Key Ingredients & Tools You’ll Need
The true beauty of this recipe lies in its simplicity. You probably have everything sitting in your pantry right now, just waiting to be transformed into something wonderful.
The Magic Three: Ripe bananas are your secret weapon here – the spottier, the better! They provide all the sweetness and binding power. Creamy peanut butter adds richness and helps hold everything together. Old-fashioned rolled oats give that perfect chewy texture we all crave.
For tools, you’ll just need a mixing bowl, a fork for mashing, and a couple of baking sheets. I love using a cookie scoop for uniform sizes, but a spoon works perfectly too.
| Ingredient | Easy Swaps | Why It Works |
|---|---|---|
| Bananas | Applesauce, pumpkin puree | Natural sweetener and binder |
| Peanut butter | Almond butter, sunflower seed butter | Adds richness and protein |
| Rolled oats | Quick oats (texture will differ) | Creates chewy, hearty texture |
Step-by-Step Instructions
Here’s where the magic happens – and trust me, it’s almost foolproof! The key is letting that cookie dough rest. I learned this trick after batch number fifteen, and it makes all the difference in texture.
Start by mashing your bananas until they’re mostly smooth with just a few happy lumps. Stir in the peanut butter until the mixture is creamy and smooth. Gently fold in the oats, ensuring they are well-coated but not overmixed.
The Secret Step: Let that dough rest for 20-30 minutes! This allows the oats to absorb moisture and gives you cookies that hold together beautifully instead of crumbling apart.
- Scoop 2-tablespoon portions onto parchment-lined sheets
- Press down slightly if you prefer flatter cookies
- Bake at 350°F for 10-12 minutes until edges are golden
- Cool on the pan for 15 minutes before transferring

After years of perfecting these delightful cookies, I’ve discovered some game-changing tricks that will make your batch even better. While chocolate chips are technically optional, they’re a non-negotiable in my household – my kids would revolt!
Pro Tip: If your bananas aren’t quite ripe enough, pop them in a 300°F oven for 10-15 minutes until the skins darken. They’ll be perfectly sweet and mashable.
Want to jazz things up? Try adding a pinch of cinnamon, a handful of raisins, or even some shredded coconut. I’ve also made them with mini dark chocolate chips for a more grown-up treat.

Expert Insight: The Science Behind Simple Ingredient Oatmeal Cookies

FAQs ( Ingredient Oatmeal Cookies )
Can I substitute the banana in this recipe?
Yes, you can replace banana with unsweetened applesauce or pumpkin puree in equal amounts. However, banana provides the best binding and natural sweetness. If using applesauce, add a pinch of cinnamon for extra flavor.
Store this recipe in an airtight container at room temperature for up to 5 days. For longer storage, freeze them for up to 3 months. They taste best within the first 2-3 days when they maintain their chewy texture.
What type of oats work best?
Old-fashioned rolled oats give the best texture and hold their shape during baking. Quick oats work too but create a softer, less chewy cookie. Avoid steel-cut oats as they won’t soften enough during the short baking time.
Can I add chocolate chips or other mix-ins?
Absolutely! Fold in 1/4 cup of mini chocolate chips, dried cranberries, or chopped nuts after mixing the base ingredients. Keep additions to 1/4 cup maximum to maintain the simple structure and prevent spreading issues.
This usually happens when the banana isn’t ripe enough or the mixture is too dry. Use very ripe, spotted bananas for maximum binding power. Let the dough rest for 10 minutes before baking to allow oats to absorb moisture.
