Is it a brownie or is it a cookie? These Brookies are a chocolate chip cookie/brownie hybrid. With patches of fudgy chocolate brownie and chewy chocolate chip cookies, these Brookie Bars are the best of both worlds.
Brookies: The Best of Both Worlds
Today we’re teaming up Chocolate Chip Cookies with my favorite Brownie Recipe to make Brookies. These two worlds collide to make a decadent treat that’s the perfect marriage of cookie and brownie. Can you think of a better way to kick off the weekend?
Served brownie-style (/in a pan), this recipe has swirls of fudgy, chocolatey brownie and chewy chocolate chip cookies.
Brookies are easy to make; you don’t need a mixer for either the brownie batter or the cookie dough. There’s no chilling required, and everything can be baked in just one pan (perfect if you don’t feel like scooping a ton of cookie dough). However, I still don’t feel right calling them a “lazy day recipe” (like my Oatmeal Cookie Bars).
We’re still effectively making two different batters, and so that means twice the dishes than if you were just making brownies or cookie bars. Fortunately the brownies can be made in just one bowl but you’ll still have three bowls to wash when all is said and done. Just a fair warning for anyone else who hates doing dishes as much as I do.
Fortunately the reward for all this dishwashing is pretty great…
How to Make Brookies (From Scratch!)
- Start by making the cookie dough. Combine melted (cooled) butter, sugars, eggs, and vanilla and stir well. Combine the dry ingredients separately and then stir the wet and dry ingredients together to make your cookie dough. Don’t forget to stir in chocolate chips!
- Next, make your brownie batter. Melt together chocolate chips and butter, then stir in cocoa powder. Add sugars, eggs, vanilla extract, and salt and stir well. Finally stir in your flower.
- Assemble. Lightly grease a 9×13 baking dish and alternate dropping large spoonfuls of brownie batter and cookie dough into the pan. I like to use ice cream scoops or large cookie dough scoops, but just try to make the dollops about the same size. Use a knife to swirl the cookie dough and brownie batter together. Make sure the dough is evenly distributed over the pan and there are no patches where dough is missing. Top everything off with additional chocolate chips, if you’d like!
- Bake. It’s very important that you don’t over-bake your Brookies or they’ll end up dry and crumbly. Use the toothpick test to check that they are done, but make sure you’re not accidentally sticking the toothpick in a chocolate chip. Do a few tests around the center. If the toothpick comes out clean, the Brookies are definitely done baking, but preferably you’ll catch them a few minutes before the clean toothpick stage. Ideally you want the toothpick to come back with a few fudgy/moist crumbs (not batter), this means they are finished and not over-baked, and they’ll be soft and chewy when cooled completely.
Anyone else want to top a warm Brookie slice with ice cream or is that just me?
Enjoy!

I absolutely LOVE your food blog, along with the videos. Thank you so much for sharing these recipes!
I do have a question as far as this Brookie recipe, do you use unsweetened or sweetened cocoa powder? Do you recommend a particular brand? I want to make these for Easter 🙂
Sam says
Thank you so much for the kind comment, Britt! I always use unsweetened cocoa powder, I like Ghirardelli, Nestle, and Hershey brands. I hope that helps! 🙂

In England we don’t use cornstarch, what is the next best thing to use.
Sam says
Hi Eileen! Look for corn flour, if you can’t find it leave it out. The cornstarch here helps make them a little more soft. 🙂

I make these for every birthday party we have since I found the recipe. They are AMAZING!!! Add a scoop of vanilla ice-cream to the top and OMG…you won’t regret it
Sam says
Oooo yeah ice cream on top is a great idea! 🙂
Kathleen says
Love Brookies. Truthfully, I have been making them for absolute years. In fact, I nick-named them Brookies because it was the nickname of my son-in-law’s boss.
Sam says
😂 They are quite an awesome treat! 🙂
