Let’s not mistake these healthy banana oat cookies for traditional cookies, these are best eaten right out of the oven! They are soft and chewy, and so delicious!! Think banana nut bread only as a cookie. You can even eat them for breakfast or enjoy them as a snack or dessert. I’ve also created variations of these banana oatmeal cookies, try these Chocolate Chip Healthy Oat Cookie, and my PB & J Healthy Oat Cookie.

Banana Oatmeal Cookies

These banana oatmeal cookies are best right out of the oven, they are chewy and soft – just how I like my cookies! You can also make them as a two ingredient cookie, but walnuts and bananas are my favorite combination. Walnuts are nutrient-rich, they provide good fat, protein, fiber, and manganese, plus magnesium, iron, calcium, and B vitamins.


I’m always anxiously awaiting my bananas to get super ripe so I can make these cookies, which I have been making for years. I’ve made them with Chocolate Chips, and PB & J. You can try them with almonds, raisins, cinnamon, pumpkin spice, craisins and more!

They are also great for egg free, dairy free, gluten free (use gf oats), vegetarian, and vegan diets.


  • Your bananas should be super ripe.The riper the sweeter since we are not adding sugar here.
  • Leftover cookies can be frozen; let them cool then wrap tight in plastic wrap and freeze. Thaw or heat in microwave a few seconds before eating.
  • Rolled oats can be used in place of quick outs.
  • Check labels for gluten-free.

  1. Didn’t have any walnuts on hand, but I had a bottle of almond extract. Smells and tastes very good. I know it probably makes it a little less healthy, but I threw a tablespoon of butter in the mix.
    Makes awesome cookies! 

  2. Has anyone ever soaked the quick oats in almond milk before using them in these cookies? Love the flavor but the oats needed a little something to soften them up. 

  3. Can you use regular oatmeal rather than quick oats

  4. i added spices (nutmeg and cinnamon) and a dadh id vanilla.
    i agree with the other review it makes like 10 cookies. i got 9. i assume it could varry on banana size. i used a mini muffin pan to bake them. to me theirs not much to rate in regards to taste. its oats and bananas. it depends how well you mash, mix, and if you over/under bake them. i do love how its a simple base easy to change it up. i didnt add nuts by choice.

  5. Just made these and I can’t stop eating them!
    They are delicious, I added mini chocolate chips to half of the batter just to try it and oh my gosh so good! 
    Thank you for this recipe 🙂

  6. I love this recipe for a quick mid- day snack or a healthier treat with my morning coffee. I do add a small drizzle of honey, vanilla extract, a pinch of salt and whatever chocolate I have laying around. Not as heathy as the original
    Version but much better than a typical cookie! Oddly, I really like them chilled from the refrigerator.
