 9x13 baking dish. Bake at 350° for 40-45 minutes for loaf pans, or  30-35 minutes for baking dish.
