Prepare the banana bread

Preheat the oven to 350 degrees F. Coat a 9×5-inch loaf pan with vegetable cooking spray. Set aside.

In a large mixing bowl whisk together the flour, baking soda, salt, cinnamon and allspice.

Next combine the melted butter, sour cream and peanut butter in a small bowl. Whisk until blended then add the eggs, vanilla, granulated sugar and brown sugar. Whisk until smooth with no chunks of brown sugar remaining.

Mash the bananas until smooth then add to the flour mixture. Pour in the sour cream mixture then fold together using a spatula until combined. Gently fold in the chopped peanuts but don’t over-mix!

Pour the batter into the prepared loaf pan and bake for 60 to 70 minutes.

Prepare the peanut butter glaze

Whisk together the glaze ingredients until smooth. Add additional powdered sugar as needed to reach the desired consistency. Pour, drizzle or spoon the glaze over the Peanut Butter Banana Bread then top with chopped peanuts.

Tips for the best Peanut Butter Banana Bread

The first tip for making great banana bread is to use extremely ripe, almost black bananas. Mash them until no puffy chunks remain before mixing into the batter.

Next, take care that you don’t overmix the batter. You’ll get a better rise if you make this by hand instead of using an electric mixer.

This recipe calls for a little ground cinnamon and allspice. Don’t skip adding these warm spices as they compliment the peanut butter beautifully. You can’t really taste them but It just works and enhances the flavor of the bread.

Use regular brands of peanut butter like Jif, Peter Pan or Skippy. Do not use all-natural peanut butter which can be oily.

Finally, check the bread often to ensure it doesn’t over-bake. The finished bread should be moist and tender, not dry and crispy. If using a dark or a ceramic loaf pan reduce the oven temperature to 325 degrees F.

Storing Peanut Butter Banana Bread

Once glazed you can leave the banana bread out at room temperature for up to 1 day. For longer storage, seal in an airtight container and refrigerate for up to 5 days.

Variations and add-ins

Turn this Peanut Butter Banana Bread into an ode to Elvis by adding mini-chocolate chips to the batter, a sprinkling on top before baking and then even more mini-chips over the glaze. So good!

For more intense peanut butter flavor add peanut butter chips to the batter. What a treat!

Make ahead and freezing

If you want to make the bread ahead of time, skip adding the glaze until ready to serve. Wrap the bread in plastic wrap or seal in an airtight container and keep at room temperature until ready to serve.

If planning to freeze the entire loaf, omit the glaze until you plan to serve. Thaw overnight in the refrigerator then leave at room temperature for 1 hour before serving.

Leftover slices can be frozen with the glaze if desired.
