Hot Tips for The Best Banana Oatmeal Cookies

Make the day you want to eat them, or freeze right after cooling: these banana oatmeal cookies are best on day 1, or keep very well in the freezer.
Don’t increase the amount of add-ins. I included just the right amount so the cookies don’t fall apart before or after baking.
Use truly ripe bananas. For sweet, big banana flavor, use the ripened, spotty bananas.
Serve with peanut butter… for a satisfying snack. The combo is delicious.
Don’t make the dough in advance. Once the bananas as mashed, they’ll brown very quickly. It’s best to bake this cookie dough immediately.

How to Make 3 Ingredient Oat Banana Cookies

These 3 ingredient oat banana cookies come together in no time at all. The result is soft and moist cookies made with simple, guilt-free ingredients.

First, preheat the oven to 350°F. Then grab a nonstick cookie sheet, or line a baking sheet with parchment paper.

Second, mash the banana in a medium mixing bowl.

Third, add in oats and add-ins. Stir and fold until thickened into a banana oatmeal cookie dough.

Using a cookie scoop, scoop and drop balls of dough onto the prepared cookie sheet. Flatten with a fork.

Bake for about 12 minutes. Cool, and enjoy the best 3 ingredient banana oatmeal cookies!

Storing & Freezing

Funnily enough, storing these 3 ingredient banana oatmeal cookies at room temperature is actually worse than storing them in the freezer.

To Refrigerate: Once cooled, store banana oatmeal cookies in the refrigerator for 1-3 days, maximum. Ripe banana baked goods are best on the first day.

To Freeze (recommended): If you’re not enjoying these delicious 3 ingredient banana oatmeal cookies on the first day, I recommend freezing them. Keep for 1-3 months in the freezer, just like these healthy peanut butter oatmeal cookies.
