Step-by-Step Instructions
Follow these simple steps to bake the most amazing Banana Oatmeal Cookies. This process is straightforward and guarantees delicious results.
1. Preparation
First things first, preheat your oven to 350°F (175°C). Line two large baking sheets with parchment paper to prevent the cookies from sticking. This also makes cleanup a breeze!
2. Combine Dry Ingredients
In a medium bowl, whisk together the all-purpose flour, rolled oats, baking soda, ground cinnamon, and salt. Set this bowl aside for later. Combining the dry ingredients first ensures they are evenly distributed throughout the cookie dough.
3. Cream Butter and Sugars
In a large bowl using a stand mixer or a hand mixer, beat the softened unsalted butter, light brown sugar, and granulated sugar together on medium speed until the mixture is light and fluffy. This usually takes about 2-3 minutes. This step incorporates air into the dough, which is key to a great cookie texture.
4. Add Wet Ingredients
Beat in the egg and vanilla extract until they are just combined. Scrape down the sides of the bowl as needed. Next, add the mashed ripe bananas and mix until everything is well incorporated. The mixture should be smooth and fragrant.
5. Combine Wet and Dry Mixtures
With the mixer on low speed, gradually add the dry ingredient mixture to the wet ingredients. Mix until they are just combined—be careful not to overmix! Overmixing can lead to tough cookies, and nobody wants that. A few streaks of flour are perfectly fine.
6. Bake to Perfection
Drop rounded tablespoons of dough onto your prepared baking sheets, leaving about 2 inches of space between each cookie to allow for spreading. Bake for 12-15 minutes, or until the edges are golden brown and the centers are set. Let the cookies cool on the baking sheet for a few minutes before transferring them to a wire rack to cool completely.

Expert Tips for the Best Cookies
Want to take your Banana Oatmeal Cookies from great to absolutely unforgettable? Here are a few expert tips.
- Use Very Ripe Bananas: The key to incredible banana flavor is using bananas that are heavily speckled with brown or even black spots. They are much sweeter and softer, making them perfect for baking.
- Measure Flour Correctly: To avoid dense cookies, spoon the flour into your measuring cup and then level it off with a straight edge. Don’t scoop directly from the bag!
- Don’t Overmix the Dough: Mix the dry ingredients into the wet until just combined. Overmixing develops the gluten in the flour, resulting in tougher cookies.
- Chill the Dough: If you have the time, chilling the dough for at least 30 minutes before baking can result in thicker, chewier cookies that spread less.
Fun Variations to Try
While this recipe is fantastic as is, it’s also a wonderful canvas for your culinary creativity. If you love muffins, consider trying our Peanut Butter Chocolate Chip Muffins next!
- Chocolate Chip Banana Oatmeal Cookies: A classic for a reason! Fold in 1 cup of semi-sweet chocolate chips into the dough before baking.
- Nutty Delight: Add a delightful crunch by mixing in 1/2 cup of chopped walnuts or pecans.
- Dried Fruit Twist: For extra chewiness and sweetness, add 1/2 cup of raisins or dried cranberries.
- For a Decadent Dessert: If you’re looking for something truly special for dinner, why not try this Blackened Steak and Shrimp Alfredo?

Yes, you can adapt this recipe to be gluten-free. Simply substitute the all-purpose flour with a 1-to-1 gluten-free baking flour blend and ensure that your rolled oats are certified gluten-free.
