These semi-homemade Brownie Cookie Swirls combine classic chocolate chip dough with rich, fudgy brownie batter in one delicious treat! They are soft, chewy, full of chocolatey goodness, and surprisingly easy to make with just a handful of ingredients. So, whether you crave a chocolate chip cookie or a brownie, why not satisfy both in one bite with these cookie swirls? If you love the combination of cookie dough and brownie flavors in these swirls, you will definitely want to try my Cookie Dough Brownie Ice Cream, too!

What Are Brownie Cookie Swirls?
Brownie cookie swirls (or easy ‘brookies’) are a fun, tasty treat that became popular on TikTok. Theyโre made by rolling thick, fudgy brownie batter over cookie dough, then slicing and baking the dough into delicious swirled cookies with both brownie and cookie flavors in every bite. If you are looking for an easy dessert to bake with kids, this is it! It’s fun to roll, simple to slice, and so yummy to eat!
Ingredients & Substitutions
- Chocolate Chip Cookie Dough: Look for a 16.5-ounce package of refrigerated chocolate chip cookie dough. It doesn’t get much easier than that!
- Brownie Mix: I have a homemade brownie mix that makes the best brownies, and would also work for this recipe. Or, look for a 16.3-ounce box mix. Important: Do not follow the box instructions; instead, use the oil, egg, and water amounts listed in this recipe. After mixing the brownie batter, you will only use about 3/4 cup of the batter to spread over the cookie dough.

What Can I Do With The Leftover Brownie Batter?
Since youโll only need ยพ cup of the brownie batter for the swirls, you can bake the rest as mini brownies in a muffin tin or small pan. Just adjust the baking time based on the pan size. (I would start checking around 12โ15 minutes.) Use the ‘bonus brownies’ in another recipe like my Peanut Butter Brownie Trifle or Ultimate Chocolate Milkshake with Brownie! You can also freeze the extra batter for later or make a second batch of swirls.
Can I Use Homemade Chocolate Chip Cookie Dough?
Yes! Homemade chocolate chip cookie dough works great for brownie cookie swirls. Just chill the dough first so itโs firm enough to roll out easily. This way, you can enjoy a fresh, homemade flavor in every bite.

Can I Make Brownie Cookie Swirls Ahead of Time?
Yes! You can prepare the rolled brownie cookie dough log ahead by wrapping it tightly in plastic wrap and refrigerating for up to 2 days or freezing for up to 1 month. When ready, slice and bake as usual, adding a few extra minutes to the baking time if frozen.
Can I Customize These Cookies?
Yes! You can add mini chocolate chips, nuts, or candy to the brownie batter. Or try spreading Nutella, peanut butter, or caramel sauce instead of brownie mix for a fun twist. These are easy to make your own, especially with kids!

How To Store Brownie Cookie Swirls
Store cooled cookie swirls in an airtight container at room temperature for up to 3 days. For longer freshness, you can keep them in the refrigerator for up to a week.
Can I Freeze These Brownie Swirl Cookies?
Yes! To freeze baked swirls, place them in a single layer on a baking sheet and freeze until firm. Then transfer to a freezer-safe bag or container and freeze for up to 3 months. Thaw at room temperature before enjoying.
