3 Ingredient Banana Bread Cookies

The infamous 3 ingredient banana cookies aren’t anything new- In fact, they were one of the first cookies I ever made growing up, thanks to the cereal box in most Australian households. I took the basis of that to share with you guys the three-ingredient pumpkin cookies and the three-ingredient applesauce cookies and today- The banana version.

While traditional 3 ingredient banana cookies call for flour, I wanted them to have a more ‘bread’ like texture. For that, I used gluten-free rolled oats.

There are some recipes out there which call for just two ingredients- The mashed banana and the oats but to be honest, unless I had three overripe bananas per half cup of oats, I was presented with nothing more than hockey pucks.

To compensate, I added some smooth peanut butter, but have definitely made this with my beloved almond butter before too.

The BEST healthy banana bread cookies

These healthy three ingredient flourless banana bread cookies are your quick sweet fix with kitchen items you’d most likely have on hand.

These cookies are soft, chewy, and if you use the gluten-free old fashioned oats, and have a texture similar to thick banana bread.

Naturally gluten-free and vegan, these cookies are also free from flour, butter, oil, or added sugars- Hi 5 to bananas for sweetness!

  • Bananas. The more overripe your bananas are, the sweeter your cookies will be. 
  • Rolled Oats (old fashioned oats). Provide the chewy texture, and goes so well with banana and peanut butter. You can use quick oats (instant oats) but they will be softer. 
  • Peanut Butter. Smooth, creamy, and drippy peanut butter must be used. If you use crunchy or thick peanut butter, you’ll find the cookies to be hard to mix.
  • Chocolate Chips. Optional, but highly recommended. 

In terms of substitutions, you can substitute the peanut butter for any smooth nut or seed butter. I enjoy them using almond butter and tahini.

The only suitable substitution for the oats is quinoa flakes. Be wary that if you use them, the cookies will be more soft and doughy. 


Making these banana bread cookies is super simple and requires just one bowl.

Start by mixing together your mashed bananas, oats, and peanut butter. Once mixed, fold through your chocolate chips, if using them. 

Form 12 balls of dough and place it on a lined pan. Bake for 10-12 minutes, at 180C/350F for around 10-12 minutes. Once the cookies go golden around the edges, remove and let cool on the pan completely. 

Remember, the cookies continue to cook as they cool. 


As these cookies have no flour, no butter, and no oil in them, they should not be stored at room temperature. 

Store the cookies in a sealable container in the refrigerator, or on a plate, covered in plastic wrap. Flourless banana bread cookies will keep for 5 days.

Can you freeze banana bread cookies? Yes, cookies are freezer-friendly and can be stored in the freezer. Wrap the cookies in parchment paper and place them in a ziplock bag or freezer-friendly container. Cookies will keep well frozen for up to 2 months. 


Lightly wet your hands and form the balls of cookie dough, instead of a cookie scoop. You’ll find the cookies form much better, and spread much less.

Do not over-bake the cookies. They will not become hard, but gummy if you over-cook them. Remove them when they just begin to go golden brown around the edges (10-12 minutes). They continue to cook as they cool down. 

If you want to make these cookies without oats, you can make these paleo breakfast cookies. They use almond flour, and are soft-baked! 

If you want to substitute the banana for something else, you can use unsweetened applesauce. Start with 1 ¼ cups, but you may need more oats (if the batter is too thin) or more applesauce (if the batter is too thick). 

These cookies are not super sweet- They rely on the banana for sweetness. If you prefer super sweet cookies, add some maple syrup or sweetener, to taste.

  1. I have never made an avocado dessert before. Avocados seldom make it beyond guacamole here…we’re talking several times a week…we are ADDICTED! Your cookies sound fabulous as usual and easy which is good. I am sharing my spicy carrot refrigerator pickles in your linkup because apparently a pickle tray is a thing in some areas at Thanksgiving…and its going to be in my house too, starting with this Thanksgiving. I grew up in the wrong part of the country…I LOVE pickles! I am so excited about the idea of a pickle tray! Woo hoo! I may not have room for turkey…

  2. I hope this doesn’t come out too creepy, but I must say – I can’t get enough of your cookies 😉

  3. These cookies look amazing!! Plus, with salted caramel chips?? Umm YUM! I am definitely going to try these once my bananas ripen, which hopefully will be soon because these just look too good.

  4. umm these look delicious Arman! Let me say, I know the struggle with that avocado pudding and getting it to look pretty :p but I’ve NEVER tried those chips..I MUST.

  5. OMG! I am definitely making these cookies this weekend. Salted caramel chips!?!? Yum!!

  6. First off, delicious and easy. Second off, a breakfast sandwich without eggs or cheese is unworthy of the name, or your taste buds.

  7. i love this banana bread version of your famous no-bake cookies, banana bread always holds a special place in my heart 🙂 i’ve tried avocado mousse and it was pretty good but i had to use so much chocolate and maple syrup to mask the flavor of the avocado which probably reversed it’s health benefits lol. chocolate chips and pecans are my #1 fav add-in, although i need to get my hands on those salted caramel chips too!

  8. I could visit your site on a full stomach and instantly become hungry again! These look awesome and easy to make. In other words, I’m making them….now. And yes to sweet avocado treats! Cacao + stevia + avocado in blender and I’m set.

  9. sometimes i think you read my mind. Like how i want banana bread but don’t want to make actual bread. so ya, these cookies —> SPOT ON and perfect for snacking

  10. I don’t like cookies. I like kale chips…. 😆 😆 😆

    Sorry, I couldn’t resist 😛 Pass me the chocolate chip cookies, pls & thx.
