I have been making a lot of oatmeal recipes lately. I just can’t seem to stop. My latest are these 4 ingredient flourless peanut butter oatmeal cookies. These cookies are similar to my 2 ingredient banana oatmeal cookies. While I love making those cookies, a few people found them to be a little too plain. This version adds more flavor and they have a chewier texture.

  • Bananas
  • Peanut Butter
  • Rolled Oats
  • Add-In of Your Choice (chocolate chips, dried cranberries or other dried fruit)


You want very ripe or overripe bananas so that you can mash them down just like you would for banana bread.

Peanut Butter

Use creamy natural peanut butter with no added sugar. This peanut butter will be easier to stir and mix into the batter.


As you can see from the photos, I used chocolate chips. But if you want to make them even healthier, I would use dried fruit like dried cranberries, blueberries or cherries. You should try to use something sweet because the cookies are not very sweet on their own since there is no added sugar.

  • 1 cup mashed ripe bananas (approximately 3 small bananas)
  • 1/2 cup natural creamy peanut butter unsweetened
  • 2 cups rolled oats
  • 1/2 cup chocolate chips or dried fruit


  • Preheat oven to 350°F. Line 2 baking sheets with silicone baking mats or parchment paper.
  • In a large bowl add bananas and peanut butter. Stir until evenly mixed. Add in oats. Stir until evenly combined.
  • Add in chocolate chips or dried fruit. Stir until evenly combined.
  • Using a 1 ½ tbsp cookie scoop, scoop cookie batter and place onto prepared cookie sheets, spacing them about 2 inches apart. Use the palm of your hand to press down and flatten cookie. Cookies will not spread during baking so shape the cookie batter to your desired cookie shape.
  • Bake cookies about 10 minutes or until set. Let cookies cool completely before removing from baking sheets.


  • Slightly adapted from The Big Man's World
  • Make sure to thoroughly mash your bananas. You should not have any large chunks.
  • If you want to make your cookies prettier, you can save half of the chocolate chips and place them on top of the cookie after it is flattened.

  1. My husband loves oatmeal cookies and replacing the flour makes these my favorite.

  2. Can I use something other than bananas? I would love to try these with applesauce instead! Anyone? I do want to make them as is too.

  3. wow awesome I love to try these wit no sugar since I’m a ore diabetic thank you so much 10.stars

  4. Thank you for all the recipes. Have a beautiful day ??

  5. I cannot find the amount of ingredients to include in the recipe

    • Please see the recipe card at the end of the post before the comments section. All of the ingredient amounts and instructions are listed there.

  6. I have a nut allergy so tried using Biscoffi spread. the flavour was great but they fell to pieces. any suggestions please.

    • Biscoff spread has sugar and flour in it, which is why it did not work. I would try sunflower seed butter.

  7. I will try this recipe sounds really delicious and healthy is always a plus. Thank you

  8. Hi, is there an alternative to peanut butter as my family have a nut allergy?
    Thank you for the lovely recipes.

    • Can you have other nut butter? If so, you can sub almond butter or cashew butter. If not, another alternative is sunflower seed butter, but we have not tested it with the recipe.

  9. Great ? ? ? ? ? ?

  10. its a very nice recipe I’m just wondering if I could use some sweetener as well, I have a very sweet tooth
    so has my grandson, but I don’t want to use sugar.

  11. Thank you for your recipe have a good day this is additional nutritious alternative to abundant bananas in market which just get thrown in trash for cooking alternative

  12. I was glad to see you can use applesauce as a substitute for bananas…I feel it is soo important to have healthy snacks like this made constantly…and have them sitting close by so when grandkids come over, they can grab one as they head out to play, and guest can enjoy them as well…plus, it’s so Great ! they are healthy, quick, and so easy to make. No messy kitchen to clean, Yayyy! Tip: It wasn’t mentioned but, Gluten Free Oatmeal is a must in my recipes.. I use Bob’s Red Mill

  13. Just wondered if you could use frozen bananas?

  14. Thank you!

  15. How do you store these cookies? Sealed container? Refrigerate? re-warm to eat?
    Love the recipe….I added a little Nutella and candied ginger.

    • For storage, you should keep them in an airtight container in the refrigerator. We don’t recommend warming them up.

  16. Has anyone tried making these into bars rather than shaping them into cookies?

  17. These look delicious, but I am allergic to peanuts and tree nuts, is there a different substitute for the peanut butter?

    • Sunbutter is often used as a substitute but it will change the flavor of the cookies. We can’t say how it will work without trying it, so let us know if you do.

  18. I am so happy about these delicious healthy snacks, do you have any suggestions, what to do with all the white and brown sugar,, I have 10 pounds white sugar, and 3 pounds of brown?

  19. Can you indicate in he recipes, if it’s ok for diabetics?

  20. Would the powdered Peanut Butter that your mix with water work well with your recipes??

  21. Delicious! I appreciate that they are not very sweet. I did use quick cook oats because that’s all I had. Very easy to make. I will definitely make again. Thanks for the recipe. 

  22. These are sooooooo delicious! So easy to make and perfectly sweet. Instead of peanut butter I used homemade almond butter.  I liked the soft texture and really easy to reheat!
