There I was, staring into an empty pantry, craving something sweet but refusing to hit the store for the third time that week. That's when the idea hit me: what if I could make cookies with just three things I already had? No fancy flours, no eggs, no butter. Just ripe bananas, oats, and a handful of chocolate chips. The result? These Healthy 3 Ingredient Cookies – soft, chewy, and dangerously easy to whip up.

Whether you're a seasoned baker or a total newbie, this one's foolproof. You'll be amazed at what three humble ingredients can do.
Why You'll Love This Recipe
About the Ingredients
2 large ripe bananas (about 230g peeled)
The riper, the better – they mash easily and add natural sweetness. If you only have slightly green ones, roast them in a 350°F (175°C) oven for 15 minutes to speed up ripening.
1 cup (80g) old-fashioned rolled oats
Use certified gluten-free oats if needed. Quick oats work too but yield a softer cookie; steel-cut won't soften enough, so stick with rolled or quick.
1/3 cup (60g) dark chocolate chips (or chopped dark chocolate)
Dark chocolate (70% cacao) keeps sugar low. Swap with raisins, dried cranberries, or chopped nuts for a different twist.
Tips & Tricks
- Mash bananas thoroughly – no lumps – to ensure even sweetness and a uniform texture. Chunks can cause soggy spots.
- Let the dough rest for 5 minutes before scooping. The oats absorb moisture, making the dough easier to handle and the cookies chewier.
- Don't overbake. They're done when the edges are golden brown and the centers look slightly underdone – they'll set as they cool.
Pro Tips
Step-by-Step Instructions
1. Preheat and prep
Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper or a silicone mat.
2. Mash bananas
In a medium bowl, mash the bananas with a fork until smooth. There should be no large chunks – this ensures even sweetness and texture.
3. Mix in oats
Stir in the rolled oats until fully combined. Let the mixture sit for 5 minutes so the oats can absorb moisture and soften.
4. Fold in chocolate
Gently fold in the chocolate chips. Reserve a few chips to press onto the tops of the cookies for a prettier look.
5. Scoop and shape
Scoop out rounded tablespoons of dough (about 1.5 inches). Place on the prepared sheet, spacing them 2 inches apart. Flatten each slightly to about 1/2 inch thick.
6. Bake until golden
Bake for 12-15 minutes, or until the edges are golden brown and the centers look just set. They will firm up as they cool.
7. Cool and enjoy
Let the cookies cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely. Enjoy warm or at room temperature.
Delicious Variations
Peanut Butter Swirl
Add 2 tablespoons of peanut butter when mashing the bananas for a nutty flavor.
Berry Burst
Swap chocolate chips for 1/2 cup fresh or frozen blueberries (thawed) – they'll add juicy pockets.
Spiced Apple
Add 1/4 teaspoon cinnamon and 1/4 cup finely chopped dried apple for a fall twist.
How to Store Healthy 3 Ingredient Cookies
Refrigerator
Store in an airtight container in the fridge for up to 5 days. They stay soft and chewy.
Freezer

Reheating
Reheat in a toaster oven or microwave for 10-15 seconds to bring back that fresh-baked warmth.
Frequently Asked Questions
Q: Can I use quick oats instead of rolled oats?
Yes, quick oats work fine and give a softer, more tender cookie. They absorb liquid faster, so you may need to reduce the resting time to 3 minutes.
Q: Can I make these cookies without bananas?
Bananas are essential for binding and sweetness. You can substitute with 1/2 cup unsweetened applesauce plus 1 extra tablespoon oats, but the texture will be different and less chewy.
Q: Are these cookies gluten-free?
Yes, if you use certified gluten-free oats. Regular oats are often cross-contaminated, so check the label if you're sensitive.
Q: How do I know when the cookies are done?
The edges will be golden brown and the centers will look slightly underdone. They'll set as they cool – overbaking makes them dry.
