Made from marbled layers of brownie batter and chocolate chip cookie dough, brookies are a fun treat for all ages.
Is it a brownie? Is it a cookie? Nope, it’s a brookie! Brookies are bars made from marbled layers of fudgy brownie batter and cakey chocolate chip cookie dough. When I first heard of them, I thought they were a silly fad (why mess with the classics?) but then I tried them and, boy, was I wrong. Brookies are not only super delicious, but they’re also more festive than your basic brownie recipe or chocolate chip cookies. They’re perfect for those occasions when you need a fun potluck treat for all ages — and they’re pretty handy for packing in lunch boxes and late-night snacking, too.

What You’ll Need To Make Brookies
You’ll need two types of chocolate for this recipe: semi-sweet chocolate chips for the cookie layer and bittersweet chocolate for the brownie layer. The label on the bittersweet chocolate I use for this recipe indicates that it contains 60% cacao. Don’t get too caught up in the percentages though, because there are no legal regulations that indicate exactly how much cacao bittersweet chocolate must have. Instead, just make sure what you purchase is labeled bittersweet.
Step-by-Step Instructions
Step 1: Make the Brownie Batter
To begin, place the butter in a medium microwave-safe bowl and melt in the microwave until bubbling. Add the chocolate and whisk until the chocolate is completely melted.
The heat from the butter should be enough to melt the chocolate completely, but if not, place the chocolate-butter mixture in the microwave and heat for 20 seconds or so, then whisk again.
Whisk in the granulated sugar, brown sugar, vanilla, and salt. The mixture will be a bit grainy; that’s okay.
Whisk in the eggs.
Finally, whisk in the flour until combined.
Pour the batter into the prepared pan and spread evenly with a spatula. Set aside.
Step 2: Make the Cookie Dough
Put the butter and both sugars in the bowl of an electric mixer (or a medium bowl if you’re using a hand mixer). Beat for 3 minutes, or until light and fluffy.
Add the vanilla and egg and beat for 1 minute more.
Add the salt, baking powder, and baking soda and beat briefly until evenly combined.
On low speed, mix in the flour.
Add the chocolate chips and mix briefly to combine.
Step 3: Assemble and Bake
Dollop small spoonfuls of the cookie dough evenly over the brownie batter (no need to spread it out or press it down).
Cover the pan with aluminum foil and bake for 20 minutes. Remove the foil and continue baking until the brownie edges are shiny and the cookie portion is golden brown, about 20 minutes more.
Transfer the pan to a wire rack and cool completely. To cut, lift the brookies out of the pan using the parchment overhang and transfer them to a cutting board. Pull the parchment away from the edges and, using a sharp knife, cut the brookies into 2-inch squares.
Store the brookies in an airtight container on the countertop for up to three days or freeze for longer storage. Enjoy!

Ingredients
For the Brownie Batter
- 1 stick (½ cup) unsalted butter
- 4 oz bittersweet chocolate, roughly chopped (best quality, such as Ghirardelli)
- ½ cup granulated sugar
- ½ cup packed light brown sugar
- 1 teaspoon vanilla extract
- ¼ teaspoon salt
- 2 large eggs
- ½ cup all-purpose flour, spooned into measuring cup and leveled off with knife
For the Cookie Dough
- 1 stick (½ cup) unsalted butter, at room temperature
- ⅓ cup granulated sugar
- ⅓ cup packed light brown sugar
- ½ teaspoon vanilla extract
- 1 large egg
- ½ teaspoon salt
- ½ teaspoon baking powder
- ¼ teaspoon baking soda
- 1¼ cups all-purpose flour, spooned into measuring cup and leveled-off with a knife
- ½ cup semi-sweet chocolate chips
Instructions
- Set the rack in the middle of the oven and preheat to 350°F. Line a 13 x 9 x 2-inch pan with parchment paper (bring the parchment up the sides of pan so there is a slight overhang) and grease with butter or nonstick cooking spray. (If the parchment is slipping, dot a little butter or nonstick spray in the corners of the pan to help the parchment stick.)
- Make the brownie batter: Place the butter in a medium microwave-safe bowl and melt in the microwave until bubbling. Add the chocolate and whisk until the chocolate is completely melted. The heat from the butter should be enough to melt the chocolate completely, but if not, place the chocolate-butter mixture in the microwave and heat for 20 seconds or so, then whisk again. (Alternatively, combine the butter and chocolate in a heatproof bowl and set over a pan of simmering water. Stir occasionally until melted.) Whisk in the granulated sugar, brown sugar, vanilla, and salt. The mixture will be a bit grainy; that's okay. Whisk in the eggs. Finally, whisk in the flour until combined. Pour the batter into the prepared pan and spread evenly with a spatula. Set aside.
- Make the cookie dough: In the bowl of an electric mixer fitted with the paddle or beaters, beat the butter and both sugars for 3 minutes, or until light and fluffy. Scrape down the sides and bottom of the bowl as necessary. Add the vanilla and egg and beat for 1 minute more. Scrape down the sides of the bowl again. Add the salt, baking powder, and baking soda and beat briefly until evenly combined. On low speed, mix in the flour. Finally, add the chocolate chips and mix until just combined.
- Dollop small spoonfuls of the cookie dough evenly over the brownie batter (no need to spread it out or press it down). Cover the pan with aluminum foil and bake for 20 minutes. Remove the foil and continue baking until the brownie edges are shiny and the cookie portion is golden brown, about 20 minutes more. Transfer the pan to a wire rack and cool completely. To cut, lift the brookies out of the pan using the parchment overhang and transfer them to a cutting board. Pull the parchment away from the edges. Using a sharp knife, cut the brookies into 2-in squares directly on the parchment.
- Make-Ahead/Freezer-Friendly Instructions: Brookies can be stored in an airtight container at room temperature for up to 3 days; freeze for longer storage.

I don’t know how anyone would rate these as anything lower than 5 stars. This is our go to recipe when we can’t decide between a brownie or a cookie (often). We receive glowing reviews when we make these for events.
Too sweet I would cut down on the sugar next time and cookie part was too dry. I followed the recipe word for word.
This recipe is amazing, life changing amazing. We are so excited to make them again.
Made exactly as written. Our kids LOVED them! No need to change anything, but I might try sprinkling some mini chocolate chips (or regular) over the top when the top is set enough to not let the chips sink down.
They were soft and chewy and turned out perfect.
Way too complicated, time-consuming, and requiring so much equipment to make.
I followed the recipe exactly and the result was a dry, hard product. I won’t spend valuable time doing this again. Store bought brownie mix would have been moister and more tasty.
Made them twice to rave reviews. I used a nonstick Edge Brownie Pan, sprayed with Pam. I used Ghiardelli bittersweet morsels instead of the bar – not sure if it makes a difference, but will look for the bar next time I am shopping.
I want to make brookiecicles….do you think these are sturdy enough to stay on a stick??
Unfortunately, I don’t think they would be — sorry!
Love YOUR Brookie Recipe! Made the one from the person who invented them first, then yours. Yours is the winner hands down!!!!!
My grandkids agree!!!
Hi Jenn!
