How to Make It

Let’s get baking your delicious Peanut Butter Banana Bread!

Preheat the oven

Preheat oven to 350°F (175°C) and grease a 9" x 5" loaf pan. If preferred, line it first with parchment paper for easy removal later.

Whisk dry ingredients

In a mixing bowl, whisk together the flour, cinnamon, baking powder, baking soda, and salt until well combined. Set aside for later use.

Beat wet ingredients

Using an electric mixer on medium speed, beat the softened butter, brown sugar, and peanut butter together until the mixture is fluffy and well blended.

Add eggs and vanilla

Add the eggs to the bowl one at a time, mixing well after each addition. Then, mix in the vanilla extract until fully incorporated.

Combine mixtures

Reduce the mixer speed to low. Add the flour mixture in three portions, alternating with the sour cream in two portions, mixing until just combined after each addition.

Stir in bananas and nuts

Gently stir in the mashed bananas until they are evenly distributed throughout the batter. If desired, fold in the chopped nuts.

Bake the bread

Spread the batter evenly in your prepared loaf pan. Bake for 50 to 55 minutes, or until the bread is golden brown and a toothpick inserted into the center comes out clean.

Cool the bread

Allow the bread to cool in the pan on a wire rack for 10 minutes. Carefully transfer the bread from the pan to the wire rack to cool completely before slicing.

How to Store It

Fridge: Store in an airtight container for up to 5 days.
Freezer: Yes, it freezes well for up to 3 months.
Reheat: Microwave slices for 15-20 seconds or toast in the oven.

Tips for Best Results

• Ensure your bananas are very ripe for maximum sweetness and moisture.
• Don’t overmix the batter; stop mixing as soon as the dry ingredients are incorporated.
• Let the bread rest completely before slicing for cleaner pieces.
• For best flavor, enjoy slices at room temperature or lightly toasted.

Serving Suggestions

• Serve with a spread of extra peanut butter for a protein-packed snack.
• Pair with a scoop of vanilla ice cream for a delicious dessert treat.
• Enjoy alongside a cup of coffee or tea during breakfast or brunch.
