Brown the Butter: Start by placing your unsalted butter in a saucepan over low to medium heat. Stir continuously to make sure it doesn’t burn and watch closely for the brown bits that begin to form on the sides of the pan. Keep stirring until the butter turns a light golden brown and gives off a nutty aroma. Once it’s browned, remove the pan from the heat immediately and pour the butter into your mixing bowl. Let it cool for about 5 minutes.
Mix in Peanut Butter: Once the brown butter has cooled slightly, add the creamy peanut butter to the bowl. Stir the two together until they’re completely smooth and blended.
Add Brown Sugar: Mix in the one cup of light brown sugar with the butter and peanut butter. Stir well until the sugar is fully incorporated into the mixture.
Mash the Bananas: Peel the three overripe bananas into the bowl. Use a fork or potato masher to mash them thoroughly until they are mostly smooth with a few small chunks.
Add Egg and Vanilla Extract: Crack your egg into the bowl and add one teaspoon of vanilla extract. Mix these in with the banana mixture until everything is well combined.
Fold in the Dry Ingredients: In a separate bowl, whisk together your all-purpose flour, baking powder, and salt. Gradually fold the dry ingredients into the wet mixture. Mix gently until just combined.
Add Chocolate Chips: Once the dry ingredients are incorporated, add one cup of semi-sweet chocolate chips and fold them into the batter.
Prepare Your Baking Dish: Grease or line a 9×5-inch loaf pan with parchment paper. Pour the banana bread batter into the pan, spreading it out evenly.
Bake the Banana Bread: Pop your loaf pan into a preheated 350°F (175°C) oven. Bake for 55-65 minutes, checking with a toothpick inserted into the center.
Let it Cool: Once your peanut butter chocolate chip banana bread is done, remove it from the oven and allow it to cool in the pan for about 10 minutes before transferring it to a cooling rack. Let it cool for at least an hour before slicing.
Slice and Enjoy: Once cooled, slice up your peanut butter chocolate chip banana bread and enjoy.
