Chewy banana bread chocolate chip cookies — the best thing to do with overripe bananas

If you have overripe bananas on your counter and you are about to make banana bread — stop. Just for a second. Because these chewy banana bread chocolate chip cookies deserve your full attention before you make any decisions.

Everything you love about banana bread — that warm, sweet, deeply banana flavor with soft, moist texture — packed into a chewy chocolate chip cookie format with pools of melty dark chocolate and a sprinkle of flaky sea salt on top.

These cookies are the kind of thing that disappears from the counter within hours of being baked. Not an exaggeration. This has been tested repeatedly.

The best part is that this recipe is genuinely simple. One bowl, no mixer required, basic pantry ingredients, and about 30 minutes of your time including the chill.

If you have been looking for a reason to let your bananas get properly overripe instead of eating them while they are still yellow — this is that reason. Let's get into it.

Why you'll love this recipe

• That banana bread flavor in every bite. The overripe bananas do not just add moisture — they add that distinctive warm, sweet banana flavor that makes every single cookie taste like your favorite banana bread in cookie form.
• Perfectly chewy with crispy edges. The combination of brown butter, brown sugar, and banana gives you that ideal cookie texture — chewy and soft in the center with slightly crispy golden edges that add an incredible contrast.
• One bowl, no mixer needed. Everything comes together in a single mixing bowl with a wooden spoon or rubber spatula. No stand mixer, no hand mixer, no complicated equipment. Clean up is minimal and the recipe is genuinely accessible to anyone.
• Ready in under an hour. Including the chill time these cookies are done in under 60 minutes. And the chill time is not optional but it is passive — you are not actually doing anything during those 30 minutes.
• The flaky sea salt finish is a game changer. A pinch of flaky sea salt on top of each cookie right before baking elevates these from great to genuinely exceptional. The salt amplifies the chocolate, balances the sweetness, and adds a pop of flavor that makes every bite more interesting.
• Great use for overripe bananas. Finally — something to do with those too-far-gone bananas that is not banana bread. Not that banana bread is bad. But variety is the spice of life. IMO these cookies win in a direct comparison.

Ingredients with key notes

• 2 very ripe bananas, mashed — you want bananas that are deeply speckled brown or almost entirely black. The riper the banana the sweeter and more intensely flavored it is, which translates directly into more flavor in the cookies. Measure after mashing — you want about 3/4 cup of mashed banana.
• 1/2 cup unsalted butter — browned. This is the step that takes these cookies from good to extraordinary. Browning the butter takes about 5 minutes and creates a deep, nutty, caramel-like flavor that pairs incredibly well with the banana and chocolate. Do not skip it. Instructions are in the recipe steps below.
• 3/4 cup brown sugar, packed — brown sugar gives the cookies a deeper, more caramel-like sweetness and contributes to that chewy texture. Dark brown sugar gives an even more intense molasses flavor if you want to go that route.
• 1/4 cup granulated sugar — the combination of both sugars gives you the best texture and flavor balance.
• 1 large egg plus 1 egg yolk, room temperature — the extra egg yolk adds richness and helps create a chewier, more tender cookie. Room temperature eggs incorporate more smoothly into the batter.
• 1 teaspoon vanilla extract
• 1 and 3/4 cups all-purpose flour — spoon the flour into your measuring cup and level it off rather than scooping directly — scooping compacts the flour and can lead to dry, cakey cookies.
• 1 teaspoon baking soda
• 1 teaspoon ground cinnamon — this is the secret ingredient that pushes the banana bread flavor over the edge. It adds warmth and depth that makes these taste unmistakably like banana bread in cookie form.
• 1/4 teaspoon ground nutmeg
• 1/2 teaspoon salt
• 1 and 1/2 cups semi-sweet chocolate chips — use good quality chocolate chips. Semi-sweet gives the best balance against the sweet banana dough but dark chocolate chips work beautifully too for a less sweet, more sophisticated flavor.
• Flaky sea salt for finishing — Maldon sea salt is the gold standard here. A small pinch on each cookie right before baking makes a genuinely noticeable difference to the final flavor. Do not skip this finishing touch.

Step-by-step instructions

Step 1: Brown the butter

Place the butter in a light-colored medium saucepan over medium heat. The light color of the pan helps you see when the butter is browning properly. Stir or swirl the pan frequently as the butter melts, foams, and then begins to turn golden. Keep cooking and stirring until the foam subsides and you see small golden-brown bits forming at the bottom of the pan and the butter smells deeply nutty and caramel-like — about 4-5 minutes total. Remove from heat immediately and pour into a large mixing bowl to stop the cooking. Let it cool for 10 minutes. Those golden-brown bits at the bottom are flavor gold — scrape every last one into the bowl. Ever had a cookie that tasted somehow deeper and more complex than a regular chocolate chip cookie and you could not figure out why? Nine times out of ten it was brown butter.

Step 2: Mix the wet ingredients

Once the brown butter has cooled slightly, add the brown sugar and granulated sugar to the bowl and whisk vigorously until well combined. Add the mashed banana and whisk again until smooth and fully incorporated. Add the egg, egg yolk, and vanilla extract and whisk until the mixture is smooth, glossy, and slightly thickened — about 60 seconds of vigorous whisking.

