Yummy Banana Bread

1/2 cup butter (room temp.)
1 cup sugar
2 eggs
1 tsp. vanilla
1 1/2 cups flour
1 tsp. baking soda
1/2 tsp. salt
1 cup mashed bananas (use very ripe ones)
1/2 cup chopped nuts
1/2 cup sour cream
1 tsp. cinnamon

Preheat oven to 350 degrees. In a large bowl cream the butter and sugar. Beat in eggs and vanilla. Add bananas, nuts and sour cream. Mix well. In a separate bowl, mix all dry ingredients. Pour the dry ingredients into the wet ones and fold them together gently just until all moistened. Bake in a greased loaf pan for 1 hour or 4 mini-loaf pans for 45 minutes. Enjoy!
