3 Ingredient Banana Oatmeal Cookies Recipe
Introduction
These 3 Ingredient Banana Oatmeal Cookies are a simple, wholesome treat perfect for a quick snack or breakfast on the go. With just ripe bananas, rolled oats, and cinnamon, you can whip up a batch of naturally sweet, chewy cookies in under 30 minutes.

Ingredients
- 2 ripe bananas (spotty, mashed, about 200g)
- 1 cup rolled oats (old fashioned or quick cooking)
- 1 teaspoon ground cinnamon
Instructions
- Step 1: Preheat your oven to 350°F (175°C). Peel and mash the bananas in a medium bowl using a potato masher or fork until mostly smooth with only small chunks remaining.
- Step 2: Stir in the rolled oats and cinnamon. Let the mixture sit for a few minutes so the oats absorb some moisture. If the batter feels very wet, add 1 to 2 tablespoons more oats to thicken it.
- Step 3: Line a baking tray with parchment paper or a silicone baking mat to prevent sticking.
- Step 4: Drop spoonfuls of the batter onto the prepared tray. Shape each drop with your fingers into cookies approximately 3 inches wide. Keep in mind that the cookies will not spread while baking.
- Step 5: If desired, add optional toppings such as nuts, chocolate chips, or raisins before baking.
- Step 6: Bake the cookies for 17 minutes. Adjust baking time slightly for smaller or larger cookies as needed.
- Step 7: Remove cookies from the oven and let them cool slightly before enjoying.
Tips & Variations
- For extra flavor, add a handful of chopped nuts or dried fruit to the batter.
- If you prefer a sweeter cookie, mix in a tablespoon of honey or maple syrup.
- Use quick oats for a softer texture or old-fashioned rolled oats for a chewier bite.
- To make these cookies gluten-free, ensure your oats are certified gluten-free.
Storage
Store the cookies in an airtight container at room temperature for up to 3 days. For longer storage, keep them in the refrigerator for up to 1 week or freeze for up to 3 months. Reheat gently in a microwave or oven before serving if desired.

FAQs
Can I use overripe bananas?
Yes, overripe bananas are ideal for this recipe because they are sweeter and mash easily, adding natural sweetness and moisture to the cookies.
Do these cookies have a crispy texture?
These cookies are naturally soft and chewy due to the banana and oats. They do not become crispy, but will firm up slightly as they cool.

- Mash Bananas: Peel and mash the ripe bananas in a medium bowl using a potato masher or fork until well mashed with only small chunks remaining.

Notes
- For smaller cookies, reduce baking time to about 12-15 minutes.
- For larger or thicker cookies, increase baking time slightly to 18-20 minutes, but monitor closely to prevent burning.
- Ensure bananas are very ripe as they provide natural sweetness and moisture.
- You can add mix-ins or toppings such as walnuts, chocolate chips, or raisins to customize your cookies.
- Use rolled oats for best texture; instant oats may result in a different consistency.
