Grandma’s 3-Ingredient Soft Banana Bread Cookies

These soft, comforting banana bread cookies are the kind of recipe handed down at family kitchen tables. Made with just ripe bananas, rolled oats, and a touch of cinnamon, they bake into tender, slightly chewy cookies that smell like a warm loaf straight from the oven. The aroma is sweet and gently spiced, the texture is soft with a satisfying oat chew, and the flavor tastes like banana bread in cookie form. They are perfect for a quick breakfast nibble, an after-school snack, or a simple dessert when you want something wholesome without fuss.

Ingredients

2 large ripe bananas, mashed
Ripe bananas are sweeter and mash easily, giving natural sweetness and moisture to the cookies.
1 1/2 cups rolled oats
Rolled oats provide structure and chewy texture. Old-fashioned rolled oats work best for a nice bite.
1 teaspoon ground cinnamon
Adds warm, aromatic spice that complements the banana without overpowering it.
Optional: Handful (about 1/2 cup) dark chocolate chips or chopped nuts
Folded in for extra richness or crunch. Use dark chocolate chips for a deep cocoa note or chopped nuts for texture.

Step-by-step Instructions

Preheat the oven to 350°F (175°C). Line a baking sheet with parchment paper or grease it lightly.
Tip: Parchment makes cleanup easy and helps cookies release cleanly.
In a large bowl, mix the mashed bananas, rolled oats, and ground cinnamon until well combined.
Tip: Mash the bananas until mostly smooth for a uniform texture, or leave small chunks for a more rustic bite.
If desired, fold in the dark chocolate chips or chopped nuts.
Use a gentle folding motion so the mixture stays light and evenly mixed.
Drop spoonfuls of the mixture (about 2 tablespoons each) onto the prepared baking sheet, spacing them about 1 inch apart.
Tip: Slightly flatten each mound with the back of the spoon if you prefer a more cookie-like shape.
Bake for 12-15 minutes or until the cookies are set and lightly golden.
The center should be firm to the touch but still soft. Baking time varies by oven; check at the 12-minute mark.
Allow to cool on the baking sheet for a few minutes before transferring to a wire rack to cool completely.
Cooling a little on the sheet helps them finish setting without breaking apart.

Tips, Storage & Variations

Tips
- Use very ripe bananas with brown spots for best sweetness and soft texture.
- If you prefer a chewier cookie, press the dough slightly less before baking. For a flatter cookie, flatten each scoop a bit more.
- For smaller cookies, use 1 tablespoon scoops and reduce baking time by 1 to 2 minutes.
Storage
- Store cooled cookies in an airtight container at room temperature for up to 3 days.
- Refrigerate for up to 7 days if your kitchen is warm or if you used chopped nuts.
Freezing
- Freeze baked cookies in a single layer on a sheet pan until firm, then transfer to a freezer-safe bag for up to 2 months. Thaw at room temperature or warm briefly in a low oven.
Flavor variations using only existing ingredients
- Chocolate chip banana cookies: Fold in the optional dark chocolate chips for melty pockets of chocolate.
- Nutty banana cookies: Stir in the optional chopped nuts for crunch and a toasty flavor.
- Extra cinnamon: Increase the cinnamon slightly for a warmer, more aromatic cookie.
