3-Ingredient Gluten-Free Chocolate Oat Cookies
Discover the secret to effortless baking with this incredibly simple cookie recipe!
For the Cookies
• Oats – Provide structure and a chewy texture; rolled oats yield the best results.
• Banana – Acts as a natural sweetener and binder; unsweetened applesauce can be used as a tasty substitute.
• Cocoa Powder – Adds a deep, rich chocolate flavor; opt for unsweetened to maintain a well-balanced sweetness.
Step‑by‑Step Instructions for 3-Ingredient Gluten-Free Chocolate Oat Cookies
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While your oven warms up, prepare a baking sheet by lining it with parchment paper, ensuring that your cookies won’t stick and will easily slide off once baked. This is your first step towards creating delicious 3-Ingredient Gluten-Free Chocolate Oat Cookies!
Step 2: Mash the Banana
In a mixing bowl, take a ripe banana and use a fork to mash it until it becomes a smooth consistency, about 1-2 minutes. This mashed banana serves as the natural sweetener and binder for your cookies. Aim for a creamy texture as this will help combine all the ingredients seamlessly in the next steps.
Step 3: Combine Ingredients
Next, stir in rolled oats and unsweetened cocoa powder to the mashed banana. Mix everything together vigorously for about 2-3 minutes until well combined and no dry cocoa powder or oats remain visible. This step creates the base for your gluten-free chocolate oat cookies, infusing the mixture with rich chocolate flavor.
Step 4: Scoop onto Baking Sheet
Using a tablespoon, scoop out portions of the cookie mixture and place them onto the lined baking sheet, spacing each cookie about 2 inches apart. Gently flatten them slightly with the back of your spoon for even baking. This will help them maintain their shape while baking, ensuring each bite is delicious.
Step 5: Bake the Cookies
Slide the baking sheet into the preheated oven and bake your cookies for 10-12 minutes. You’ll know they’re ready when the edges start to firm up, although the centers may still appear soft. Keep an eye on them to avoid overbaking, which could lead to a harder texture.
Step 6: Cool and Transfer
Once baked, remove the baking sheet from the oven and allow the cookies to cool for 5 minutes while still on the sheet. This waiting time is crucial as it lets them set properly. After cooling, transfer the cookies to a wire rack to cool completely, allowing them to reach the perfect chewy consistency before indulging.

Make Ahead Options
These 3-Ingredient Gluten-Free Chocolate Oat Cookies are perfect for meal prep enthusiasts! You can mash the ripe banana, mix in the oats, and cocoa powder up to 24 hours in advance; simply store the prepared dough in an airtight container in the refrigerator. When you’re ready to bake, scoop tablespoon-sized portions onto a lined baking sheet and bake as directed for a fresh, warm treat. Additionally, these cookies can be stored in an airtight container at room temperature for up to 7 days after baking, ensuring you always have a delicious snack ready to go. Just remember, to maintain their chewy texture, allow them to cool completely before storing!
Storage Tips for 3-Ingredient Gluten-Free Chocolate Oat Cookies

Fridge: If you want to prolong their freshness, you can store the cookies in the fridge for up to 2 weeks. Ensure they are well-wrapped to prevent moisture.

3-Ingredient Gluten-Free Chocolate Oat Cookies Recipe FAQs
How do I know if my banana is ripe enough for the cookies?
Absolutely! Look for bananas that have brown spots on the peel—this indicates they are very ripe and sweet. If your banana is still mostly yellow with only a few freckles, give it a couple of days at room temperature to become perfectly sweet and ready for baking.
How should I store the cookies after baking?
Very! Store your cookies in an airtight container at room temperature for up to 1 week. If you prefer a fresher option, you can keep them in the fridge for up to 2 weeks. This helps maintain the chewy texture, but they may lose a bit of warmth.
Can I freeze these cookies, and if so, how?
Yes, definitely! To freeze your cookies, lay them out in a single layer on a baking sheet and freeze until solid, about 1-2 hours. Then, transfer the cookies to a freezer-safe bag or container, separating layers with parchment paper for easy access. They can be frozen for up to 3 months. Thaw at room temperature, or pop them in the microwave for about 10-15 seconds for a warm treat!
What should I do if my cookie dough is too dry or crumbly?
If your dough feels dry, don’t worry! You can add a tiny splash of water or a bit more mashed banana to bring it together. If it’s too sticky, try adding a touch more cocoa powder or oats until you reach a nice consistency. Remember to mix gently!
Are these cookies safe for my gluten-free friends?
Absolutely! Since the main ingredients—oats, bananas, and cocoa powder—are naturally gluten-free, you can confidently serve these cookies to your gluten-sensitive friends. Just ensure that all your ingredients are labeled gluten-free, especially oats, as they can sometimes be cross-contaminated during processing.
Can I use other sweeteners instead of banana?
Yes, you can! For a different twist, consider substituting ripe bananas with unsweetened applesauce or almond butter. If using applesauce, start with a 1:1 ratio and adjust the oats if needed to arrive at the right dough consistency. Each substitute brings its unique flavor while keeping the recipe gluten-free!
