Step‑by‑Step Instructions for Oatmeal Cookies with 3 Ingredients
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This ensures your Oatmeal Cookies with 3 Ingredients bake evenly. While the oven heats, grab a baking sheet and line it with parchment paper for easy cleanup and to prevent sticking.
Step 2: Mash the Bananas
In a mixing bowl, take your ripe bananas and mash them with a fork until they reach a smooth and creamy consistency. This usually takes about 1-2 minutes. The mashed bananas not only add sweetness but also help bind the cookies together, giving them a delightful texture.
Step 3: Combine Ingredients
Stir in 1 cup of old-fashioned oats into the mashed bananas until well combined. If you’re adding chocolate chips for an extra touch of sweetness, fold them in gently. Mix thoroughly to ensure the oats and chocolate are evenly distributed, creating a uniform batter ready for baking.
Step 4: Scoop the Cookie Dough
Using a tablespoon, scoop out portions of the cookie dough and place them onto the lined baking sheet, spacing them two inches apart. You should aim for about 12 cookies from this recipe. This step helps ensure that each cookie has enough room to bake properly without merging into one another.
Step 5: Flatten the Cookies
Gently flatten each cookie slightly with the back of a spoon. Remember, the Oatmeal Cookies with 3 Ingredients won't spread much during baking, so this step helps achieve a nice, even shape and promotes even cooking.
Step 6: Bake to Perfection
Slide the baking sheet into your preheated oven and bake the cookies for 10-12 minutes. Keep an eye on them, and look for a golden-brown color as an indicator that they are done. The delightful aroma of baked bananas and oats will fill your kitchen!
Step 7: Cool and Serve
Once baked, allow the cookies to cool on the baking sheet for about 5 minutes. This cooling period helps them set before transferring to a wire rack. Let them cool completely before indulging in your moist, delicious Oatmeal Cookies with 3 Ingredients.

Oatmeal Cookies with 3 Ingredients Recipe FAQs
What should I look for in ripe bananas?
Absolutely! When selecting bananas, go for those with a few brown spots on their skin. The riper they are, the sweeter and softer they'll be, giving your cookies a delightful texture and flavor. Overripe bananas work best for this recipe, as they provide natural sweetness and moisture.
How should I store the cookies?
You can store your Oatmeal Cookies with 3 Ingredients in an airtight container at room temperature for up to 5 days. To keep them extra fresh, place a slice of bread in the container—this helps maintain their moisture. If you prefer them cold, they can also be stored in the fridge for about 1 week.

What if my cookies come out too gooey?
If your Oatmeal Cookies with 3 Ingredients end up too gooey, it might be due to underbaking or using too ripe bananas. Ensure you bake them until golden brown, which usually takes 10-12 minutes.
