What could be better than combining two of our FAVORITE treats?! Brookies is a mash-up of brownies and chocolate chip cookies all in one deliciously decadent bite.
We may be obsessed. It doesn’t help that they are SO easy to whip up! Simply prepare a brownie batter and spread it in a pan. Now mix up cookie dough batter, add dollops to the brownie layer, and bake! This is one next-level dessert you are going to love!
The kids like to serve it up with a scoop of vanilla ice cream to guarantee a sugar coma – you can’t go wrong!
Why we think you’ll love it:
- Two desserts in one. It doesn’t get much better than combining brownies and cookies for one decadent, easy dessert!
- A simple show-stopper. We used two simple batters to create one eye-popping delight.
- Easy to double. This whips up around 16 servings (you don’t need much when it’s this rich), but can easily to be doubled to serve even more!

How to Make Brookies
- PREP. Preheat the oven to 325°F. Line an 8×8 or 9×9 square pan or baking dish with parchment paper.
- COOKIE LAYER. In a medium bowl or the bowl of a stand mixer, mix the butter, brown sugar, and sugar. Add the egg and vanilla, and mix until combined.
- Add the flour, baking soda, and salt, and mix to form a soft chocolate chip cookie dough. Gently fold in the chocolate chips. Refrigerate until ready to use.
- BROWNIE LAYER. In a large bowl, whisk the butter and sugar. Add the eggs and vanilla, and mix until smooth. Add the flour, cocoa powder, baking soda, and salt, and mix until just combined. Fold in the chocolate chips.
- BAKE. Spread the brownie mixture in the prepared pan. Scoop large scoops of the cookie dough onto the top of the brownie batter, then sprinkle with the flaky sea salt.
- Bake 40-50 minutes, or until a toothpick inserted 1½ inches from the side of the pan comes out clean or with a few moist crumbs. Let the brownies cool completely before slicing and serving.
Kristyn’s Recipe Tips
- This is a delicious recipe to make gluten-free, just substitute the all-purpose flour with a 1:1 gluten-free baking flour.
- Don’t fully cover with dough; we like to see some of the brownie batter to peek through the cookie dough.
- Baking times can vary depending on your oven and the pan used. Start checking for doneness around 40 minutes.
- Allow the brookies to cool completely in the pan before slicing. This allows them to firm up and makes them easier to cut cleanly.
- Don’t skip the flaky sea salt! It’s our secret ingredient and provides a wonderful contrast to the sweetness of the brookies.

Recipe FAQ
Metal pans conduct heat more evenly than glass pans, which can affect baking time. If using a glass pan, you might need to reduce the oven temperature by 25°F and bake slightly longer.
You can prepare the cookie dough and brownie batter 1-2 days ahead and keep them stored in the refrigerator in separate airtight containers. Let them sit at room temperature for about 20 minutes before assembling and baking.
Store leftover brookies in an airtight container at room temperature for up to 3-4 days or in the refrigerator for 5-7 days.
To freeze, wrap each brookie in plastic and store them together in a freezer-safe container for up to 3 months.
