Irresistible Brown Butter Banana Chocolate Chip Cookies: Your New Favorite Chewy Treat
Prepare to fall in love with these extraordinary Brown Butter Banana Chocolate Chip Cookies! Imagine a cookie that perfectly blends the comforting sweetness of ripe bananas with the rich, nutty depth of browned butter, all generously studded with melty chocolate chips. This recipe takes classic banana bread flavors and transforms them into a chewy, decadent cookie experience. They are soft, packed with flavor, and so simple to make, you’ll wonder why you haven’t been baking them all along. Whether you’re a seasoned baker or just starting, these cookies are guaranteed to become a household favorite, perfect for any occasion.

Why These Brown Butter Banana Chocolate Chip Cookies Stand Out
What makes these banana chocolate chip cookies truly special? It all comes down to a few key elements that elevate them far beyond your average cookie. First and foremost is the browned butter. This simple step, which involves gently cooking butter until the milk solids toast and turn a rich amber, infuses the entire dough with an incredible nutty, caramel-like aroma and flavor that’s utterly addictive. It adds a depth that plain melted butter simply cannot match, creating a more sophisticated and complex taste profile.
Next, we harness the power of overripe bananas. These aren’t just for banana bread anymore! A truly ripe banana, with its speckled skin, provides natural sweetness and an amazing moisture content, resulting in a supremely soft and chewy cookie. The subtle banana flavor complements the browned butter beautifully, creating a harmonious blend that’s both familiar and exciting. Combined with a classic mix of granulated and brown sugars, these cookies achieve that coveted crisp edge and delightfully soft center texture that cookie dreams are made of. And of course, we can’t forget the generous amount of chocolate chips, ensuring a burst of chocolatey goodness in every single bite. The blend of simple ingredients, when handled correctly, produces a cookie that is both comforting and gourmet.
Essential Ingredients for Your Perfect Brown Butter Banana Cookies
Crafting the perfect batch of these delightful cookies starts with understanding the role each ingredient plays. Here’s a detailed look at what you’ll need and why each component is crucial for achieving that amazing flavor and texture:
- Butter: You’ll need ½ cup of unsalted butter, which will be browned and then cooled. Browning the butter is a game-changer for this recipe. It toasts the milk solids, imparting a rich, nutty, and caramel-like flavor that elevates the entire cookie experience. Make sure to cool it slightly before incorporating it to avoid scrambling the egg or altering the sugar’s texture.
- Banana: One medium overripe banana, mashed (about ¼ cup), is vital. The riper the banana (look for plenty of brown spots!), the sweeter and more flavorful it will be. It provides natural moisture, allowing for a chewy cookie without adding excess liquid, and a subtle, comforting banana essence.
- Egg Yolk: Just 1 large egg yolk, at room temperature, is used instead of a whole egg. The yolk provides richness and helps bind the ingredients, contributing to a wonderfully chewy texture. Omitting the egg white helps prevent the cookies from becoming too cake-like, ensuring that classic gooey-chewy center we all love.
- Vanilla Extract: 1 teaspoon of pure vanilla extract is essential for enhancing all the incredible flavors. Its warm, aromatic notes complement both the browned butter and the banana, adding a layer of depth to the cookie’s overall profile.
- Sugars: A combination of ⅓ cup granulated sugar and ½ cup packed light brown sugar is key. Granulated sugar provides structure and contributes to the crisp edges, while light brown sugar adds moisture, chewiness, and a subtle molasses flavor that pairs perfectly with the browned butter and banana.
- Flour: You’ll need 1 ⅓ cups of all-purpose flour. This forms the primary structure of your cookie dough. Ensure you measure it correctly, preferably by weighing it or using the spoon-and-level method, to prevent overly dense or dry cookies.
- Baking Soda: ½ teaspoon of baking soda acts as the leavening agent. When combined with the acidic elements (like brown sugar and banana), it helps the cookies rise and spread, resulting in a soft, airy texture in the center while maintaining chewiness.
