How to Make 4 Ingredient Peanut Butter Banana Bars

Let’s create this cozy treat together! Follow these simple steps:

Preheat your oven to 350°F (175°C). Grease a loaf pan or line it with parchment paper for easy removal.
In a large bowl, add the ripe bananas and mash them with a fork until almost smooth—feel free to leave a few chunks for extra texture.
Stir in the smooth peanut butter and vanilla extract until fully combined, embracing that creamy goodness.
Add the quick-cooking oats, salt, and baking powder to the banana mixture. Mix well until everything is evenly combined.
Gently fold in 1/3 cup of the chocolate chips, saving the rest for the top of your bars.
Pour the mixture into the prepared loaf pan, smoothing it out on top with a spoon or spatula. Sprinkle the remaining chocolate chips evenly over the top.
Bake for 25-30 minutes, or until a knife inserted in the center comes out clean. You’ll know they’re ready when the edges are golden and fragrant!
Let the bars cool in the pan for a few minutes before transferring them to a wire rack. Once completely cooled, cut them into 6-8 generous pieces.

Fun Ways to Customize It

While these 4 Ingredient Peanut Butter Banana Bars are scrumptious as they are, here are a few fun variations you can try to add a personal touch:

Spice it Up: A sprinkle of cinnamon or nutmeg can elevate the flavors, making them even cozier.
