Banana Sour Cream Bread

3/4 c. butter
3 c. sugar
3 eggs
6 ripe bananas
1 (16 oz) sour cream
2 tsp. vanilla
2 tsp. cinnamon
1/2 tsp. salt
3 tsp. baking soda
4 1/2 c. flour

1/4 c. sugar
1 tsp. cinnamon

Preheat oven to 300 degrees. Grease 3 7x3inch loaf pans and dust them with a mixture of the 1/4 c. sugar and 1 tsp. cinnamon. Cream butter and sugar then mix in eggs, bananas, sour cream, vanilla, and cinnamon. Add salt, baking soda, and flour stir until well mixed. Bake 1 hour. I like to add chocolate chips to it too.
