Is it a brownie? Is it a cookie? Nope, it’s a brookie! These bars combine marbled layers of fudgy brownie batter and chewy chocolate chip cookie dough. When I first heard of them, I assumed they were just a silly fad (why mess with the classics?), but one bite changed my mind.

Not only are brookies incredibly delicious, but they’re also a step up from your basic brownie recipe or chocolate chip cookies—perfect for when you need a fun, crowd-pleasing treat for all ages.

The ultimate mash-up of brownies and cookies, these brookies are rich, fudgy, and chewy—perfect for when you can’t decide between two favorite treats!
Servings: 24 brookies
Prep Time: 20 minutes
Cook Time: 35 minutes
Total Time: 1 hour

Ingredients 

For the Brownie Batter

  • ½ cup (1 stick) unsalted butter
  • 4 oz bittersweet chocolate, roughly chopped
  • 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

For the Cookie Dough

  • ½ cup (1 stick) unsalted butter, softened
  • cup granulated sugar
  • cup (packed) light brown sugar
  • ½ teaspoon vanilla extract
  • 1 large egg
  • ½ teaspoon salt
  • ½ teaspoon baking powder
  • ¼ teaspoon baking soda
  • cups all-purpose flour, spooned into measuring cup and leveled-off
  • ½ cup semi-sweet chocolate chips

Instructions

  • Set the rack in the middle of the oven and preheat to 350°F (175°C). Line a 13 x 9 x 2-inch (33 x 22 x 5-cm) 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-inch (5-cm) squares directly on the parchment.

Notes

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.

  • 3 stars
    Too sweet I would cut down on the sugar next time and cookie part was too dry. I followed the recipe word for word.

  • 5 stars

    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.

  • 5 stars
    They were soft and chewy and turned out perfect.

  • 2 stars
    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!

    My grandkids agree!!!
