- Banana – Provides natural sweetness and moisture; overripe bananas are perfect for enhancing flavor.
- Cocoa Powder – Adds a rich chocolatey essence; opt for unsweetened cocoa to keep the taste balanced.

Step‑by‑Step Instructions for Chocolate Oat Cookies
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C). While the oven warms up, line a baking sheet with parchment paper to prevent the cookies from sticking. This simple step is essential for creating the perfect base for your delicious chocolate oat cookies, ensuring they bake evenly and release flawlessly.
Step 2: Mash the Bananas
In a mixing bowl, take a few ripe bananas and mash them until smooth; this should take about 2-3 minutes. The bananas not only provide natural sweetness but also moisture, which is crucial for the texture of your chocolate oat cookies. Aim for a creamy consistency, free of lumps, to ensure every bite is delightful.
Step 3: Mix the Ingredients
Add the rolled oats and cocoa powder to the mashed bananas, stirring well to combine. This mixture should be thick but cohesive, resembling a dough-like consistency after a minute or so of mixing. Ensure the oats are evenly coated in the cocoa and banana mixture; this will amplify the chocolate flavor in your cookies.
Step 4: Scoop the Batter
Using a tablespoon or cookie scoop, portion out mounds of the cookie batter onto the prepared baking sheet. Leave about 1-2 inches of space between each scoop to allow for spreading during baking. This step ensures your chocolate oat cookies maintain their shape while baking, offering that perfect chewy texture we all love.
Step 5: Bake to Perfection
Bake the cookies in your preheated oven for 12-15 minutes, or until they are firm to the touch and slightly set around the edges. You’ll know they are ready when they begin to firm up and slightly crack on top, providing a tantalizing hint of the chewy goodness waiting inside.
Step 6: Cool and Serve
Once baked, remove the chocolate oat cookies from the oven and allow them to cool on the baking sheet for about 5 minutes before transferring them to a wire rack. This cooling period helps the cookies maintain their chewy texture while also ensuring they’re easy to handle. Once cooled, delight in your homemade treats!

Make Ahead Options
These Chocolate Oat Cookies are perfect for meal prep enthusiasts looking to save time during busy weeks! You can mash the bananas and combine them with the oats and cocoa powder up to 24 hours in advance. Simply cover the mixed batter tightly and refrigerate it to maintain freshness and prevent browning. When you’re ready to bake, scoop the chilled batter onto a prepared baking sheet and bake as directed. Storing the cookies in an airtight container will keep them soft for up to 5 days at room temperature. This make-ahead method ensures you have a healthy and delicious snack ready to indulge in with minimal effort!
Storage Tips for Chocolate Oat Cookies
Room Temperature: Store your chocolate oat cookies in an airtight container at room temperature for up to 5 days to maintain their softness and chewy texture.
Fridge: If you prefer a slightly firmer cookie, you can refrigerate them for up to 7 days in an airtight container. This option also helps maintain freshness.
Freezer: For longer storage, freeze the cookies in a single layer, then transfer to a freezer-safe bag or container for up to 2 months. Thaw at room temperature before enjoying.
Reheating: To bring back their delightful chewiness, reheat cookies in the microwave for about 10-15 seconds, or in the oven at 300°F (150°C) for a few minutes.

Chocolate Oat Cookies Recipe FAQs
What kind of oats should I use for Chocolate Oat Cookies?
Absolutely! For a gluten-free version, it’s essential to use certified gluten-free rolled oats. These oats provide the best texture and structure for your cookies, ensuring that they are both chewy and satisfying.
How should I store my Chocolate Oat Cookies?
I recommend storing your chocolate oat cookies in an airtight container at room temperature for up to 5 days. This keeps them soft and chewy. If you live in a warmer climate, storing them in the fridge for up to 7 days is a great alternative to maintain freshness.
Can I freeze Chocolate Oat Cookies?
Yes, you can! To freeze them, place the cookies in a single layer on a baking sheet and freeze for about 1-2 hours until firm. Then, transfer them to a freezer-safe bag or container, where they can last up to 2 months. When you’re ready to enjoy, simply thaw them at room temperature, or microwave for 10-15 seconds for a quick treat!
What should I do if my cookie batter is too dry?
If your batter feels too dry, it might be due to the bananas not being ripe enough, or you may need to add a little moisture. Simply mash another half banana into the mix. Alternatively, you can stir in a teaspoon of almond milk or water to achieve a better consistency. Mixing should be gentle; remember, you want that chewy texture!
Are Chocolate Oat Cookies suitable for dogs?
While the main ingredients are dog-friendly, I suggest avoiding adding any sweetener like chocolate chips, as chocolate is harmful to dogs. Always check with your veterinarian before sharing human snacks with your furry friends!
Can I substitute bananas in the Chocolate Oat Cookies?
Most definitely! If you want a different flavor or need a banana substitute, unsweetened applesauce works beautifully. You can also try using pumpkin puree for a seasonal twist that still provides moisture and sweetness!
