Preheat oven to 350℉. In a small bowl combine flour, baking soda, baking powder, salt and set aside. In a large bowl whisk together sugar and oil. Beat in one egg at a time until well combined. Stir in mashed bananas, orange juice and vanilla. Add flour mixture and stir until just combined. Pour into a 9x5x2.75″ loaf pan sprayed with non stick spray or greased and floured. Bake for approximately 60 minutes or until a toothpick inserted comes out clean. Cool completely on a wire rack prior to removing from pan. Enjoy!
