Why this recipe works

When you have ripe bananas, sure you could make banana bread, but you can also whip up a quick batch of cookies with just 3 ingredients! These cookies are completely egg-free and flourless but taste just like mini chocolate chip banana bread bites!

This easy 3-ingredient cookie recipe is also healthy, using bananas and oats as the base. In fact, you could make this a 2-ingredient banana oatmeal cookie. The chocolate chips are a nice addition but definitely not necessary!

These cookies still satisfy the cravings without the excessive calories and fat typically found in sweets. And they also can make a great on-the-go breakfast option! Yes, that’s right—cookies for breakfast! That’s because these could also pass for baked oatmeal bites. I’m giving them lots of names but call them what you like!

Ingredient notes

Just three simple, easy to find ingredients—short and sweet! Reference the recipe card at the bottom for exact measurements.

Ingredients for 3 ingredient cookies labeled.

Bananas—ripe is best. The more brown spots, the better, as they’ll make for a sweeter cookie.

Oats—rolled oats or quick oats are recommended. Anything else will be too hardy for the banana to soak into and will leave you with dry cookies.

Chocolate chips—I like these dairy-free ones but any will do. You can also use cacao nibs for a sugar-free option.

Optional add-ins:

-vanilla extract
-ground cinnamon
-dried fruit
-chopped nuts
-shredded coconut
-peanut butter

4. Use a tablespoon to scoop mixture out and place on a cookie sheet lined with parchment paper. Press down slightly to shape cookies. Bake for 12-15 minutes at 350F until golden and chocolate chips have started to melt. Remove from the oven and allow to cool for a few minutes before eating.

Enjoy!

How to store

If you’ve somehow managed to not eat all of the cookies in one sitting, you can store them in an airtight container on the countertop for a couple days or in the refrigerator for up to 5 days.

To freeze cookies, allow to cool to room temperature, then place in a freezer-safe container. Cookies can be frozen for up to 3 months. Thaw overnight in refrigerator before consuming or heat in a microwave for 20-30 seconds.

Expert Tips

  • Quick oats and rolled oats are best. Quick oats absorb more liquid but rolled oats work great as well for a heartier cookie. You can also you a combination of both together.
  • These cookies do not spread when baking so form them into a cookie shape if desired. You can also just scoop the batter and “drop” it on the baking tray. They don’t have to be pretty!
  • The ripened banana adds the sweetness but if you don’t have bananas you can use applesauce as well. About 1/4-1/2 cup for one banana. If you do have a banana but it isn’t ripened yet, you can blend it up in a food processor or blender first to make it easier to mash, then add a splash of maple or agave syrup for some sweetness. You may need to add more oats to balance it out.
  • Got a whole bunch of ripened bananas? Double or triple the recipe! It’s easy to eat a lot of these since they’re so delicious—I highly recommend making a large batch if you have more bananas!
