Why You’ll Love This Recipe

Simple & Quick: Ready in just about 30 minutes, including baking time!
Irresistible Flavor: The bananas provide natural sweetness and moisture, making each bite soft and delicious.
Eye-Catching Appeal: Beautifully golden brown and studded with chocolate chips, they look as tempting as they taste.
Flexible Serving: Perfect for breakfast, snacks, or dessert—enjoy anytime, anywhere.
Diet-Friendly Options: You can easily substitute ingredients to fit dietary needs, like using gluten-free oats.

Ingredients You’ll Need

1 ½ cups all-purpose flour: Regular all-purpose flour provides structure. For a gluten-free version, use a gluten-free flour blend.
1 teaspoon ground cinnamon: Adds a warm, fragrant touch, enhancing the overall flavor. Feel free to use more or less depending on your taste.
½ teaspoon salt: Balances the sweetness, making the flavors pop.
1 teaspoon baking soda: This is your leavening agent, helping the cookies rise to perfection.
½ cup unsalted butter (softened): Provides richness and helps create a chewy texture. If you prefer dairy-free, use a plant-based butter alternative.
½ cup granulated sugar: This helps to sweeten the cookies while keeping them tender. You can replace it with coconut sugar for a healthier option.
1 cup packed brown sugar: Adds moisture and a deep, caramel flavor to the cookies.
2 medium overripe bananas (mashed, approximately 1 cup): The star of the show! Overripe bananas are sweeter and easier to mash, making them perfect for baking.
1 large egg: Binds everything together. For an egg-free version, try using a flaxseed meal substitute.
1 teaspoon vanilla extract: Infuses a warm, sweet aroma throughout the cookies.
3 ¼ cups quick cooking oats: These oats provide a chewy texture that complements the softness of the bananas.
1 ½ cups chocolate chips (optional): Chocolate adds a delightful touch if you’re craving something extra sweet!

How to Make Banana Oatmeal Cookies

Preheat the oven and prepare baking sheets: Start by preheating your oven to 350°F. Line two cookie sheets with parchment paper or silicone mats for easy cleanup.
Mix dry ingredients: In a medium bowl, whisk together 1 ½ cups all-purpose flour, 1 teaspoon ground cinnamon, ½ teaspoon salt, and 1 teaspoon baking soda. Set this mixture aside as it will help the cookies rise beautifully.
Cream butter and sugars: Using a stand mixer fitted with the paddle attachment or a hand mixer, cream together ½ cup softened unsalted butter, ½ cup granulated sugar, and 1 cup packed brown sugar on medium speed until the mixture is light and fluffy, about 3 minutes.
Incorporate bananas and egg: Add in your mashed bananas (about 1 cup from 2 overripe bananas), 1 large egg, and 1 teaspoon vanilla extract. Mix until just combined. The mixture may look slightly lumpy, which is perfectly fine.
Combine dry and wet ingredients: Gradually add the flour mixture into the banana mixture, mixing until just incorporated. Be careful not to overmix; you want to keep the texture light.
Fold in oats (and chocolate chips if using): Now, stir in the 3 ¼ cups quick cooking oats until evenly distributed in the dough. If you’re using chocolate chips, add them in at this stage for that extra bit of sweetness.
Shape and bake the cookies: Use a 2-tablespoon cookie scoop to form dough balls and place them about 2 inches apart on the prepared cookie sheets. Bake for 10-15 minutes or until the edges are lightly golden and the tops are no longer glossy.
Cool and enjoy: Allow the cookies to cool on the baking sheets for about 3-5 minutes before transferring them to a wire rack to cool completely. Trust me, the waiting will be worth it when you take that first bite!

Storing & Reheating

To keep your banana oatmeal cookies fresh, store them at room temperature in an airtight container for up to a week. For longer storage, pop them into the refrigerator, where they’ll last for about two weeks. If you want to keep some for a few months, freeze them! Just wrap each cookie individually in plastic wrap and place them in a freezer-safe bag. When you’re ready to enjoy them again, simply reheat in a preheated oven at 350°F for about 5-7 minutes, or until warmed through. They might lose a bit of their initial softness in the freezer, but a little time in the oven will revive that gooey goodness!

Chef’s Helpful Tips

Banana ripeness matters: Make sure your bananas are overripe for the best natural sweetness and moisture.
Don’t overmix: Gently fold the ingredients together to keep your cookies soft and chewy.
Customize flavors: Experiment by adding nuts, dried fruits, or spices like nutmeg to give your cookies a unique twist.
Chill the dough: If you have time, chilling the dough for 30 minutes before baking can enhance flavor and texture.
Don’t skip the cooling: Allowing cookies to cool properly ensures they hold their shape and retain moisture.

Banana oatmeal cookies are a joy to bake and eat—packed with wholesome ingredients and just the right amount of sweetness. Perfect for family gatherings, quiet evenings, or a little something to brighten your day. Don’t hesitate to try variations, swap in different mix-ins, or even adjust the spices to suit your preferences. The kitchen is your playground, and these cookies invite you to enjoy that creativity.

Recipe FAQs

Can I make these cookies without eggs?

Absolutely! For an egg substitute, mix 1 tablespoon of flaxseed meal with 2.5 tablespoons of water. Let it sit for a few minutes until it becomes gelatinous, and then add it to your batter in place of the egg.

How do I know when my cookies are done?

Look for a light golden color around the edges, and make sure the tops are set and no longer glossy. A toothpick inserted in the center should come out clean or with a few moist crumbs.

Can I use old-fashioned oats instead of quick cooking oats?

Yes, you can! However, keep in mind that old-fashioned oats create a heartier texture, and the baking time may vary slightly, so watch closely.

What’s the best way to store leftover cookies?

Place them in an airtight container at room temperature for about a week. If you want to keep them longer, freezing them is an excellent option. Just make sure to wrap them well to avoid freezer burn!
