These Chewy Banana Chocolate Chip Cookies have a golden edge, a chewy center, and a perfect balance of sweetness from the banana and milk chocolate chips. They’re a delicious twist on the classic chocolate chip cookie we all know and love!

Ingredients & Substitutions
- Butter: Melting the butter before mixing it with the other ingredients helps make these cookies crispy. Normally, cookies use softened butter, but melting it helps the dough spread more as it bakes, giving the cookies that crispy edge while still keeping the center chewy. I prefer unsalted butter, but salted butter works, too, you just may want to lessen the amount of salt.
- Sugar: I used both granulated sugar and brown sugar in these cookies. Using both helps make the cookies taste just right. Granulated sugar makes them crispy, while brown sugar adds moisture and extra flavor. If you use just one, they will still taste good, but the texture might be different. If you want chewier cookies, you can use all brown sugar, or all granulated sugar for a crispier bite. Either way, they will be a little different from the original recipe!
- Banana: For a banana flavor in each bite, mash one ripe banana. Overripe bananas work great because they are sweeter and mash more easily in the dough.
- Cornstarch: For these crispy cookies, I wanted the outside crispy, but still keep the center chewy. That is where cornstarch comes in. If you leave it out, the cookies might spread too much and not be as soft in the middle.
- Chocolate Chips: I used milk chocolate chips because they add a smooth, creamy sweetness that goes really well with the banana. But if you like a richer, less sweet flavor, you can definitely use semi-sweet chocolate instead! I think dark chocolate chips would be delicious, too.

Do Banana Chocolate Chip Cookies Have Eggs?
Nope, I didn’t forget the eggs! This recipe doesn’t use eggs because the mashed banana helps bind the ingredients and adds moisture, just like eggs would. The banana also adds extra flavor and texture, making the cookies soft in the center and crispy on the outside without needing eggs. I talk all about how bananas can be an egg substitute ⬅️ here!
How To Freeze Cookie Dough For Later
I love freshly baked cookies, and to enjoy one (or the whole batch!) whenever the craving hits, freeze the dough for later! To freeze, scoop the dough with an ice cream scoop and place the dough balls close together on a lined baking sheet. Freeze for about 30 minutes, or until they’re very cold. Then transfer the dough balls into a freezer-safe plastic bag or airtight container. When you’re ready to bake, thaw the dough overnight, or bake them straight from frozen—just add 3-5 extra minutes to the baking time!

How To Store Chewy Banana Chocolate Chip Cookies
To keep these banana chocolate chip cookies fresh, store them in an airtight container at room temperature for up to 5 days. For longer storage, freeze the cookies.
Can I Freeze Baked Cookies?
Absolutely! To freeze baked cookies, place them on a cookie sheet and freeze for 30 minutes. Then, transfer them to an airtight container or a freezer bag with the air removed. Freeze for up to 3 months! For more tips, check out my Guide to Freezing, Baking, and Storing Cookies.