Step 3: Add the dry ingredients

Add the flour, baking soda, cinnamon, nutmeg, and salt to the bowl. Fold with a rubber spatula until just combined — stop as soon as no dry flour streaks remain. Do not overmix at this stage. Overmixing develops the gluten in the flour and results in tough, dense cookies instead of soft and chewy ones. A few folds of the spatula is all you need once the flour goes in.

Step 4: Fold in the chocolate chips

Add the chocolate chips and fold them in gently with the spatula until evenly distributed throughout the dough. Reserve a small handful of chips to press onto the tops of the cookies before baking — this is purely aesthetic but it makes the cookies look significantly more appealing when they come out of the oven.

Step 5: Chill the dough

Cover the bowl with plastic wrap and refrigerate the dough for at least 30 minutes. This step is important — chilling firms up the dough, prevents the cookies from spreading too thin during baking, and gives the flavors time to develop and deepen. If you have time, chilling for 1-2 hours or even overnight gives you an even better result. The banana flavor becomes more pronounced and the texture improves noticeably with a longer chill.

Step 6: Bake the cookies

Preheat the oven to 375°F / 190°C and line two baking sheets with parchment paper. Scoop the chilled dough into balls using a medium cookie scoop or two tablespoons — aim for about 2 tablespoons of dough per cookie. Place them on the prepared baking sheets with about 2 inches of space between each one. Press a few extra chocolate chips onto the top of each dough ball and sprinkle a small pinch of flaky sea salt on top of each one.

Step 7: Bake to perfection

Bake for 10-12 minutes until the edges are set and lightly golden but the centers still look slightly underdone and glossy. This is exactly right — the cookies will continue cooking on the hot baking sheet after you pull them from the oven and will firm up to perfect chewy consistency as they cool. Overbaked cookies lose that soft chewy center and become dry and crumbly — always err on the side of slightly underdone when it comes to cookies.

Step 8: Cool and serve

Let the cookies cool on the baking sheet for 5 minutes before transferring to a wire rack. They will be very soft when they first come out of the oven and need this time to set up properly. Serve warm for the best experience — warm cookies with melty chocolate and that banana bread aroma are genuinely hard to beat.

Serving suggestions

These cookies are pretty spectacular on their own but here are a few ways to enjoy them even more:

• Warm with a glass of cold milk — the absolute classic pairing that exists for a reason. A warm banana chocolate chip cookie with a cold glass of milk is one of the simplest and most satisfying combinations in all of baking.
• As an ice cream sandwich — sandwich two cookies around a scoop of vanilla or caramel ice cream for a dessert that feels genuinely special without much effort. The banana and chocolate flavors work beautifully with vanilla or salted caramel ice cream.
• With a drizzle of peanut butter — warm a couple tablespoons of smooth peanut butter and drizzle it over the cookies right before serving. Banana, chocolate, and peanut butter is a combination that has no bad days.
• Crumbled over yogurt or oatmeal — crumble a cookie or two over a bowl of Greek yogurt with fresh banana slices for a breakfast that feels like dessert but is arguably reasonable nutrition. Arguably.
• As a gift — stack six or eight cookies in a clear cellophane bag tied with a ribbon. These cookies are impressive enough to give as a gift and personal enough to feel genuinely thoughtful. FYI nobody has ever been unhappy to receive homemade cookies. That is just a fact.

Storage tips

Room temperature: Store completely cooled cookies in an airtight container at room temperature for up to 4 days. Place a piece of bread in the container alongside the cookies — the cookies will absorb moisture from the bread and stay soft and chewy for longer.

Refrigerator: These cookies keep well in the fridge in an airtight container for up to 1 week. Bring to room temperature before eating or warm briefly in the microwave for 10-15 seconds for that fresh-baked experience.

Freezer — baked cookies: Freeze completely cooled cookies in a single layer on a baking sheet until solid, then transfer to a freezer-safe zip-lock bag. Store for up to 2 months. Thaw at room temperature for about 30 minutes or warm in a 300°F oven for 5 minutes.

Freezer — cookie dough balls: Scoop the chilled dough into balls and freeze on a baking sheet until solid. Transfer to a freezer bag and store for up to 3 months. Bake directly from frozen — add 2-3 extra minutes to the baking time. Having frozen cookie dough ready to bake on demand is one of the best things you can do for your future self.

Note: Because these cookies contain banana, they are slightly more moist than a standard chocolate chip cookie and can become sticky if stored uncovered. Always store in a sealed airtight container.

Brief closing

One bowl, overripe bananas you were probably going to throw away anyway, and 30 minutes of chill time standing between you and some of the best cookies you have ever made.

These chewy banana bread chocolate chip cookies deliver on every level — flavor, texture, and that deeply satisfying combination of warm banana, melty chocolate, and flaky sea salt that makes it very hard to stop at just one.

Bake a batch this weekend, sprinkle on that sea salt generously, and eat at least two while they are still warm from the oven. You deserve it. Drop a comment below and let me know how yours turned out — and whether you managed to save any for the next day. :)
