The smell of oats toasting in a warm oven takes me straight back to childhood Saturday mornings. These ingredient oatmeal cookies are pure comfort in every bite, and they’ve become my go-to when life gets busy but I still crave something homemade and sweet.
Just three simple ingredients come together to create magic – ripe bananas, rolled oats, and whatever mix-ins your heart desires. No butter, no flour, no fuss. The bananas do all the work, binding everything into chewy, naturally sweet cookies that taste like you spent hours in the kitchen.
Started making these back in 1987 when my granddaughter couldn’t have regular cookies. Watched her little face light up when she took that first bite – pure joy over something so simple. The secret I discovered? Mash those bananas until they’re completely smooth. Makes all the difference for the perfect chewy texture.

The beauty of this recipe lies in its simplicity. You likely have everything you need in your kitchen right now. I always keep overripe bananas in the freezer specifically for moments like thesewhen the cookie craving strikes unexpectedly.
Key ingredients: Mashed banana acts as both sweetener and binding agent, while rolled oats provide that satisfying chew. Peanut butter adds richness and helps everything hold together beautifully.

|---|---|---|
| Mashed banana (3 medium) | Vanilla extract | Large mixing bowl |

| Rolled oats (2 cups) | Chocolate chips (½ cup) | Cookie scoop (optional) |
How the Magic Happens Step-by-Step
The secret to perfect texture lies in two simple techniques: mashing the bananas until mostly smooth, and letting the dough rest. That resting time allows the oats to soften and absorb all those lovely flavors.
- Mash and mix: Mash the bananas until smooth before stirring in the peanut butterthis creates the perfect base.
- Fold in oats gently: Avoid overmixing once you add the oats; just stir until everything comes together.
- Rest the dough: Those 20-30 minutes of waiting aren’t optionalthey make these cookies so tender.
- Shape with care: Use a cookie scoop for even portions, or gently press each mound into a disk for flatter cookies.
Simple Swaps and Variations
Over the years, I’ve discovered countless ways to make these 3 ingredient oatmeal cookies work for different tastes and dietary needs. The basic formula stays the same, but the possibilities feel endless.
| Instead of This | Try This | Notes |

Troubleshooting Common Issues
Even the simplest recipes have their quirks. I’ve learned these solutions through years of making these cookies with my grandchildren, who always want to helpand sometimes things don’t go exactly as planned!
- Cookies falling apart? Your bananas might not be ripe enough, or you skipped the resting timeboth are important to bind everything together.
- Too soft or mushy? Try pressing them slightly flatter before baking, or add an extra tablespoon of oats to absorb moisture.
- Not sweet enough? Choose bananas with brown spots next time, or add a handful of mini chocolate chips.
- Dry or crumbly? Make sure to measure the mashed banana after mashing, not beforeyou need the full 1½ cups.
Storage and Serving Ideas
These cookies taste wonderful warm from the oven, but they also keep beautifully for several days. I often make a double batchhalf for immediate enjoyment and half tucked away for later treat emergencies.
Pro tip: Store them in the refrigerator rather than at room temperature. The banana base stays fresher longer when kept cool, and they actually taste even better the next day.
| Storage Method | Duration | Best For |
|---|---|---|
| Airtight container, refrigerated | Up to 5 days | Daily snacking |
| Freezer bag, frozen | Up to 3 months | Meal prep or large batches |
| Room temperature (covered) | 1-2 days maximum | Immediate consumption |
Expert Says
Oatmeal cookies benefit from the unique texture and fiber content of oats, which can improve digestion and provide sustained energy. The beta-glucan in oats helps lower cholesterol levels, making these cookies a slightly better choice over traditional ones made solely with refined flour and sugar.
