Baking: Buttermilk Bannana Bread

This recipe make 2 large loaves. It was gone in no time.
I freeze overripe bananas and use often for smoothies but I found out that they are great to have on hand to use in banana bread.

1/2 cup butter softened- 1 stick
1 cup white sugar
4 eggs
4 very ripe bananas, mashed
1 cup buttermilk
2 tsp pure vanilla extract
4 cups flour
4 tsp baking soda
1 tsp cinnamon
1 tsp salt

Preheat oven to 350 degrees. Cream together the butter and sugar. Add the eggs and mix well. Add the remaining ingredients and mix well.
Pour into 2 well greased bread loaf pans. Bake for 1 hour at 350 degrees and let cool slightly before removing from the pans and cooling on a wire rack.
