This Buttermilk Banana Bread is the ultimate no-fuss recipe! With just a few simple ingredients, it comes together in minutes and bakes up perfectly moist every single time, thanks to the tangy richness of buttermilk.
Preheat the oven to 350°F. Spray a 9×5 loaf pan with nonstick baking spray. Set aside.You may also line the bottom and up the short sides with a strip of parchment paper to help easily remove the banana bread after baking. Spray again with baking spray.
In a medium bowl, mash the bananas with a fork, leaving them slightly lumpy. Set aside. (If using an electric hand mixer or stand mixer, you can add them to the sugar mixture below without mashing first, if desired)
In a large bowl stir together the butter and sugar. Mix in the eggs and vanilla and stir until smooth.
Add the buttermilk, mashed bananas, baking soda, and salt, and stir until blended.
Stir in the flour until just incorporated. Fold in the chopped walnuts or pecans if using.
Pour the batter into the prepared pan and bake for 50-60 minutes, or until a toothpick inserted in the center comes out mostly clean.
Cool in the pan for 15 minutes, and turn over carefully to cool on a wire rack.
Notes
Room Temperature: Store banana bread in an airtight container or tightly wrapped in plastic for 4-5 days. Keep in a cool, dry place, as humidity and warmth can cause the bread to mold.Refrigerator: Store in the refrigerator for up to 1 week to extend freshness; wrap tightly to prevent drying out.Freezer: Cool completely and freeze slices or the whole loaf by wrapping it in plastic wrap a couple of times and placing it in a labeled freezer-safe bag or container. It will keep well for 3 months. Thaw at room temperature or gently reheat slices in the microwave.
