Simply perfect banana bread that stays moist and delicious for days thanks to the addition of buttermilk. This recipe was passed to me from my mother, AKA Nana, and has been enjoyed by my family for over 40 years.
Preheat oven to 350°. Grease the bottom of a 9x13 baking dish with baking spray. Set aside.
In a stand mixer (or whisk by hand), cream together butter, sugar, and eggs until light and fluffy. Add mashed bananas and stir to combine.
In a small bowl, combine flour, baking soda, and baking powder.
Alternately add a little of the flour mixture and a little of the buttermilk to the batter until everything is combined well.
Pour batter into prepared baking dish and spread evenly. Bake for 30-40 minutes or until golden brown and toothpick inserted comes out clean.
Notes
If you do not have buttermilk, you can substitute with one cup of milk mixed with one teaspoon white vinegar. Let sit for a few minutes before adding to batter.
