Old-fashioned and comforting buttermilk banana bread is an ideal brunch treat or lunch box snack.

There’s nothing overly complicated or fancy about this recipe, it’s simply a way to use up bananas just before they go bad and turn them into something quite delicious.

Soft Bananas

Ideally, this recipe works best with bananas that are starting to go black and are soft.

Frozen bananas that have been completely thawed will also work. I often peel and freeze bananas for smoothies and this bread, honestly.


The buttermilk is what gives the loaf a bit of old-fashioned flavor. If you have some in a carton in the fridge use it here.

There are other options if buttermilk isn’t on hand. Sour regular milk by adding 3/4 teaspoons white vinegar to 4 Tablespoons milk and letting it sit for 10 minutes. Then measure out the 3 Tablespoons for the recipe.

The powdered, dry buttermilk works extremely well. Find this in the baking aisle of the grocery store. It’s a snap to have on hand and use.

Nuts are Optional

Banana nut bread is, of course, a classic. However, the nuts are not mandatory. Add them if you want, skip them if you don’t.

I would never run to the store just to get nuts for this bread. It is tasty with or without the nuts.

Make & Freeze Extras

Double or even triple the recipe if you have enough bananas on hand. Freeze the extras.

Simply place baked and cooled loaves into freezer bags and freeze. Thaw completely at room temperature to slice and serve.

Do eat up the frozen loaves within about 6 months to prevent freezer burn and preserve best flavor.
