We love peanut butter around here. Whether it’s the classic PB&J combination in my peanut butter and jelly bars or mixed with chocolate in peanut butter cup cookies or peanut butter cup brownies, my family loves it all.

We’ve been on a big banana bread kick lately, so it just made sense to combine our love for peanut butter with our banana bread obsession. The result is a peanut butter banana bread that we all devoured immediately.

Rich and flavorful peanut butter banana bread

I have a rule when it comes to the recipes I share: If I am going to mention an ingredient in the recipe title, you need to be able to taste that ingredient in the final dish.

I just think that’s what I owe to you guys, ok?

So if I was going to make peanut butter banana bread, I wanted to make sure you could taste the peanut butter in every bite of the bread. 

I’ve noticed that a lot of peanut butter banana bread recipes use just ½ cup of peanut butter in the batter, but that wasn’t quite enough for me. It gave a hint of peanut butter, but I wanted a bolder peanut butter flavor.

My version uses ¾ cup of peanut butter in the batter, with another 2 tablespoons swirled into the top of the bread. It gives this bread a rich flavor that pairs perfectly with the sweet bananas.

Plus, the peanut butter adds a little extra protein to each slice, making it a more filling after-school snack than Dominique Ansel’s banana bread. Pair it with a chunky monkey smoothie or a banana, peanut butter, and date smoothie for a really filling snack!

For more PB and banana goodness, try peanut butter and chocolate banana muffins or peanut butter banana chocolate chip granola bars.

How to make peanut butter banana bread

This recipe is based on my oatmeal banana bread, so it’s easy to make and you can get it in the oven in a matter of just a few minutes.

Ingredients you’ll need

To make my peanut butter banana bread, you will need:

• 1 ½ cups mashed ripe bananas (from about 3 bananas)
• 3/4 cup creamy peanut butter, plus 2 tablespoons for the top
• 1/2 cup granulated sugar
• ½ cup lightly packed light brown sugar
• ½ cup vegetable oil
• 2 large eggs
• 2 teaspoons pure vanilla extract
• 1 3/4 cups all-purpose flour
• 1 teaspoon baking powder
• ½  teaspoon baking soda
• ¾ teaspoon kosher salt

I prefer using creamy peanut butter for this bread, but you could use crunchy peanut butter if you want some added crunch in the banana bread. I would still recommend using creamy peanut butter for the swirl on the top of the loaf, though.

If you run out of brown sugar, don’t panic. You can make a simple brown sugar substitute to use in this recipe instead. 

And if your brown sugar hardened in the pantry, check out my tips for how to soften brown sugar and save yourself a trip to the grocery store. 

Making this bread

To make this peanut butter banana bread, start by mixing the mashed bananas with the peanut butter, sugars, oil, eggs, and vanilla with a mixer until well combined. 

In a separate bowl, whisk together the dry ingredients: flour, baking powder, baking soda, and salt.

Stir the dry ingredients into the banana mixture until just combined and pour the batter into a parchment-lined 9×5-inch loaf pan. 

Now it’s time to add the peanut butter swirl to the top of the bread. If your peanut butter is really thick, microwave it for a few seconds to loosen it up – 10-15 seconds should do the trick.

Drizzle the 2 tablespoons of peanut butter over the top of the batter and use a skewer or chopstick to swirl it into the top of the bread.

Bake the bread at 350°F for 70-75 minutes, or until a toothpick inserted into the center comes out clean. Check the bread around the 60-minute mark; if the top is deeply golden, tent the top loosely with foil to prevent it from getting too dark.

Let the peanut butter banana bread cool in the pan for about 10 minutes before removing it to a wire rack to finish cooling.

Store your peanut butter banana bread at room temperature, well wrapped in foil, for up to 3 days. You could also extend its shelf life by storing it in the refrigerator for up to 5 days or freezing for 1-2 months.
