Healthy Peanut Butter Banana Oatmeal Cookies are a great way to use overripe bananas.

Key Ingredients 


Rolled oats and quick-cooking oats both work fine. As you will learn later in this post you will choose the texture of your cookies by grinding half or all the oats, or leaving them as they are.

If you use quick oats the texture of the cookies will be more delicate.

If you want super chewy cookies with delicate texture you can use oat flour.


Make sure to use very ripe bananas. Thone easy cookies are a perfect way to use overripe bananas. Somehow they always end up this way.

Ripe bananas, with brown spots on the skin, are sweeter and they mush easily.


Both smooth and crunchy peanut butter work great in this recipe. I like tiny crispy pieces of peanuts in the cookies when I use crunchy type.

Just make sure to use natural peanut butter, without unnecessary additions like palm oil.Creamy peanut butter is easier to mix with other ingredients, while the one containing vegetable fats is usually more solid.

You can swap it for natural almond butter, sunflower seed butter or even cashew butter.


It will provide sweetness and will thin the cookie dough a little, as other ingredients are quite thick.

How To Make Peanut Butter Banana Oatmeal Cookies?

GRIND OATS (optional)

I usually grind half of the oats to have a little smoother, fluffier cookies with crispy texture from whole oats.

You can grind the whole batch of oats for more delicate consistency or leave all of them whole for tougher cookies with more bite and crisp.


In a large bowl mash banana with a fork. It will be very easy with overripe bananas. 

Mix in peanut butter and maple syrup. If you want to do it quickly, and don’t want to have tiny pieces of mashed banana in the dough, you can blend the ingredients in a food processor.

If you decide to use any additions, you can mix them in now.

Add the oats and mix all ingredients to create thick dough.

Scoop flat tablespoon of the dough, place it on the baking sheet lined with parchment paper and flatten a little to form the cookies. 

They will not spread very much, so you need to give them the shape you want.

If you prefer more crunchy texture, spread the dough thinner.


Bake peanut butter oatmeal cookies in the oven preheated to 180 for 10-12 minutes until they turn golden brown. Keep them on a cookie sheet for a few minutes, before transferring them to a cooling rack.

Questions & Answers 

How To Store Banana Oat Peanut Butter Cookies?

You can keep them in the airtight cookie jar on the countertop for 2-3 days. If you made a bigger batch and want them to last longer I suggest storing them in an airtight container in the fridge.

What Else Can I Add to the Cookies?

  • Dark chocolate chips or chunks (to the batter or on top, or both as my husband would do)
  • Cranberries or raisins
  • 1 tbsp vanilla extract 

Are They Chewy Or Crispy?

Those are chewy cookies with a little crisp on top from baked oats.
