These easy-to-make Peanut Butter Banana Brownies are delightfully chewy with a crispy topping and absolutely packed with great flavors! The peanut butter swirl topping crisps up wonderfully, and perfects the trifecta of flavors in each and every bite!
Preheat oven to 350 degrees F (175 degrees C) and grease a 9x13 baking pan with butter, oil, or non-stick cooking spray.
(optional - if your peanut butter is refrigerated) In a small bowl add peanut butter and place in microwave. In short bursts of 15-30 seconds heat peanut butter just enough to make it soft and spreadable. Set aside.
In a large mixing bowl mash the over ripe bananas, then add the 1 ¼ cups sugar, ½ cup melted butter, 2 teaspoons vanilla extract, and pinch of salt. Stir to combine.
Next sift in the flour and cocoa powder. Fold in without over-mixing.
Once combined, pour the brownie mixture into your prepared 9x13 baking pan.
Add spoon fulls of the ½ cup room temperature or softened creamy peanut butter and then use a butter knife to swirl in the peanut butter.
Place baking tray into your 350 degrees F (175 degrees C) preheated oven for 25-30 minutes or until an inserted toothpick comes out without wet batter. *The longer you bake your brownies the more 'set' they will be. Slightly under-baked yields fudgier brownies.
Remove from oven and allow to cool completely before serving.
