Perfectly Simple Ingredient Oatmeal Cookies Recipe

Warm oats, toasty and sweet, smelled like comfort the first time I baked these ingredient oatmeal cookies. They came out soft in the middle, just a little crisp on the edgeslike something Grandma might’ve offered with a splash of milk before bed. Folks love these because they’re quick, healthy(ish), and still feel like a treat.

You only need ripe bananas, rolled oats, and a handful of add-ins. That’s it. They’re chewy and naturally sweet, like a cross between banana bread and a snickerdoodle. No eggs, no flour, and no fancy toolsjust a mixing bowl and a fork will do. It’s one of those healthy 3 ingredient recipes that actually satisfies a cookie craving.

I first made these during a busy spring in 2018, when I had a toddler on my hip and barely time to think. My neighbor peeked in as they baked and said, “Smells like your kitchen gave someone a hug.” What I learned? Smash those bananas well and use old-fashioned oats for the best texture. After 10+ years of writing recipes, this is still one I come back to when life’s just a little too full but I still want homemade.

Key Ingredients and Tools You’ll Need

Let’s keep it simplethe beauty of this recipe lies in using what most of us already have in the pantry and fridge:

Ingredients for oatmeal cookies displayed neatly on a wooden surface
  • Bananas: You’ll need about 3 ripe ones for mashing. The riper, the sweeter!
  • Rolled oats: Old-fashioned oats are key for a chewy texture. Avoid instant oats as they can make your cookies mushy.
  • Peanut butter: Creamy or chunky both workjust make sure it’s smooth enough to mix!
  • Optional add-ins: Vanilla extract, salt, and chocolate chips (or skip them to keep it purely 3-ingredient).

For tools, grab a mixing bowl, fork, and spatula. A cookie scoop isn’t necessary, but it makes shaping easier.

Step-by-Step: How to Make These Ingredient Oatmeal Cookies

This recipe couldn’t be simpler. Here’s how to do it:

  1. Preheat and prep: Set your oven to 350°F and line baking sheets with parchment paper for easy cleanup.
  2. Mash and mix: In a large bowl, mash the bananas until smooth with a few lumps remaining. Stir in the peanut butter and, if using, the vanilla and salt until creamy and well combined. Add the oats and any chocolate chips last, folding everything together gently.
  3. Let it rest: Cover the dough and let it sit for about 20 minutes. This helps the oats absorb moisture and prevents spreading.
  4. Scoop and bake: Drop 2-tablespoon-sized scoops of dough onto the sheet. Flatten gently if you prefer a traditional cookie shape. Bake for 10–12 minutes, until edges are golden.
  5. Cool and enjoy: Let the cookies cool for 15 minutes before transferring to a rack. They’ll firm up as they cool!

Tweaks, Tips, and Troubleshooting

Here’s how to make these cookies practically foolproof every time:

  • Don’t overmash bananas: A few lumps keep the cookies moist but not sticky.
  • Shape matters: The dough won’t spread much, so press the cookies into discs if that’s the look you prefer.
  • Resting is crucial: Skipping the resting time can lead to uneven baking or cookies that fall apart.

If your dough feels too wet, stir in an extra spoonful of oats. Too dry? Add a drizzle of peanut butter or a splash of water to balance it out.

Expert Says

Oatmeal cookies benefit from the complex carbohydrates and soluble fiber found in oats, which help regulate blood sugar and provide sustained energy. When baking, using old-fashioned rolled oats adds a chewier texture, while quick oats create a softer cookie, allowing for customization based on preference.

FAQs ( Ingredient Oatmeal Cookies )

Can I make these cookies gluten-free?

Yes, to make this recipe gluten-free, use certified gluten-free oats instead of regular oats. Make sure any additional ingredients you add are also gluten-free. This swap works well and keeps the cookies just as chewy and delicious.

How do I store the cookies to maintain freshness?

Store these cookies in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate them up to a week or freeze for up to 3 months. Just let frozen cookies thaw at room temperature before enjoying.

Can I add chocolate chips or nuts to this meal?

Absolutely! Adding chocolate chips or chopped nuts is a great way to boost flavor and texture. Just fold them into the batter gently before baking. Keep in mind that these additions may alter baking time slightly.

What is the best substitute for banana in this dish?

If you don’t have ripe bananas on hand, unsweetened applesauce is a reliable substitute. Use the same quantity to maintain moisture and binding. Both will keep cookies soft while preserving balanced sweetness.

How can I make this recipe healthier?

To enhance the health benefits, consider adding ground flaxseed or swapping regular oats for steel-cut oats if texture allows. You can also reduce any added sweeteners or use natural peanut butter without salt or sugar for added protein.