- Ground Cinnamon: ½ teaspoon of ground cinnamon adds a touch of warmth and spice. It beautifully enhances the banana flavor and complements the nutty notes from the browned butter, making each bite even more inviting.
- Salt: ¼ teaspoon of fine sea salt is crucial for balancing the sweetness of the cookies. It also helps to highlight the other flavors, making them pop. Don’t skip this, as it prevents the cookies from tasting one-dimensional.
- Chocolate Chips: You will need ⅔ cup of your favorite chocolate chips, plus a little extra for topping if desired. Whether you choose milk, semi-sweet, dark, or even a mix of chunks and chips, the chocolate provides delightful pockets of melty goodness throughout the cookie.
- Optional: Flaky Sea Salt: A sprinkle of flaky sea salt on top of the baked cookies is highly recommended. It provides a beautiful aesthetic and a delightful contrast in flavor and texture, enhancing the sweetness and the overall gourmet feel.

Expert Tips for Baking the Best Banana Chocolate Chip Cookies
Achieving cookie perfection is easier than you think with these valuable tips. Follow these suggestions to ensure your Brown Butter Banana Chocolate Chip Cookies turn out flawlessly every time:
- Banana Selection and Preparation: For truly exceptional flavor and moisture, always opt for overripe bananas. These are bananas with skins that are heavily speckled brown or even mostly brown. The starches convert to sugars as bananas ripen, making them much sweeter and softer. If you have ripe bananas but aren’t ready to bake, simply peel them and freeze them in an airtight container or bag. When you’re ready to use them, thaw them overnight in the refrigerator. The thawed bananas might look a little discolored and watery, but they are perfectly fine for baking. Just squeeze out any excess liquid, mash them well (you’ll need exactly ¼ cup for this recipe), and let them come to room temperature before adding them to your dough. This step is crucial for consistent cookie texture.
- Customizing Your Chocolate Chips: While semi-sweet chocolate chips are a classic choice, don’t hesitate to experiment with different types of chocolate to suit your preference. For an extra rich flavor, try dark chocolate chunks or chips. If you prefer a sweeter cookie, milk chocolate works wonderfully. A half-and-half mixture of dark and semi-sweet, or even milk and semi-sweet, can create a complex flavor profile. You can also elevate these cookies by adding other mix-ins, such as chopped pecans or walnuts, for a delightful textural contrast and nutty flavor boost. Ensure any nuts are lightly toasted before adding them to enhance their aroma.
- The Magic of Using Only an Egg Yolk: This recipe specifically calls for just an egg yolk, and for a good reason! Egg whites contain a lot of water and protein, which can contribute to a lighter, more cake-like texture in cookies. By using only the egg yolk, we introduce more fat and richness to the dough, leading to a denser, chewier, and wonderfully moist cookie. The fat in the yolk also emulsifies with the browned butter, creating a supremely tender crumb. Using room temperature ingredients, including the egg yolk, ensures that everything mixes together smoothly and uniformly, preventing lumps and creating a consistent dough.
- Don’t Skip the Brown Butter Cooling Step: After browning your butter, it’s vital to let it cool down to at least lukewarm, or preferably room temperature, before mixing it with the sugars and other wet ingredients. Adding hot butter to the sugars can melt them too quickly, leading to greasy cookies. More importantly, adding hot butter to an egg yolk can partially cook the egg, resulting in an undesirable texture and flavor. Patience here pays off for that perfect chew and spread.
- Avoid Overmixing the Dough: Once you add the dry ingredients to the wet, mix just until no streaks of flour remain. Overmixing develops the gluten in the flour, which can lead to tough, dry cookies. A light hand will ensure your cookies remain tender and chewy. Fold in the chocolate chips gently at the very end.
