Step‑by‑Step Instructions for 4-Ingredient Gluten-Free Chocolate Oat Cookies
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C), which is the perfect temperature for baking these delightful Chocolate Oat Cookies. While the oven warms up, line a baking sheet with parchment paper to prevent the cookies from sticking and ensure even baking.
Step 2: Mash the Banana
In a medium mixing bowl, take one ripe banana and mash it with a fork until it’s smooth and creamy. This will serve not only as a natural sweetener but also as a binder for your cookie mixture. A well-mashed banana will yield cookies that are moist and chewy.
Step 3: Combine Nut Butter
Next, stir in your choice of nut butter—be it almond or peanut—into the mashed banana. Mix thoroughly until the two ingredients are well combined and the mixture is smooth. This step adds delicious creaminess and healthy fats, making every bite of your Chocolate Oat Cookies even better.
Step 4: Add Cocoa Powder
Once your nut butter is fully incorporated, sift in the unsweetened cocoa powder. Gently fold the cocoa into the banana-nut butter mixture until it’s evenly distributed and you see a rich chocolate hue. This is where the delightful flavor of your cookies will stem from, enhancing their chocolatey goodness.
Step 5: Incorporate Oats
Now, add the gluten-free oats to the bowl and mix everything until the oats are fully coated with the chocolatey mixture. This step gives your cookies their classic chewy texture while keeping them gluten-free. Ensure that no dry oats are visible, creating a uniform dough.
Step 6: Scoop Cookie Portions
Using a tablespoon or cookie scoop, portion out the dough onto your prepared baking sheet, spacing them about two inches apart. This will allow the cookies to spread and bake evenly. Each scoop will form the base of your delicious Chocolate Oat Cookies, ready to be baked.
Step 7: Bake the Cookies
Place the baking sheet in the preheated oven and bake for 10-12 minutes. You’ll know your cookies are ready when the edges look set, and the tops are no longer wet. Keep an eye on them to avoid overbaking, ensuring they remain chewy and delicious.
Step 8: Cool and Enjoy
After baking, remove the sheet from the oven and allow the cookies to cool on the baking sheet for about five minutes. This helps them firm up slightly before transferring them to a wire rack. Let them cool completely, and prepare yourself for the tasty treat that is your 4-Ingredient Gluten-Free Chocolate Oat Cookies!

How to Store and Freeze Chocolate Oat Cookies
Airtight Container: Store the cookies in an airtight container at room temperature for up to 5 days to keep them fresh and chewy.
Refrigerator: If you need them to last a bit longer, you can refrigerate them for up to a week; just be sure to let them come to room temperature before enjoying.
Freezer: For longer storage, freeze the cookies in a single layer on a baking sheet before transferring them to a freezer-safe bag for up to 3 months.
Reheating: To enjoy a warm treat, reheat in the microwave for about 10-15 seconds, or place in an oven at 350°F (175°C) for a few minutes until warmed through.

4-Ingredient Gluten-Free Chocolate Oat Cookies Recipe FAQs
What type of oats should I use for these cookies?
You should opt for gluten-free oats to ensure that your chocolate oat cookies remain safe for those with gluten sensitivities. Look for certified gluten-free labels to be sure. Regular rolled oats or quick oats can work, but ensure they are labeled gluten-free to avoid cross-contamination.
How should I store my chocolate oat cookies?
To keep your cookies fresh, store them in an airtight container at room temperature for up to 5 days. If you prefer longer storage, refrigerate them for up to a week, allowing them to come back to room temperature for the best taste.
Can I freeze the cookies? If so, how?
Absolutely! To freeze your cookies, start by placing them in a single layer on a baking sheet and let them freeze until solid. After that, transfer them to a freezer-safe bag or container, ensuring you remove as much air as possible. They can be stored in the freezer for up to 3 months. When you’re ready to enjoy, just thaw them at room temperature or reheat them gently.
How do I prevent my cookies from becoming dense?
To achieve the perfect chewy texture, avoid overmixing the dough once you add the oats. Mix just until everything is combined, and make sure you’re using a very ripe banana for natural sweetness and moisture. If you notice a dense cookie, it may be due to overmixing, so be gentle!
Are these cookies safe for people with nut allergies?
If you want to make these cookies nut-free, simply swap the nut butter with sunflower seed butter. This alternate option not only provides a similar texture but also keeps the recipe delicious and safe for those with nut allergies.
Can I use other sweeteners instead of banana?
Yes! If you’re looking for alternatives, you can substitute the ripe banana with unsweetened applesauce in equal amounts. This will help maintain moisture and sweetness while keeping the cookies gluten-free and delicious. Just note that the flavor will slightly change!
