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.
