Step‑by‑Step Instructions for Peanut Butter Banana Bread
Step 1: Preheat the Oven
Start by preheating your oven to 350°F (175°C). While it's warming, generously grease a 9" x 5" loaf pan to ensure your Peanut Butter Banana Bread releases easily after baking. This preparation step is crucial for a perfect loaf, so don't skip it!
Step 2: Mix the Dry Ingredients
In a medium bowl, whisk together 1 ½ cups of all-purpose flour, 1 teaspoon of ground cinnamon, 1 teaspoon of baking powder, ½ teaspoon of baking soda, and ½ teaspoon of salt until well combined. This step helps distribute the leavening agents evenly, ensuring a consistent rise throughout the bread.
Step 3: Cream the Wet Ingredients
In a large mixing bowl, beat together ½ cup of unsalted butter, ¾ cup of light brown sugar, and ½ cup of creamy peanut butter using an electric mixer. Mix until the mixture is light and fluffy, which should take about 3 minutes. Next, add 2 large eggs one at a time, mixing until each is fully incorporated, and then blend in 1 teaspoon of vanilla extract.
Step 4: Combine the Mixtures
Gradually add the dry ingredients to the wet mixture, alternating with ½ cup of sour cream. Start and end with the dry mixture, mixing just until combined. This helps prevent overmixing, which can lead to a dense loaf of Peanut Butter Banana Bread. Be gentle to keep the batter light and airy.
Step 5: Add Bananas and Nuts
Now it’s time for the star ingredient! Gently fold in 1 cup of mashed overripe bananas and optional ½ cup of chopped nuts, such as walnuts or pecans, until evenly distributed. Take care not to overwork the batter; the goal is to have just enough blending for a well-combined mixture.
Step 6: Bake the Bread
Pour the batter into your prepared loaf pan, smoothing the top gently with a spatula. Place it in the preheated oven and bake for 50-55 minutes, or until the top is golden brown and a toothpick inserted into the center comes out clean. The delightful aroma will fill your kitchen!
Step 7: Cool the Bread
Once baked, remove the Peanut Butter Banana Bread from the oven and let it cool in the pan for about 10 minutes. This allows it to set a bit before transferring. Carefully turn it out onto a wire rack to cool completely, so it retains its moist texture and can be sliced easily.

Make Ahead Options
These Peanut Butter Banana Bread preparations are perfect for busy home cooks looking to save time! You can mash your bananas and mix your dry ingredients (flour, baking powder, baking soda, cinnamon, and salt) up to 24 hours in advance, storing them separately in airtight containers in the refrigerator. Additionally, you can cream the butter, peanut butter, and sugars, along with the eggs and vanilla, and keep this mixture covered in the fridge for the same duration. When you're ready to bake, simply combine the mixtures and fold in the bananas and nuts, then bake as directed. This way, your homemade Peanut Butter Banana Bread will be just as delicious and moisture-rich as if you made it from scratch that day!

Expert Tips for Peanut Butter Banana Bread
- Banana Quality: Use overripe bananas for the best sweetness and moisture. They should have brown spots to ensure maximum flavor.
- Avoid Overmixing: Be careful not to overmix the batter when combining wet and dry ingredients; this ensures your Peanut Butter Banana Bread remains tender and fluffy.
- Check Freshness: Always use fresh baking powder and baking soda for optimal rise—old leavening agents can lead to a dense loaf.

- Cool Properly: Let the bread cool in the pan before transferring it to a wire rack, which helps maintain its moist texture.

Peanut Butter Banana Bread Recipe FAQs
What type of bananas should I use for the best flavor?
Absolutely! Opt for overripe bananas with plenty of brown spots. They are sweeter and lend a lovely moisture to the bread, enhancing its overall flavor. Aim for 3-4 medium bananas for this recipe to achieve that beautiful taste and texture!
How should I store leftover Peanut Butter Banana Bread?
To keep your delicious Peanut Butter Banana Bread fresh, store it in an airtight container at room temperature for up to 3-4 days. If you prefer a slightly longer shelf life, you can refrigerate it for about a week, although it may lose a bit of moisture.
Can I freeze Peanut Butter Banana Bread?
Yes! To freeze your Peanut Butter Banana Bread, slice the loaf first for convenience. Wrap each slice tightly in plastic wrap, followed by aluminum foil, to protect it from freezer burn. It will keep well in the freezer for up to 3 months. When you're ready to enjoy it, simply thaw overnight in the fridge and reheat as desired.
What should I do if my banana bread doesn't rise?
Very good question! If your loaf doesn’t rise as expected, first check the freshness of your baking powder and baking soda, as expired agents can result in a dense loaf. Ensure that you're mixing the wet and dry ingredients gently and not overmixing the batter, which can also hinder rise.
Is this recipe safe for people with nut allergies?
If you or your loved ones have nut allergies, you can still enjoy a variation! Simply omit the creamy peanut butter and use sunflower seed butter instead. This will give you a similar texture without the nuts. Just be sure to check all other ingredients for potential allergens.
How do I know when my Peanut Butter Banana Bread is done baking?
The best way to check doneness is by inserting a toothpick into the center of the loaf. If it comes out clean or with just a few moist crumbs, your bread is ready! The top should also be a beautiful golden brown, adding a delightful visual cue that it’s baked to perfection.
