These 3-ingredient Banana Oatmeal Cookies may be the healthiest and easiest cookie recipe you’ll ever make! And they’re naturally gluten-free!

When you hear the words “Banana Oatmeal Cookies” and “just 3 ingredients,” your first reaction might be: “Yes, please”! And you’d be right! These snacks are moist, chewy, and so easy to make with just 3 ingredients …

Banana Oatmeal Cookies

There’s no added sugar, but (shh!) the kiddos don’t need to know that. The base of these Banana Cookies is made with ripe bananas, quick oats, and chunky peanut butter.

You could also add in vanilla extract, dried cranberries, chopped walnuts, and more for added texture and flavor.

How To Make Banana Oatmeal Cookies

1. Preheat oven to 350 degrees F and line a large baking sheet with parchment paper and set aside.
2. In a large bowl, mash the overripe bananas with a fork until only small lumps remain. Add the peanut butter, oatmeal, and chocolate chips to the mashed banana and mix until evenly combined.
3. Use a medium cookie scoop to measure heaping scoops of the cookie dough onto the prepared baking sheet. Use your fingers or palm to gently flatten the cookies.
4. Bake for about 15 minutes, remove from oven and allow to cool on the baking sheet for a few minutes before transferring to a wire rack to cool completely.

I just made these with my 3 year old. They turned out fantastic! We used old fashioned oats added chocolate chips as well as coconut flakes. And at my son’s instance, a squirt of honey. We baked for 20 minutes. I’m enjoying my third one as we speak!

Banana Oatmeal Cookie Mix In Variations

Another thing I love: you can add your own mix-ins to this simple cookie recipe.

My favorite is chocolate chips, and you can even use the dairy-free kind if you want. You can also try adding nuts, dried fruit, or shredded coconut. Basically, whatever is in your pantry works!

How To Freeze Banana Oatmeal Cookies

Make according to recipe directions and allow the cookies to cool completely before adding to an airtight container and freezing for up to 3 months. Thaw at room temperature.
