Step‑by‑Step Instructions for Healthy Banana Oatmeal Cookies
Step 1: Prepare the Bananas
Start by peeling 2–3 ripe bananas and placing them in a large mixing bowl. Use a fork to mash the bananas until they are smooth and creamy, with no lumps remaining. This should take about 2–3 minutes. The riper the bananas, the sweeter your Healthy Banana Oatmeal Cookies will be, so aim for those with plenty of brown spots!
Step 2: Mix Ingredients
Add 1 ½ cups of gluten-free rolled oats and 1 teaspoon of vanilla extract to the mashed bananas. If you’re including cinnamon, add ½ teaspoon now, along with a pinch of salt to enhance the sweetness. Stir the mixture thoroughly with a spatula until all ingredients are well combined, creating a sticky and cohesive dough—about 2 minutes of mixing should do the trick.
Step 3: Add Optional Items
If you want to customize your Healthy Banana Oatmeal Cookies, this is the time to add in any extras! Gently fold in ½ cup of your choice of nuts, chocolate chips, or dried fruits into the mixture. Ensure that these additions are evenly distributed throughout the dough, which should take about 1 minute, maintaining that delightful chewy texture.
Step 4: Shape Cookies
Line a baking sheet with parchment paper to prevent sticking. Using a tablespoon or a cookie scoop, portion out the cookie dough onto the prepared baking sheet, leaving space between each mound. Flatten each cookie slightly with the back of a spoon to ensure even baking. You should have about 10-12 cookie dough mounds ready for the next step.
Step 5: Bake/Air Fry
Preheat your oven to 350°F (175°C) or your air fryer to 320°F (160°C). Bake the cookies in the oven for about 12-15 minutes, or air fry them for about 10 minutes. Keep an eye on your Healthy Banana Oatmeal Cookies; they should turn golden brown at the edges and look set in the center when done.
Step 6: Cool
Once baked, remove the cookies from the oven or air fryer and let them sit on the baking sheet for about 5 minutes. This will allow them to firm up slightly. Then, transfer the cookies to a wire rack to cool completely. They will become even chewier as they cool, ready to be enjoyed!

Expert Tips for Healthy Banana Oatmeal Cookies
• Ripe Bananas Are Key: Use very ripe bananas with brown spots for maximum sweetness and moisture in your Healthy Banana Oatmeal Cookies.
• Don’t Overmix: Gently combine the ingredients to avoid tough cookies. Overmixing can change the delightful chewy texture!
• Check Air Fryer Settings: Cooking times may vary significantly in an air fryer, so keep an eye on your cookies as they bake to prevent overcooking.
• Experiment with Add-Ins: Feel free to fold in various nuts, chocolate chips, or dried fruits. These additions can elevate flavor and texture without compromising the healthy aspect.
• Cool for Best Texture: Allow your cookies to cool completely on a wire rack; they will firm up and develop a delicious chewiness, making them even more enjoyable!
How to Store and Freeze Healthy Banana Oatmeal Cookies

What’s the best way to store leftover cookies?
