How To Make 3 Ingredient Banana Oatmeal Cookies

Here you’ll find a look at the process of making Banana Oatmeal Cookies. You can find the full printable recipe at the bottom of the post.

  • Mix: In a medium bowl, mash bananas to a fairly smooth consistency (a few small chunks are okay). Add oats and mix well (shown above). Add chocolate chips and mix again. If the mixture is really wet, add a few tablespoons of oats (shown below).

  • Scoop: Using a 1 tablespoon measuring spoon or trigger scooper, scoop up the mixture and place it on a cookie sheet 1 to 2 inches apart. I left mine in a dome shape; you could flatten it out a bit with your fingers to make a flatter shape. Depending on the size you scoop out, you should get anywhere from 12 to 16.

  • Bake: Place in the oven on the center rack and bake for 15 – 20 minutes. If you made the scoops on the larger side, bake for 20 – 25 minutes. Remove from oven, and let cool a few minutes before eating.

And now you are ready to enjoy!

Soft, moist, and chewy, just like a bite of banana bread!

These are perfect for breakfast, snacking, or any time you are craving a healthy cookie with simple ingredients!

Baking Tips

  • Add-ins: Change it up with optional add-ins such as cinnamon, chopped nuts, shredded coconut, etc. Alternatively, don’t use any add-ins for a 2 ingredient cookie.

  • 1/4 cup shredded coconut
  • 1/4 cup chopped nuts

  • 2 tablespoons nut butter (homemade Almond Butter)

Instructions

Preheat oven to 350 degrees F. Line a baking sheet with parchment paper, silicone mat, or lightly grease with oil.

Store: Leftovers can be kept loosely covered and eat within a 1 – 2 days (if they last that long!).

Notes

Looking to make this refined sugar free, use cacao nibs in place of chocolate chips.

The riper the banana, the sweeter your end result will be. I’ve used rolled oats (like you see here) and quick oats, both with great success. Also, I’ve had batches come out looking lighter than what you see here, usually when using quick oats, so your coloring may vary. They may also darken a bit overnight due to the banana.

I’ve made this recipe many times since sharing. I find that each time my mixture might be a little different. It’s never been too dry but sometimes seems too wet. This may be that my bananas were large, or extra ripe and soft. If you happen to think the mixture is too wet, add more oats.

You can play around with adding more bananas and oats making a larger batch as well. Since these don’t spread on the baking sheet. I’ve made 24 on an average baking sheet.

Try using this DIY Muesli Mix in place of plain oats. It delicious and makes it more of a trail cookie!

  1. I made it twice till now, and I think will moreover again, it’s very easy to someone doesn’t like to many steps or ingredients like me. I tried to microwave it only for 5-8 seconds if I am eating it the next day, it’s awesome, I also share it with my friends and they loved it and were thinking to add protein powder in it but I don’t know what the results will be.
    Thank you so much for this recipe.






  2. I love everything about these cookies! Just tried them for the first time last night. Thank you for this recipe. I can’t wait to try some of the other add ins.






  3. Made these today! Really nice! I omitted choc chips. Added walnuts and dates and flavoured them with cardamom and vanilla. Baked them in a toaster oven for 15 min (flattened). Perfect! Thank you!
