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!

Made from marbled layers of brownie batter and chocolate chip cookie dough, brookies are a fun treat for all ages.
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 am a brookie lover. Can I double this recipe and bake in a 9 x 13 p[an
I’m concerned that if you doubled the recipe, it wouldn’t all fit in a 9 x 13-inch baking dish. If you’d like them thicker, I’d stick to 1.5 times the recipe.
Have been making them for years, can’t believe I never reviewed them. So good…… Even a couple of snooty cooks who never ask for recipes asked for this one Jenn, if I wanted a larger size bar, could I do one and a half of the recipe in the 9 x 13 pan? thanks
So glad you’ve enjoyed them! Yes, I think you can get away with making 1.5 times the recipe and using the 9 x 13. The bake time will be a bit longer, but I’m not sure by how much, so keep a close eye on them. 😊
These are absolutely amazing!! I can’t stop eating them!! Thank you for a wonderful recipe.
I used a smaller pan, 1.5qt pyrex casserole, because I like thicker brownies. Worked great except I had to re-cover with foil and continue baking for about 8min but I expected that because I changed the pan size. I also used “allveg” butter flavored shortening in the cookie part. Otherwise I followed the recipe exactly. I may try them in a 13×9 but I worry they will be very thin
Someone is using your photo as their product image for their bakery.
Thanks for the heads up Stephanie!
Cooking these for 40 minutes was way too long. I’m not overly impressed with the entire recipe.
Loved the concept and was fun to make, but wasn’t impressed with the cookie part of the “Brookie” was too cakey.
Amazing recipe! I made these dairy free and gluten free using margarine, and gluten free flour. They were delicious! When you can make a recipe both dairy free and gluten free at the same time, you know it’s delicious! The brownie was super soft and a perfect texture. The cookie was a little crumbly, but still tasted great and could be the gluten free flour.
We love these and find they are not overly sweet which is nice. I burnt them on the bottom the first time and now bake for 20 minutes covered and then 10 minutes uncovered (in metal 9×13) and they turn out perfectly!
So amazing!
Made these today and the flavors are very nice together. The brownie part was bit too soft for us and the cookie was just right. I did end up pulling them out @ 17 minutes because they were getting too brown.
I’d like to try and par-bake the brownie before adding the cookie dough… do you think that would address the issue of a too gooey bottom? Or should I bake covered in foil longer? Or perhaps bake the brownie covered in foil for 5-7 minute and then top w/ cookie dough?
Your expert advice would be appreciated. 😊
Hi Lori, sorry that the texture of the brownie portion was not quite right!. Next time I’d add a few more tablespoons of flour to the brownie batter. And if you want to cover it with foil while baking, I’d cook it halfway and then cover it with foil for the remainder of the baking time if you see it’s getting browned. Hope that helps!
Could you make a big batch by doubling the recipe?
Sure!
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!
These are absolutely amazing!! I have made them many times and everyone always loves them! I use Trader Joe’s Pound Plus 72% Dark Chocolate in the brownies and they are absolutely incredible every time! 10/10 would recommend
This is a fabulous bar cookie! I have made it at least a dozen times. I bring brookies to my dentist’s office nearly every visit – they usually ask for them when I get my reminder phone call. My daughter scooped up the recipe after her first taste. The recipe is foolproof. The bars are moist and just the right mix of flavors. I made them the first time because I was intrigued. I really didn’t think the flavors of a brownie and a chocolate chip cookie would go together, but I was wrong. Try them – easy, make a good quantity, plenty of compliments.
I’m pretty sure there are multiple reviews from my family on this recipe, it’s that good! I made it first and shared it, and now it’s become a dessert staple.
I made these for a holiday party. They were a huge hit. Will definitely make these again. I may make in a smaller pan so they are thicker and adjust my cooking time and see how it goes.
This is one of my most requested desserts! So much quicker to make than multiple pans of cookies and equally delicious. My brother-in-law told me they are better than the brookies at his local coffee shop/bakery that sell for $3 a bar!
I almost didn’t make these as I wasn’t sure it was worth the extra effort to make two separate doughs. But, I’ve had such great success with all of her recipes that I decided to go for it…so glad I did. They were a huge hit with everyone. Perfect contrast and my kids don’t really love sugary desserts, so I did reduce a bit but loved by the entire crew! Thanks for another winner.
This recipe is fabulous! We like our chocolate cold, so we put the finished batch into the refrigerator. The 5 of us ate the entire batch in two days! Bad for the diet, but it’s a testament to how wonderful this recipe is. Thanks, Jen.
OK, Everyone! Get ready for your tongue to slap your brains out!!! These Brookies are as sinfully good as it gets!!! Seriously! They are so delicious that I can’t adequately describe them. I would proudly serve them to any honored guest who would surely be impressed. They are not only delicious but are beautiful to look at, as well. Follow the instruction exactly for success. Just take my Tennessee word for it and make them! You will forever be a fan!
I don’t see any mention of kneading the dough. Why does the ingredient list include extra flour for kneading? Thanks.
Hi Karen, That’s definitely a mistake; I’ve just updated the recipe. Sorry for any confusion and hope you enjoy the brookies if you make them!
I’ve been baking on Saturday mornings with two of my grandkids via Google Meet, and it’s been a wonderful way to spend time together until we can see each other in person again. We all loved the brookies, as well as your cheesecake bars, which we made in an earlier session. Thanks, Jenn!
What a nice way to stay connected with your grandkids (and glad you enjoyed the brookies)! 🙂
what does the oven need to be heated at??
Hi, The oven temperature should be 350°F/175°C. Hope you enjoy!
Amazing amazing amazing! Perfectly chewy with a bit of saltiness from the cookie dough. Going to become a staple for sure
I used a tiny bit (20g less sugar) and I think I’d use even slightly less next time in the brownie mixture. But otherwise followed recipe exactly. And baked for the stated time too. Was a bit worried about it being undercooked but I always end up burning them!! And needed to let it cool for a couple hours for it to harden up enough to cut.
