These peanut butter and banana cookies are made pretty often in our house. They contain healthy fats from the peanut butter and a great source of oats, making them a great, filling snack. They are a great sweet treats that even the adults will love as well!

WHAT YOU’LL NEED

Here is what you’ll need to make these peanut butter and banana cookies:

Ingredients to make peanut butter and banana cookies. See recipe card for detailed ingredient quantities.
  • Rolled Oats: I love baking with rolled oats as they are packed with nutrition! Gluten-free rolled oats make these granola bars gluten-free.
  • Oat Flour: I usually make my own oat flour by blending up rolled ups into a flour. The ratio is 1:1!
  • Banana: The main source of sweetness for these granola bars. Try to use bananas that are very ripe with several brown spots. The riper the bananas, the sweeter the bars!
  • Peanut Butter: For added healthy fats and flavor.
  • Cinnamon: Provides an extra warm spice and subtle sweetness.

PROCESS

  1. Puree or mash the banana with a fork until smooth.
  2. Add in the peanut butter and mix until combined.
  3. Stir in the rolled oats, oat flour, and cinnamon and mix until combined. The mixture may seem wet but will firm up while baking. Let the mixture sit for a few minutes so that the oats can soak up some of the moisture.
  4. Scoop out tablespoon-sized portions onto a parchment paper-lined pan and use your hands to flatten and shape the cookies. Please note that the batter is wet and sticky (unlike a typical cookie batter), so it may help to wet your hands a little while shaping. If you are using toppings, press the toppings into the top of each cookie.
  5. Bake at 350 degrees F for 10 minutes, or until the cookies are set.

STORAGE INSTRUCTIONS

Once cooled, store the cookies in an airtight container at room temperature for up to 2 days, or in the refrigerator for up to 5 days. To freeze, store in a freezer-safe Ziploc bag with parchment paper-lined between each cookie to prevent sticking for up to 2 months.

SUBSTITUTIONS

  • Peanut Butter: The peanut butter may be replaced with a seed based butter like sunflower seed butter.
  • Oat Flour: You may replace the oat flour with equal parts rolled oats. You may also replace it with unsweetened desiccated coconut or almond flour. Check out this recipe for almond cookies or this recipe for coconut cookies!

RECIPE NOTES

  • Make sure to flatten and shape the cookies beforehand because they will not change shape while baking.
  • If you want your cookies to have a smoother texture with no lumps, puree the banana first and then stir in the oats.
  • I like to use very ripe bananas with several brown spots. The riper the bananas, the sweeter the cookies.
  • The mixture will seem sticky and wet at first, but it will harden up while baking.

    My LO isn’t a fan of muffin or cookies and he finally has these today. Thank you so much.

    I’ve flash freeze a couple of the cookies. How do you serve from frozen next time?

    1. I’m so happy to hear that your little one liked these cookies! From frozen, I usually reheat in the microwave for a few seconds (adding 10 second increments if needed) and then served once cooled😊

  2. These look amazing! Going to make it now with some overripe bananas my son didn’t get to! What did you drizzle on top?
