Our best basic banana bread is made with buttermilk! So easy to make 2 loaves with one recipe.
Preheat oven to 350 degrees. Grease and flour 2 medium size loaf pans.
Cream the butter and sugar together. Add eggs, and beat mixture until smooth.
Mash banana, add to the butter/sugar egg mixture. If the bananas are very soft, just add to the bowl, the paddle or beaters will mash the banana.
Mix in buttermilk until blended well. Turn off mixer.
Combine all of the dry ingredients into a bowl, and pour all at once into the wet mixture.
Fold together, just until wet and dry ingredients are incorporated. Don’t over mix. I use a large spoon or spatula for this step. No need to use the mixer. See notes.
Bake for 50 minutes to 1 hour, or until a toothpick inserted in the center of the loaf comes out clean.