- The Importance of Resting (Optional but Recommended): While not strictly required, letting your cookie dough chill in the refrigerator for at least 30 minutes (or even overnight) can significantly improve the flavor and texture. Chilling allows the flour to fully hydrate, the flavors to meld, and the fat to firm up. This results in less spreading, thicker cookies, and a more developed, intense flavor profile. If you have the time, give it a try!

Storing and Freezing Brown Butter Banana Chocolate Chip Cookies
Once your irresistible cookies are baked and cooled, proper storage is key to maintaining their deliciousness. For short-term enjoyment, store your completely cooled cookies in an airtight container at room temperature. They will stay wonderfully fresh and soft for up to 3-4 days. If you prefer, you can also store them in the refrigerator for up to 5 days, though their texture might become slightly firmer.
A classic trick to keep cookies extra soft is to add a slice of plain white bread to the container. The cookies will absorb moisture from the bread, helping them retain their chewiness and preventing them from drying out. Just remember to replace the bread slice every couple of days.
For longer storage, these cookies freeze beautifully. First, arrange the cooled cookies in a single layer on a baking sheet and freeze them until they are firm (this prevents them from sticking together). Once frozen, transfer them to a heavy-duty freezer bag or an airtight freezer-safe container. They will keep well in the freezer for up to 3 months. When you’re ready to enjoy them, simply leave the cookies at room temperature for about an hour to thaw. For a truly ‘fresh from the oven’ experience, you can warm them briefly in the microwave (10-15 seconds) or in a preheated oven (3-5 minutes at 275°F/135°C). Reheating not only softens them but also re-awakens the incredible flavors of the browned butter and chocolate, making them taste as good as the day they were baked.

Banana Chocolate Chip Cookies Recipe

Rate
Ingredients
- ½ cup butter browned and cooled
- 1 medium overripe banana mashed (¼ cup)
- 1 egg yolk room temperature
- 1 tsp vanilla extract
- ⅓ cup granulated sugar
- ½ cup packed light brown sugar
- 1 ⅓ cup all-purpose flour
- ½ tsp baking soda
- ½ tsp ground cinnamon
- ¼ tsp salt
- ⅔ cup chocolate chips optional: plus a little extra for topping
- Optional: Flaky sea salt for topping
Instructions
-
Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper to prevent sticking and ensure even baking, then set it aside.
-
To brown the butter: Place ½ cup of butter in a light-colored saucepan or small pot over medium-low heat. Stir constantly to ensure the butter melts evenly and doesn’t burn. Initially, it will melt, then foam, and finally, small golden-brown bits will appear at the bottom. Continue stirring until the butter smells wonderfully nutty and turns a golden amber color. This usually takes about 5-10 minutes. Immediately remove the saucepan from the heat and pour the browned butter into a separate heat-proof dish to cool. Allow it to cool for 10-15 minutes, until it reaches a lukewarm or room temperature state. This cooling step is crucial.
-
While the browned butter is cooling, prepare your overripe banana. Mash it thoroughly with a fork until smooth, then measure out exactly ¼ cup. Ensure it’s at room temperature before proceeding.
-
In a separate medium-sized mixing bowl, whisk together the all-purpose flour, baking soda, ground cinnamon, and salt. Make sure these dry ingredients are thoroughly blended to ensure even distribution in the dough.
-
In a large mixing bowl, add both the granulated sugar and the packed light brown sugar to the cooled browned butter. Whisk them together vigorously until they are well combined and the mixture is light and fluffy. Next, add the mashed banana, the room temperature egg yolk, and the vanilla extract. Whisk again until the mixture is smooth and all wet ingredients are fully incorporated.
-
Gradually add the dry flour mixture into the wet mixture, stirring gently with a spatula or wooden spoon until just combined. Be careful not to overmix the dough, as this can lead to tough cookies. Once the flour is mostly incorporated, fold in the chocolate chips until they are evenly distributed throughout the dough.
