This easy banana nut bread with just the right amount of very ripe bananas comes out moist, sweet, and flavorful every time! If you have spotty bananas lying around, this great recipe is for you.
Preheat the oven to 325 degrees. Grease a light-colored loaf pan (8 1/2″ x 4 1/2″ x 2 3/4” high) with non-stick cooking spray and set aside.
In a large bowl, mix oil, butter, and granulated sugar until well combined. Stir in other wet ingredients - eggs, pure vanilla extract, and mashed banana until smooth.
Gently stir in dry ingredients and buttermilk until a uniform batter has formed. Scrape sides to ensure no lumps are present. Stir in 1/2 cup of chopped walnuts. Pour into a prepared pan and top with the remaining 1/4 cup of chopped nuts.
Bake for 50 to 60 minutes in the lower half of the oven or until completely baked. Remove from the oven and cool for at least 15 minutes before removing from the pan. Slice and serve.
