Ingredients You’ll Need
- 1 ½ cups all-purpose flour: This is the base of our cookies, giving structure. You can substitute with an all-purpose gluten-free blend if needed.
- 1 teaspoon ground cinnamon: It adds warmth and depth of flavor that complements the bananas beautifully.
- ½ teaspoon salt: Balances sweetness and enhances the flavors overall.
- 1 teaspoon baking soda: Helps the cookies rise and achieve that perfect chewy texture.
- ½ cup unsalted butter, softened: Rich in flavor and keeps the cookies moist. If you’re looking for dairy-free options, coconut oil works well as a substitute.
- ½ cup granulated sugar: Sweetens the cookies while helping them to crisp slightly. You can reduce the amount if you’re using very ripe bananas.
- 1 cup packed brown sugar: Adds moisture and a hint of caramel flavor, making the cookies chewy.
- 2 medium overripe bananas, mashed (approximately 1 cup): The star of the recipe! The more overripe, the sweeter the cookies. Frozen bananas work too—just thaw and mash!
- 1 large egg: Binds the dough together and adds richness.
- 1 teaspoon vanilla extract: Enhances all the other flavors and adds a hint of sweetness.
- 3 ¼ cups quick cooking oats: The core of our cookies, creating a hearty texture. If you’re looking for extra chewiness, old-fashioned oats can also work.
- 1 ½ cups chocolate chips (optional): Adds a melty, sweet element that makes these cookies even more delicious!
How to Make Banana Oatmeal Cookies
Preheat the oven: Start by preheating your oven to 350°F (175°C). This ensures that the cookies bake evenly. Line your baking 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. This step helps to evenly distribute the leavening agent and spices.
Cream butter and sugars: In the bowl of a stand mixer fitted with the paddle attachment (or a large bowl with an electric mixer), cream together ½ cup softened unsalted butter, ½ cup granulated sugar, and 1 cup brown sugar on medium speed until fluffy—about 3 minutes.
Combine wet ingredients: Once creamy, add the mashed bananas, 1 large egg, and 1 teaspoon vanilla extract. Mix until everything is well blended, though the mixture may be slightly lumpy.
Incorporate dry ingredients: Gradually add the flour mixture to the wet ingredients, mixing just until combined. Do not overmix, as this can lead to tough cookies.
Stir in oats and chocolate: Fold in 3 ¼ cups quick-cooking oats and, if desired, 1 ½ cups chocolate chips using a spatula or wooden spoon. The dough should be thick and slightly sticky.
Scoop onto baking sheets: Using a cookie scoop or spoon, drop 2-tablespoon-sized balls of dough onto the prepared baking sheets, leaving about 2 inches of space between each cookie.
Bake the cookies: Place the sheets in the preheated oven and bake for about 10-15 minutes, or until they are lightly golden around the edges and set in the center. The tops should no longer look glossy.
Cool: Allow the cookies to cool on the baking sheets for 3-5 minutes before transferring them to a wire rack to cool completely. This short cooling time helps them firm up, making them easier to handle.
Storing & Reheating
Store your banana oatmeal cookies in an airtight container at room temperature for up to 3 days or in the refrigerator for up to a week. For longer storage, freeze the cookies in a sealed plastic bag for up to 3 months. To reheat, simply pop them in the microwave for 10-15 seconds or warm them in the oven at 350°F for about 5 minutes. Keep in mind that a quick reheat might slightly change the texture, but they will still taste amazing!
Chef’s Helpful Tips
- Be sure your butter is soft but not melted. Softening at room temperature for 30 minutes should do the trick.
- Use very ripe bananas for maximum sweetness. Look for ones with plenty of brown spots; they are perfect!
- If your dough feels too sticky, add a touch more flour, a tablespoon at a time, until just right.
- To prevent cookies from spreading too much, chill the dough for 30 minutes before baking.
- If you’re a fan of nuts, consider adding chopped walnuts or pecans for an extra crunch.
It’s hard to resist the allure of fresh, warm cookies straight from the oven. The smell of banana oatmeal cookies baking is like a cozy hug on a chilly day, and sharing them is and even better treat.

Recipe FAQs
Can I make these cookies vegan?
Absolutely! You can replace the egg with a flax egg (1 tablespoon of ground flaxseed mixed with 2.5 tablespoons of water). Use olive oil or coconut oil as alternatives for the butter.
What kind of oats should I use?
Quick cooking oats work perfectly in this recipe as they absorb moisture faster and create a softer cookie. However, you can also use old-fashioned oats if you prefer a chewier texture!
How can I make these cookies gluten-free?
To make gluten-free banana oatmeal cookies, substitute the all-purpose flour with a gluten-free flour blend that can be used in baking. Make sure that your oats are certified gluten-free as well!
How do I know when the cookies are done?
Watch for a light golden edge and set centers. The tops should also be firm to the touch and no longer glossy. If you underbake slightly, they’ll maintain a chewier texture, which is delightful!
Now it’s time for you to experience the incredible satisfaction of baking Banana Oatmeal Cookies. From their mouthwatering aroma to their deliciously chewy texture, they’re sure to warm your heart and make your home feel cozy. Happy baking!
