Ingredients

2 large ripe bananas, mashed
Ripe bananas bring natural sweetness, moisture, and banana flavor. The riper the banana, the sweeter the cookies.
1 1/2 cups rolled oats
Rolled oats provide structure and a hearty chew. They soak up the banana for a soft crumb.
1 teaspoon ground cinnamon
Cinnamon adds a warm, cozy note that complements the banana without overpowering it.
Optional: Handful (about 1/2 cup) dark chocolate chips or chopped nuts
Chocolate chips add a rich sweetness, while chopped nuts give crunch and contrast. Add one or the other, or leave them out for a plain version.

Step-by-step Instructions

Preheat the oven to 350°F (175°C). Line a baking sheet with parchment paper or grease lightly for easy removal.
Tip: Make sure the oven is fully preheated for even baking.
In a large bowl, mix the mashed bananas, rolled oats, and ground cinnamon until well combined.
Tip: Mash the bananas thoroughly for a consistent texture; a fork works great.
If desired, fold in the dark chocolate chips or chopped nuts. Mix gently so the add-ins distribute without overworking the oats.
Tip: If using chocolate chips, a handful will create melty pockets in each cookie.
Drop spoonfuls of the mixture (about 2 tablespoons each) onto the prepared baking sheet, spacing them about 1 inch apart.
Tip: For uniform cookies, use a cookie scoop or measuring spoon.
Bake for 12-15 minutes or until the cookies are set and lightly golden. Check at 12 minutes to avoid overbaking.
Tip: They will firm up slightly as they cool, so remove when edges are just turning golden.
Allow to cool on the baking sheet for a few minutes before transferring to a wire rack to cool completely before serving.
Tip: Cooling on a rack keeps the bottoms from getting soggy.
