Ingredients you’ll need:

  • Bananas: Add natural sweetness, moisture, and help bind the bars together.
  • Peanut butter: Provides richness, structure, and protein while keeping the bars soft and satisfying.
  • Maple syrup: Sweetens the bars naturally and adds a subtle caramel-like flavor.
  • Vanilla extract: Enhances all the flavors and adds warmth to the overall taste.
  • Rolled oats: Give the bars structure, chewiness, and make them filling.
  • Cinnamon: Adds warmth and depth that pairs perfectly with banana and peanut butter.
  • Baking powder: Helps lighten the texture so the bars aren’t dense or heavy.
  • Chocolate chips or nuts – Optional toppings for added flavor and texture.

How to make peanut butter banana oatmeal bars:

(The full written and printable recipe is further below.)

Step #1) Mash the bananas with a fork in a large mixing bowl.

Step #2) Add the peanut butter, maple syrup, and vanilla. Mix together until combined.

Step #3) Add the rolled oats, cinnamon, and baking powder. Mix with a rubber spatula until combined.

Step #4) Transfer the mixture to a parchment paper-lined 8×8″ pan. Top with chocolate chips or nuts if desired. Bake at 350F for 20-25 minutes.

🌟 Expert tips:

  • Use overripe bananas: The riper the bananas, the sweeter and more flavorful the bars will be without needing extra sweetener.
  • Stick with rolled oats: Quick oats can make the bars mushy, while rolled oats create the best chewy texture and structure.
  • Let them cool completely: Cooling allows the bars to firm up and be sliced cleanly without falling apart.
