Peanut Butter Banana Bread

I absolutely love banana bread, and today I have made it even better with peanut butter!

This banana bread is moist and dense, loaded with peanut butter and bananas, and is bursting with flavour.

Made from 4 large ripe bananas, this recipe produces the most tender and flavourful crumb. More bananas = more moisture and more flavour.

Drizzle extra peanut butter on top of the batter and swirl it in before baking for extra PB goodness!

Peanut Butter Banana Bread
  • Plain/all-purpose flour: The base of the bread, providing structure and a tender crumb.
  • Baking soda: Acts as the leavening agent, helping the bread rise and stay light.
  • Salt: Enhances flavour and balances the sweetness of the bananas and sugar.
  • Large eggs: Bind the ingredients together and add richness to the batter.
  • Light brown sugar: Adds sweetness with a hint of molasses flavour that pairs well with banana and peanut butter.
  • Greek-style yogurt: Keeps the bread moist and tender.
  • Vegetable oil: Adds moisture and helps create a soft, moist texture.
  • Vanilla extract: Enhances the overall flavour.
  • Bananas: The star ingredient—adds natural sweetness, moisture, and classic banana flavour.
  • Smooth peanut butter: Adds richness, a nutty depth of flavour, and a creamy texture that sets this banana bread apart from the rest.

How to make

Peanut Butter Banana Bread

Mixing dry ingredients: In a medium bowl, whisk together the flour, baking soda, and salt. Set aside.

Mixing wet ingredients: In a separate large bowl, whisk together the eggs and sugar until thick and lighter in colour. Add the yogurt, oil, vanilla, bananas, and peanut butter, and whisk until combined.

Mixing the two: Add the dry ingredients in thirds and fold in until just combined – do not overmix.

Pour into a pan: Pour the batter into a prepared loaf pan and spread out evenly.

Optional: Drizzle 2 tablespoons of peanut butter over the top of the batter. (If your peanut butter is too thick to drizzle, microwave it for a few seconds until runny.) Use a knife or toothpick/cake tester to swirl the peanut butter into the top of the batter.

Bake for about 60 – 70 minutes, or until a toothpick/cake tester inserted into the centre comes out clean with a few moist crumbs.

  • Greek-style yogurt: Sour cream, plain yogurt, or buttermilk can be used in place of Greek yogurt to keep the bread moist and tender.
  • Vegetable oil: Both melted butter and coconut oil will work well, adding richness. Coconut oil may give a slight coconut flavour.
  • Light brown sugar: White sugar works in a pinch, though it won’t have the same caramel-like depth. Coconut sugar adds a similar warm flavour.
  • Peanut butter: You can swap in any nut or seed butter depending on your preference or dietary needs.
  • Eggs: For each egg, use 1 tablespoon ground flaxseed + 2.5 tablespoons water, or 1/4 cup (63g) unsweetened applesauce.
  • Add-ins: Stir in 1/2 to 1 cup of chocolate chips for a richer, more indulgent loaf. Or add chopped peanuts, walnuts, or pecans for crunch and texture.

Recipe FAQs

Can I use natural peanut butter?

Yes, but make sure it’s well-stirred and not too oily or runny, as it can affect the texture. A thicker natural peanut butter works best.

Can I make this banana bread gluten-free?

Absolutely! Use a 1:1 gluten-free flour blend. The texture may vary slightly, but it still bakes up moist and delicious.

Can I use crunchy peanut butter?

Yes! Crunchy peanut butter adds a nice texture and extra peanut pieces throughout the loaf.

Can I add mix-ins like chocolate chips or nuts?

Definitely. Chocolate chips, chopped peanuts, or even swirls of extra peanut butter make great additions.

How ripe should my bananas be?

The riper, the better—look for bananas with lots of brown spots. They’re sweeter and mash easily, which helps flavour and texture.

Can I use almond butter or another nut butter instead?

Yes, you can substitute with almond butter, cashew butter, or even sunflower seed butter for a nut-free version.

Can I turn this into muffins?

Absolutely! Spoon the batter into a lined muffin pan and bake at the same temperature for 15 – 20 minutes, or until a toothpick inserted comes out clean.
