- Diet-Friendly Options: Easily adaptable for gluten-free needs by using gluten-free oats and flour; these cookies can fit various dietary preferences.
Ingredients You’ll Need
- 1 ½ cups (186g) all-purpose flour: This forms the base of the cookies. For gluten-free alternatives, almond or oat flour can work great.
- 1 teaspoon ground cinnamon: This spice adds warmth and depth to the flavor. You can use nutmeg for a different twist if desired.
- ½ teaspoon salt: Balances the sweetness and enhances all the flavors, making the cookies even more delicious.
- 1 teaspoon baking soda: Helps the cookies rise, creating that perfect chewy texture.
- ½ cup unsalted butter, softened: Provides richness and moisture. If you need a dairy-free option, coconut oil works well.
- ½ cup (100g) granulated sugar: Sweetens the mixture and contributes to the cookie’s texture.
- 1 cup (200g) packed brown sugar: For that moist, caramel flavor that makes these cookies breathtakingly good.
- 2 medium overripe bananas, mashed (approximately 1 cup): The star ingredient; they add natural sweetness and moisture to the cookies.
- 1 large egg: Binds the ingredients together, giving the cookies structure.
- 1 teaspoon vanilla extract: A flavor enhancer that complements the bananas beautifully.
- 3 ¼ cups quick cooking oats: They give the cookies a hearty texture. Old-fashioned oats can be a substitute for a chewier texture.
- 1 ½ cups chocolate chips (optional): Add them for a delightful chocolate burst; feel free to use dark, milk, or even white chocolate.
How to Make Banana Oatmeal Cookies
- Preheat Your Oven: Set your oven to 350°F (175°C) and line two baking sheets with parchment paper or silicone mats.
- Mix the Dry Ingredients: In a medium bowl, whisk together 1 ½ cups of all-purpose flour, 1 teaspoon of ground cinnamon, ½ teaspoon of salt, and 1 teaspoon of baking soda. Set this bowl aside; it’s important to combine these first.
- Cream the Butter and Sugars: In the bowl of a stand mixer fitted with the paddle attachment (or a large bowl with an electric hand mixer), cream together ½ cup of softened unsalted butter, ½ cup of granulated sugar, and 1 cup of packed brown sugar on medium speed for about 3 minutes until light and fluffy.
- Add the Wet Ingredients: Incorporate the mashed bananas, 1 large egg, and 1 teaspoon of vanilla extract into the butter-sugar mixture and blend until combined; it’s okay if the banana mixture is a bit lumpy; that’ll only add to the texture!
- Combine Dry and Wet Mixtures: Gently add the flour mixture to the wet ingredients. Mix just until everything is combined, then fold in 3 ¼ cups of quick-cooking oats. If you’re adding chocolate chips, now’s the time—stir those in gently.
- Shape the Cookies: Using a scoop or tablespoon, drop 2-tablespoon-sized balls of dough onto the prepared cookie sheets, placing them about 2 inches apart.
- Bake: Pop the cookies in the oven and bake for 10-15 minutes or until they are light golden brown and no longer glossy on top. The edges should look set while the centers remain soft.
- Cool: Allow the cookies to rest on the baking sheets for 3-5 minutes to firm up before moving them to a wire rack to cool completely.
Storing & Reheating
Store your cooled Banana Oatmeal Cookies in an airtight container at room temperature for 3-5 days, where they’ll stay soft and delicious. For longer storage, pop them in the refrigerator; they can last up to a week. You can also freeze them for up to three months; just ensure they’re well-wrapped to avoid freezer burn. When craving a warm cookie, reheat them in the microwave for about 10-15 seconds. They may lose a bit of their texture, but a quick zap will restore some of their softness.
Chef’s Helpful Tips
- Make sure your butter is softened to room temperature; hard butter won’t cream well with the sugars.
- Room temperature eggs help create a smooth batter, making for a better texture.
- If your cookie dough seems too dry, you can add a splash of milk to bring it together.
- For chewier cookies, don’t flatten the dough balls too much before baking.
- Customize your cookies by adding nuts, dried fruits, or different types of chocolate chips based on your preferences.
- These cookies freeze wonderfully; consider making a double batch for future treats!
Banana Oatmeal Cookies are the epitome of comfort food, bringing warmth and joy with every bite. Their perfect blend of sweetness, chewiness, and a bit of chocolate indulgence makes them an absolute hit. This recipe’s versatility extends from casual snacking to celebratory gatherings, and the best part? They’re friendly on the budget and your schedule. Feel free to experiment with mix-ins like nuts or dried fruits to make them uniquely yours. Enjoy these cookies fresh or share them with loved ones, and get ready for smiles all around!

Recipe FAQs
Can I use old-fashioned oats instead of quick oats?
Absolutely! Using old-fashioned oats will give your cookies a chewier texture. Just note that they might require a slightly longer baking time to achieve the perfect consistency.
How do I ensure my cookies stay soft?
Keeping your cookies in an airtight container is key. Adding a slice of bread to the container can help keep them moist, or you can underbake them slightly for a softer center.
Can I make these cookies vegan?
Yes, you can make vegan Banana Oatmeal Cookies by substituting the egg with a flax egg (1 tablespoon ground flaxseed mixed with 2.5 tablespoons water, let it sit until it thickens) and using coconut oil instead of butter.
What can I do with leftover ripe bananas?
If you’ve got leftover ripe bananas, don’t hesitate to make a double batch of these cookies! Alternatively, you could mash them up and freeze them for smoothies or pancake batter later on.
