Peanut Butter Banana Bread Recipe That’s Moist, Easy, and Packed with Flavor

There are few things better than the smell of banana bread baking in the oven, but adding peanut butter takes that cozy classic to a whole new level. This peanut butter banana bread is soft, rich, and full of warm homemade flavor, with just the right balance of sweet banana and creamy peanut butter in every bite.

It’s the kind of loaf that works any time of day. You can slice it for breakfast, serve it as an afternoon snack with coffee, or enjoy it as a simple dessert when you want something comforting but not overly complicated. If you’ve got a few overripe bananas on the counter and a jar of peanut butter in the pantry, you’re already halfway there.

Why I Love This Recipe

I love this recipe because it makes a familiar favorite feel new again without losing the comfort factor that makes banana bread so dependable. Peanut butter adds richness, extra moisture, and a slightly savory depth that keeps the loaf from tasting one-note sweet. It also makes each slice feel a little more satisfying.

Another reason this recipe is a keeper is how easy it is to make. You don’t need fancy equipment or hard-to-find ingredients, and the batter comes together quickly. It’s a great recipe for beginner bakers, but it’s also one of those dependable loaves experienced home cooks come back to again and again.

Ingredients

• 3 very ripe bananas, mashed
• 1/2 cup creamy peanut butter
• 1/2 cup unsalted butter, melted
• 3/4 cup brown sugar
• 2 large eggs
• 1 teaspoon vanilla extract
• 1 3/4 cups all-purpose flour
• 1 teaspoon baking soda
• 1/2 teaspoon baking powder
• 1/2 teaspoon salt
• 1/2 teaspoon cinnamon
• 1/2 cup milk
• 1/2 cup chocolate chips, optional
• Chopped peanuts for topping, optional

Swaps and Notes

Creamy peanut butter gives the smoothest texture, but crunchy peanut butter works too if you want a little extra bite. If your bananas are especially large, you may only need two and a half to three. The riper they are, the sweeter and more flavorful your bread will be.

You can swap the all-purpose flour for a one-to-one gluten-free baking blend if needed. For a slightly lighter sweetness, granulated sugar can replace some of the brown sugar, though brown sugar gives the loaf a softer, richer crumb.

Chocolate chips are optional, but they’re a great addition if you want a more dessert-like loaf. If you enjoy banana bakes with extra mix-ins, you’ll also love This Chocolate Chip Banana Bread Is My Favorite Way to Use Up Overripe Bananas.

How to Make Peanut Butter Banana Bread

1. Preheat the oven. Set your oven to 350°F and grease a standard 9×5-inch loaf pan or line it with parchment paper.
2. Mash the bananas. In a large mixing bowl, mash the ripe bananas until mostly smooth. A few small lumps are perfectly fine.
3. Mix the wet ingredients. Add the peanut butter, melted butter, brown sugar, eggs, vanilla extract, and milk. Whisk until the mixture is smooth and well combined.
4. Combine the dry ingredients. In a separate bowl, whisk together the flour, baking soda, baking powder, salt, and cinnamon.
5. Make the batter. Add the dry ingredients to the wet ingredients and stir gently until just combined. Do not overmix. Fold in the chocolate chips if using.
6. Transfer to the pan. Pour the batter into the prepared loaf pan and smooth the top. Sprinkle chopped peanuts over the top if you want a little crunch.
7. Bake. Bake for 50 to 60 minutes, or until a toothpick inserted in the center comes out with just a few moist crumbs.
8. Cool and slice. Let the bread cool in the pan for about 10 minutes, then transfer it to a wire rack to cool completely before slicing.

Tips for Success

Use very ripe bananas with lots of brown spots for the best flavor and natural sweetness. Underripe bananas won’t give you the same soft texture or depth.

Be careful not to overmix the batter once the flour goes in. Stir just until everything is incorporated. Overmixing can make the loaf dense instead of tender.

If the top starts browning too quickly in the oven, loosely tent the loaf with foil during the last 15 minutes of baking. Since peanut butter adds richness, this loaf can sometimes brown a bit faster than traditional banana bread.

For neat slices, let the bread cool fully before cutting. It’s tempting to dive in while it’s warm, but the texture improves as it sets.

This loaf also freezes beautifully. Wrap individual slices or the whole loaf tightly in plastic wrap and then foil, and freeze for up to 2 months. Thaw at room temperature or warm a slice in the microwave for a quick treat.

Leftover slices are especially good toasted. A warm slice with a little butter or peanut butter on top can easily pass for the best part of your morning.