-
Using a medium cookie scoop (a #40 scoop, equivalent to about 1.5 tablespoons, works perfectly), scoop rounded balls of dough onto the prepared baking sheets. Arrange them about 3 inches apart to allow for proper spreading during baking.
-
For an extra visual appeal and chocolatey punch, gently press a few extra chocolate chips onto the top of each cookie dough ball before baking. Bake the cookies in your pre-heated oven for approximately 10-12 minutes. Look for edges that are golden brown and centers that still appear slightly underbaked and soft.
-
Once baked, remove the cookies from the oven. Allow them to cool on the baking sheets for at least 10 minutes. This critical cooling time allows them to firm up and set, preventing breakage when you transfer them. After 10 minutes, carefully move the cookies to a wire rack to cool completely. If desired, sprinkle them with a touch of flaky sea salt while they are still warm. Serve warm or at room temperature, and enjoy these utterly delicious treats!
Notes
For extended storage, flash-freeze cookies in a single layer on a sheet pan until firm, then transfer them to a freezer bag or an airtight container. These can be frozen for up to 3 months without losing quality.

Frequently Asked Questions About Banana Chocolate Chip Cookies
What can I substitute for an egg yolk in these banana cookies?
If you need an egg yolk substitute for these banana chocolate chip cookies, there are a few options, though each may slightly alter the final texture or flavor. A popular choice is using 2 tablespoons of unsweetened applesauce or mashed avocado. These alternatives provide moisture and some binding properties, making them suitable for vegan or egg-allergy diets. Another effective substitute is a flaxseed egg: simply combine 1 tablespoon of ground flaxseeds with 3 tablespoons of water, stir well, and let it sit for about 5 minutes until it thickens to a gel-like consistency. This creates a good binder. While these substitutes can work, remember that the egg yolk’s specific fat content contributes significantly to the cookie’s signature chewy, rich texture, which might be slightly different with alternatives.
Is it necessary to use overripe bananas for baking these cookies?
Absolutely, yes! Using overripe bananas is not just recommended, it’s essential for the best possible outcome for these cookies. As bananas ripen, their starches convert into natural sugars, making them significantly sweeter. This natural sweetness reduces the need for excessive added sugar and enhances the overall banana flavor in your cookies. More importantly, overripe bananas are much softer and contain more moisture, which is key to achieving that wonderfully moist and chewy texture. Bananas with mostly brown or heavily speckled skins are ideal; the softer the banana, the sweeter and moister your cookies will be. Avoid underripe or just-ripe bananas, as they lack sufficient sugar and moisture, which can result in dry, less flavorful cookies that might not spread as desired. Always measure your mashed banana carefully—¼ cup is the perfect amount to provide moisture without making the dough too wet.
How can you tell when the banana cookies are done baking?
Knowing when your banana cookies are perfectly baked is crucial for achieving that ideal balance of soft and chewy. The cookies are typically done when their edges turn a light golden brown, but their centers still look slightly underbaked, soft, and puffy. They might even appear a bit gooey in the middle. This slight underbaking is what gives them that desirable chewy texture once they’ve cooled. Overbaking will result in drier, crispier cookies. Once removed from the oven, allow the cookies to cool on the baking sheet for at least 10 minutes. During this time, they will continue to cook slightly from residual heat, firm up, and set their chewy texture, preventing them from breaking when you transfer them to a wire rack for complete cooling.
My cookies spread too much. What went wrong?
Several factors can cause cookies to spread too much. Ensure your browned butter was properly cooled to lukewarm or room temperature, not still warm, as warm butter can cause excessive spreading. Also, make sure your mashed banana is exactly ¼ cup; too much banana adds excess moisture. Using too much baking soda or not enough flour can also be culprits. For best results, measure your flour by weight (1 ⅓ cups is approximately 160g) or use the spoon-and-level method to avoid packing it too densely. Chilling the dough for at least 30 minutes before baking can also significantly help prevent spreading by firming up the butter in the dough.
