Peanut Butter Banana Bread

Peanut Butter Banana Bread

A combination as classic as peanut butter and banana should be savored, and that is exactly what you’ll do when you make this recipe. One of the best things about this recipe is the endless variations, like chocolate chips, walnuts, rendered bacon, and even banana chips.

The step of mashing the bananas and storing them in a sealed jar for 24 hours may seem weird, but this adds a slightly sour flavor to the end result. The bananas will begin to ferment a bit, developing an even stronger banana flavor that will complement the peanut butter well. However, if you’re short on time you can skip this step.

If you are feeling really decadent you can grill the sliced peanut butter and banana bread in butter, then top with sliced bananas and honey for a rich and delicious evening treat. Or, go the lighter route and serve with fresh berries and a small drizzle of maple syrup. Either way you serve this bread, it’s sure to impress and bring joy to everyone you know. 

“I loved this twist on the regular banana bread – already full of banana flavor, the peanut butter reminded me of the infamous Elvis sandwich. Maybe next time I will serve it for brunch with some crispy bacon for the ultimate treat!” —Tracy Wilk

  2. Position a rack in the center of the oven and heat to 350 F. Spray a standard 8×4-inch loaf pan with cooking spray and line with a parchment paper sling (letting some of the parchment hang over the opposite sides will help you pull the loaf out of the pan after baking).
