Preheat oven to 350 degrees. Spray two loaf pans with non-stick cooking spray. Set aside.

Cream butter, sugar and eggs in a large bowl with electric mixer. In a separate bowl, mix flour, baking soda, baking powder and salt. Add the flour mixture to the butter mixture and mix on low. Add in the mashed bananas, buttermilk and vanilla. Mix well. Pour batter evenly into the two greased loaf pans. Bake in oven at 350-degrees for 50 minutes or until toothpick inserted in center comes out clean. Let cool completely before attempting to remove from pans. Slice when cool and enjoy!

*I use powdered buttermilk mixed according to the package directions in place of fresh buttermilk.
