Name: Quick 3-Ingredient Banana Cookies Recipe
Prep time: 5 min
Cook time: 12 min
Total time: 17 min
Ingredients: 3 large ripe bananas; 2 cups rolled oats; ½ cup dark chocolate chips

These quick 3-ingredient banana cookies turn ripe bananas, rolled oats, and chocolate chips into a warm little treat with almost no effort. They come together in one bowl and bake in about twelve minutes, so they are a solid choice on a night when you want something homemade but can’t face a long ingredient list.

The texture lands somewhere between a soft baked oatmeal cup and a chewy cookie, and the banana does all the sweetening so you don’t need to pull out the sugar canister.

Why These Banana Cookies Work

The banana brings moisture, natural sweetness, and holds the whole thing together. No egg, no flour, no added sugar, yet the cookies set up with golden edges and a tender middle.

Oats give them a satisfying chew, and dark chocolate chips melt into little pockets that cut the sweetness just enough. Because there are only three ingredients, the flavor of each one comes through clearly, which is why a spotty, overripe banana matters so much here.

Ingredients

3 large ripe bananas: the spottier the better for natural sweetness and moisture.
2 cups rolled oats: use old-fashioned rolled oats for a chewy texture; quick oats will make them softer and a bit mushier.
½ cup dark chocolate chips: semi-sweet or milk chocolate also work if that is what you have.

Variations / Substitutions

Chocolate chips: swap in an equal amount of chopped walnuts, raisins, or dried cranberries for a different spin.
Oats: certified gluten-free oats keep these entirely gluten-free if needed.
Dairy-free: use dairy-free chocolate chips and the cookies are naturally vegan.

How to Make 3-Ingredient Banana Cookies

Step 1: Mash the Bananas

Preheat your oven to 350°F (175°C). Peel the 3 bananas and drop them into a medium bowl. Mash with a fork until they are mostly smooth with only a few small lumps left, about 30 seconds.

Step 2: Mix in the Oats and Chocolate Chips

Add the 2 cups of rolled oats and the ½ cup of chocolate chips to the mashed banana. Stir with a spatula until everything is evenly coated and no dry oat patches remain, about 1 minute. The dough will be thick and sticky, which is exactly what you want.

Step 3: Scoop and Bake the Cookies

Line a baking sheet with parchment paper. Use a cookie scoop or a tablespoon to drop rounded mounds of dough onto the sheet, spacing them about 2 inches apart; you should get roughly 12 cookies. Bake for 12 to 15 minutes, until the edges are lightly golden and the tops look set and dry.

Step 4: Cool and Serve the Cookies

Let the cookies cool on the baking sheet for 5 minutes before transferring them to a wire rack. They will be soft right out of the oven but firm up as they cool. Serve warm for chewy edges and pockets of melted chocolate, or let them come to room temperature.

Tips for the Best Banana Cookies

Use very ripe bananas.: Look for peels covered in brown spots or even turning black. Underripe bananas don’t have enough sweetness or moisture.
Don’t overmix.: Stir just until the oats and chips are incorporated so the cookies stay tender.
For thicker cookies, keep the mounds tall: on the baking sheet. For a flatter, crispier edge, press them down lightly with the back of a fork before baking.
Let them cool completely before storing: to keep them from turning soft or sticky in the container.

Storing Leftover Banana Cookies

Refrigerate:: Keep the cookies in an airtight container at room temperature for up to 3 days, or refrigerate them for up to a week. They are chewiest at room temperature but hold up fine in the fridge.
Reheating:: Zap a chilled cookie in the microwave for about 10 seconds to soften it up again.

Frequently Asked Questions

Can I use quick oats instead of rolled oats?

Yes, but the cookies will be softer and less chewy. Rolled oats give you that sturdy, toothsome bite.

Can I freeze the dough?

Yes. Scoop the dough onto a parchment-lined sheet, freeze until solid, then transfer the frozen mounds to a zip-top bag. Bake straight from the freezer, adding 2 to 3 minutes to the bake time.

How do I make the cookies sweeter without adding processed sugar?

Use the ripest bananas you can find, or pick a sweeter add-in like milk chocolate chips instead of dark. You can also stir in a tablespoon of maple syrup if you don’t mind bending the three-ingredient rule a little.

Why did my cookies turn out dry?

The bananas may not have been ripe enough. Very spotty bananas carry the moisture the recipe needs. If your dough seemed dry before baking, an extra spoonful of mashed banana or a splash of milk can help.
