Peanut Butter Banana Bread transforms overripe bananas into your new favorite treat – moist, flavorful, and packed with creamy peanut butter goodness. This easy one-bowl recipe delivers a loaf that’s tender and rich, perfect for breakfast, snacks, or dessert. You’ll love how simple it is to make with pantry staples.
Why This Recipe Stands Out
This peanut butter banana bread stays ultra-moist thanks to the natural oils in peanut butter and ripe bananas. The flavor deepens overnight, making each slice even better the next day. Customize it with chocolate chips or keep it pure peanut butter – either way, it beats ordinary banana bread every time.
Ingredients
Gather these simple ingredients for one 9×5-inch loaf (about 12 slices).
| Ingredient | Amount | Notes |
|---|---|---|
| Ripe bananas (mashed) | 1 cup (3 medium) | Use brown, spotty bananas for maximum sweetness |
| Creamy peanut butter | 1/2 cup | Natural or regular; stir well if separated |
| Unsalted butter (melted) | 1/4 cup | Or coconut oil for dairy-free |
| Light brown sugar (packed) | 3/4 cup | Adds moisture and chew |
| Large egg (room temperature) | 1 | For binding and lift |
| Vanilla extract | 1 tsp | Pure for best flavor |
| All-purpose flour | 1 1/2 cups | Spooned and leveled; gluten-free 1:1 blend works |
| Baking soda | 1 tsp | Key leavener |
| Kosher salt | 1/2 tsp | Balances sweetness |
| Chocolate chips (optional) | 1 cup | Semi-sweet or peanut butter chips |
Step-by-Step Instructions
Follow these numbered steps for foolproof results. Prep time: 15 minutes. Bake time: 50-65 minutes.
- Preheat oven to 350°F (175°C). Grease a 9×5-inch light-colored loaf pan or line with parchment paper overhanging the sides for easy removal.
- In a large bowl, mash bananas until smooth. Stir in peanut butter and melted butter until fully combined.
- Add brown sugar, egg, and vanilla. Whisk until smooth and creamy – no lumps remain.
- In a medium bowl, whisk flour, baking soda, and salt.
- Gently fold dry ingredients into wet just until combined. Avoid overmixing to keep the texture tender.
- Fold in chocolate chips if using. The batter will be thick.
- Spread evenly into prepared pan. Bake 50-65 minutes, tenting with foil after 45 minutes if tops browns too fast. A toothpick inserted in center should come out clean or with moist crumbs.
- Cool in pan 10 minutes, then transfer to wire rack. Cool completely before slicing for best peanut butter flavor.
Expert Tips for Success
- Ripe bananas matter: The browner, the sweeter and more moist your bread.
- Room temperature egg mixes smoothly; cold ones can cause lumps.
- Check at 50 minutes – ovens vary. Internal temp should hit 195-200°F for doneness.
- Flavor peaks day two: Wrap and wait if you can resist.
- High altitude? Reduce baking soda to 3/4 tsp and bake at 340°F.
- Troubleshooting: Sunken middle means overmixing or underbaking; gooey center needs more time.
Storage and Freezing
Keep your loaf fresh with these simple methods.
- Room temperature: Wrap tightly in plastic; lasts 2-3 days.
- Refrigerator: Up to 1 week in airtight container; warm slices before eating.
- Freezer: Cool completely, wrap in plastic then foil, or slice and bag individually. Freeze up to 3 months; thaw overnight.
