I’m a pro at buying bananas that no one eats. I’ll bet you are too. 😉

I act annoyed by it. I mean, why does everyone ask me for bananas if they’re just going to let them sit in the fruit bowl and rot?! But, let’s be honest – brown, mushy bananas make the best banana bread and I can’t be too upset about that.

Between our classic banana bread recipe, banana oatmeal cookies, and chocolate banana bread, there’s really no shortage of ways to use those bananas up.

That doesn’t stop me from coming up with new variations on banana bread though.

Take this Peanut Butter Banana Bread!

It’s chockfull of our favorite creamy peanut butter, which makes the bread super moist and extra flavorful. As always, we packed in as much peanut butter as possible – we always do when it comes to peanut butter recipes.

We like to spread slices of warm banana bread with even more peanut butter. It makes for a tasty breakfast or hearty afternoon snack.

Ingredients & Substitutions:

Ingredients for peanut butter banana bread recipe.

Bananas – Don’t throw away those brown, mushy bananas! They might look gross but they are sweet and easy to mash. That makes overly ripe bananas perfect for banana bread!

Peanut Butter – Grab your favorite brand of processed peanut butter, but I’d recommend sticking with the creamy variety. All natural peanut butter and chunky peanut butter may not work quite as well here. We like Skippy or Jif. Other types of processed nut butters (or sunbutter) should work well here.

Dry Ingredients – You’ll need some flour, baking soda, baking powder, white sugar, brown sugar, cinnamon, and salt! You may swap the white flour for half whole wheat flour, but the bread will not be quite as tender or moist.

Wet Ingredients – You’ll need a couple of large eggs, some vanilla extract, and sour cream. The sour cream adds lots of moisture to this bread. Swap the sour cream for fat free Greek yogurt for an extra protein boost.

How to Make Banana Bread with Peanut Butter:

Collage showing how to make peanut butter banana bread.

Cream: Add the butter and sugars to the large bowl and cream together with an electric hand mixer. It makes the job much simpler! Now beat in the peanut butter and sour cream until the mix is smooth and creamy.

Bananas: Next beat in the egg and vanilla extract until it is combined with the peanut butter mixture and then finally you can add in the mashed banana. Continue mixing until the peanut butter and banana mixture is well combined!

Combine: Add the dry ingredients to the peanut butter and banana mixture. Stir until the wet and dry ingredients are just combined. Don’t overmix or your banana bread will be tough.

Bake: When the peanut butter banana bread batter is ready you can pour it into a prepared 9×5 loaf pan and start baking! It’ll take about an hour or until a toothpick inserted in the center comes out clean. Let the bread cool in the pan for about 10 minutes before moving to a wire rack to finish cooling.

Banana Bread Mix-Ins!

Feel free to stir in up to one cup of nuts (peanuts, walnuts, pecans, etc.) or chocolate chips.

You always want to use the overly ripened brown bananas when making banana bread! It’s already mushy and is easy to mash, plus it’s even sweeter than a less ripe banana. It’s also a great way to use up those old bananas you were just going to throw out!
