Peanut Butter Banana Bars are chewy, fudgy, and packed with goodness! Made with ripe bananas, peanut butter, and honey—no butter, oil, or white flour. One bowl, no fuss!
Preheat oven to 300°F. Line an 8x8 baking pan with parchment paper with an overhang for easy removal. These bars are near impossible to remove from an unlined pan. I wouldn’t recommend using foil.
Remove the banana peel and mash well using a fork. Measure after it has been well mashed.
In a large bowl, using a hand mixer, cream together the mashed up banana, peanut butter (don’t warm it up), honey, vanilla extract, and brown sugar. Beat until completely combined. Beat in the egg until incorporated.
Beat in the salt, baking soda, baking powder, and oat flour (see note 2). Add the peanut butter chips and fold in with a spatula.
Using a spatula, transfer the mixture into the prepared pan and smooth the mixture into an even layer. Bake 18–25 minutes or until lightly golden brown and bars have slightly pulled away from the edges. Be careful to not overbake or they end up dry and less flavorful.
Remove and allow them to cool before using the parchment overhang to pull the bars from the pan. Cut into bars and enjoy! Bars are best enjoyed within 1–2 days. (They have a tendency to get moist as they’re stored.)
Notes
Note 1: If your banana is not overly ripe (or sweet), you may want to slightly increase the amount of brown sugar.Note 2: To make oat flour, pulse oats in a blender or food processor until they are a flour-like consistency. Measure the oat flour after blending for the right amount.Storage: Store leftover bars in an airtight container at room temperature for 2–3 days or in the fridge for up to a week.
