How to make Banana Peanut Butter Oatmeal Cookies
Making these peanut butter banana cookies is so easy! Here's how it's done:
- Mash the bananas in a mixing bowl.
- Add the nut butter and dry ingredients then stir well.
- Use a cookie scoop or ice cream scoop to portion out on a prepared baking sheet.
- Flatten with damp fingers, press in a few extra chocolate chips for decoration, then bake in your oven. You can even make air fryer oatmeal cookies. Instructions are included in the recipe.
Tip - Make your cookies any size you like, just be sure to adjust the baking time accordingly. They should be baked until golden on the bottom and lightly browned and set on the top and sides.
Uncooked cookie dough can be left covered in the bowl for a couple of days in the fridge if you don't want to cook all of the cookies right away.
Store cooked and cooled Peanut Butter Banana Oatmeal Cookies in an airtight container in the fridge for up to 2 weeks. They can also be frozen for up to 3 months. Be sure to separate them with parchment paper before freezing so they don't stick together. They don't take long at all to thaw.

Peanut Butter Banana Oatmeal CookiesAuthor:
- 2 medium very ripe bananas , (about 276 grams / 10 oz once peeled)
- 6 tablespoons peanut butter , or any other nut/seed butter
- 1½ cup (150 grams) rolled/old fashioned oats
- ⅛ teaspoon fine sea salt
- heaping ¼ cup (50 grams) chocolate chips , plus a few more to decorate the top
To oven bake
- Preheat oven to 350F (175°C). Line a large baking tray with parchment paper.
- In a large bowl, mash the bananas with a fork until a wet, smooth puree.
- Add the peanut butter and mix together, working out any peanut butter lumps.
- Add the oats, salt and chocolate chips and stir well to combine.
- Use a cookie/ice cream scoop to drop portions of the cookie dough out on to the lined baking tray. My scoop holds 3 tablespoons. If yours is slightly different adjust the cooking time a little to compensate.
- Lightly wet your fingers and press each cookie mound down into an approximately half inch thick round and smooth around the edges to neaten them up.
- Press a few chocolate chips into the top and bake for 11 to 12 minutes, or until golden on the bottom and lightly browned and set on the top and sides. These aren't a crispy cookie, so will have some give if you press into the tops.
- Transfer to a wire rack to cool.
To air fry
- Make the cookie dough as above.
- Line air fryer basket with a piece of parchment paper, making sure to leave some space for air flow around the edges. Alternatively, if just cooking one or 2 at a time you can cut small cookie sized squares of paper. Leftover uncooked cookie dough will keep in the fridge for a few days.
- Scoop the cookie dough out onto the parchment paper, then with wet fingers, press each cookie mound down into an approximately half inch thick round and smooth around the edges to neaten them up.
- Air fry, on the bake setting if you have one, at 325 for about 8 minutes or until golden on the bottom and lightly browned and set on the top and sides. All air fryers vary so keep a close eye on them in the last few minutes.

I really love this recipe. I accidentally used 1 ½ cups oatmeal instead of ½ cup and they turned out like yummy biscuit cookies. Actually really yummy. I’ll have to make them correctly next time! I tried both the oven and air fryer method and I like the extra crispiness the air fryer gave it. Thanks Mel for another great recipe!

So pleased you enjoyed them Robyn! 1½ cups of oats is the correct amount so sounds like they turned out exactly as they should. Happy holidays!
Thanks for the inspo. I used 2 packs of cocoa and sea salt it make for the oatmeal. I honestly didn’t measure anything else. However I needed the tips and ingredients. Trying things for Veganuary.

This is my new go-to recipe for overripe bananas! Quick, easy and delicious. The recipe is perfect as written, although I did add a little cinnamon to my second batch for a slight variation. Will try some dried fruit next time. Thanks so much for all your delious recipes!
Air fryer approved! Made a double batch of these and we all really enjoyed them! I’m super happy because they were so quick and easy. Another use for my over ripened bananas! Thank you!!
Tastes great and healthy. I ground up my oats in the blender. Thank you for sharing this recipe!
I just made these tonight, Mel. They are SOOO good! For the 1/3 cup of oats, I used oat flour because the batter was too loose. I probably pureed the banana too much. My cookie scoop is 1 1/2 tablespoons so I baked them for 8 minutes and they are perfect. Thank you so much for another great recipe! 🙂 🍪

I'm so pleased you enjoyed the recipe! For future reference, the batter is a very loose and wet batter.
