These cookies give you the soft, moist crumb of banana bread in a format that bakes in 10 minutes and travels without falling apart. One ripe banana, standard pantry ingredients, and a single bowl of wet ingredients is all the setup you need. If you have bananas going spotty on the counter, this is the most practical thing you can do with them.
What makes this version work
Two things actually matter here. First, the ratio of mashed banana to flour is tight enough that the cookies hold their shape on the sheet rather than spreading into puddles — but generous enough to keep them soft for days. Second, creaming the softened butter with the mashed banana before adding the sugars builds a stable base that traps air, giving the cookies a slightly lifted, cake-like texture instead of a dense, flat disc. Skip the garnish — not worth the extra dish. The cookies have enough going on with the banana and brown sugar that a drizzle or sprinkle adds nothing you’ll actually taste.
What can go wrong
- Cookies spread too thin: Your butter was too warm — closer to melted than softened. If your kitchen is hot, chill the scooped dough balls for 15 minutes before baking.
- Cookies come out gummy in the center: The banana added more moisture than expected. Bananas vary a lot. If your mashed banana looks very wet, blot it briefly with a paper towel before mixing, or add an extra tablespoon of flour.
- Bottoms brown too fast before the centers set: Dark or thin baking sheets run hot. Use a light-colored, heavy sheet or stack two pans together to insulate the bottom.
- Dough is sticky and hard to scoop cleanly: Chill the mixed dough for 20 minutes. A lightly dampened cookie scoop also releases the dough more cleanly than a dry one.
- Cookies taste flat or bland: The banana wasn’t ripe enough. The skin should be heavily speckled or mostly brown — a just-yellow banana won’t give you enough sweetness or flavor.
Storage and make-ahead
Cooled cookies keep well in an airtight container at room temperature for up to 4 days — they actually soften slightly by day two, which most people prefer. For longer storage, freeze the baked cookies in a single layer first, then transfer to a zip bag; they keep for up to 2 months and thaw at room temperature in about 20 minutes. If you want to work ahead, the raw dough can be scooped into balls and frozen on a sheet, then stored in a bag for up to 6 weeks — bake straight from frozen at 350°F and add 2 to 3 minutes to the bake time.
Banana Bread Cookies
Equipment
- Mixing Bowls
- Whisk
- Baking sheet
- Parchment Paper
- Cookie scoop
- Cooling Rack
Ingredients
- 1 cup ripe banana mashed
- ½ cup unsalted butter softened
- ½ cup granulated sugar
- ½ cup brown sugar packed
- 1 teaspoon vanilla extract
- 1 large egg
- 1 ½ cups all-purpose flour
- 1 teaspoon baking soda
- ½ teaspoon salt
- 1 cup chopped walnuts optional
Instructions
- Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
- In a large mixing bowl, whisk together the mashed banana and softened butter until smooth and creamy.
- Add the granulated sugar, brown sugar, and vanilla extract to the banana mixture and whisk to combine. Then beat in the egg until fully incorporated.
- In a separate bowl, mix the flour, baking soda, and salt. Gradually add the dry ingredients to the wet ingredients, stirring until just combined. Avoid over-mixing.
- Fold in the chopped walnuts if using.
- Using a cookie scoop, drop dough onto the prepared baking sheet, leaving about 2 inches apart between each cookie.
- Bake for 8-10 minutes or until the edges are golden brown. Allow the cookies to cool on the baking sheet for 5 minutes before transferring them to a cooling rack to cool completely.
Notes
- For a more intense banana flavor, use overripe bananas.
- You can substitute walnuts with pecans or omit them entirely for nut-free cookies.

Common questions
Can I use frozen bananas instead of fresh overripe ones?
Yes, frozen bananas work well here. Thaw them completely, then drain off the liquid that collects before mashing — skipping that step is what makes cookies spread or turn gummy.
Do I need to use a cookie scoop, or can I just use a spoon?
A spoon works fine. Aim for portions roughly the size of a golf ball, about 1.5 tablespoons of dough each, so the cookies bake evenly and finish at the same time.
Can I add chocolate chips instead of walnuts?
Absolutely — semi-sweet chips are a natural fit with the banana flavor. Use the same quantity as the walnuts, about 1 cup, and fold them in at the same stage.
How do I know when the cookies are actually done if the tops still look pale?
Watch the edges, not the tops — they should be set and just turning golden while the center still looks slightly underdone. The cookies firm up as they cool on the pan during that 5-minute rest, so pulling them a little early is correct.
