Brookies Cookies
Brookies cookies are the ultimate dessert mashup — rich, fudgy brownie dough swirled together with buttery chocolate chip cookie dough, baked into one outrageously delicious bite. These thick, chewy best selling cookies have gone totally viral for good reason, and once you try them, you’ll never look back.
You know that impossible debate — brownies or cookies? What if you never had to choose? That’s literally what brookies cookies are, and honestly, they feel like cheating in the best possible way. I brought a batch of these to a family get-together last summer and they were gone in about eleven minutes flat. I timed it.
These aren’t your average fun chocolate chip cookies with a little cocoa thrown in. We’re talking two fully separate doughs — a proper fudgy brownie cookie dough AND a classic buttery chocolate chip cookie dough — smooshed together into one glorious ball and baked to perfection. Think Brookie Cookie Crumbl vibes, but made right in your own kitchen.

What Makes These Brookies Cookies So Good
Let’s be real: the magic is all in the contrast. You get the deep, chocolatey richness of a brownie on one side and that golden, buttery sweetness of a chocolate chip cookie on the other. Together? Absolute chaos in the best possible way.
The texture is what really makes these the best selling cookies in any room they enter — slightly crisp on the edges, gooey in the center, and so thick you almost feel guilty taking a second one. Almost. They’re also totally customizable, which we’ll get into below.

Pro tip: Dutch-process cocoa is key for that deep, rich brownie flavor. Regular cocoa will work in a pinch, but the color and intensity just won’t be quite the same.
Step-by-Step Instructions

Step 1: Get Your Oven Ready
Preheat your oven to 350°F and line two large baking sheets with parchment paper. Set them aside — you’ll need both. These brookies cookies bake one sheet at a time for the most even results, so patience is part of the process.
Step 2: Make the Brownie Cookie Dough
In the bowl of a stand mixer, beat together the room-temperature butter, brown sugar, and granulated sugar for about 3 minutes until the mixture is light, fluffy, and looks almost mousse-like. This step matters — don’t rush it.
Add the egg and vanilla and mix until fully combined. In a separate bowl, whisk together the flour, Dutch-process cocoa powder, baking soda, and salt. Sift the dry ingredients directly into the butter mixture and mix on low speed until just incorporated and no dry streaks remain.
Using a large spatula, fold in the semi-sweet chocolate chips. The dough will be thick and fudgy — almost like brownie batter that decided to grow up and become a cookie. Set it aside while you tackle the second dough.
Step 3: Make the Chocolate Chip Cookie Dough
Here’s a little twist: the butter for this dough goes in cold and cubed, not softened. Add the cold butter, brown sugar, and granulated sugar to your stand mixer with the paddle attachment. Start on low speed, then gradually increase and cream everything together for about 4 minutes. You’re looking for a pale, fluffy mixture with absolutely no visible butter chunks. Scrape down the sides as you go.
Add the egg and egg yolk one at a time, scraping down the bowl between each addition. Mix in the vanilla. In a separate bowl, whisk together the flour, baking soda, cornstarch, and salt — yes, cornstarch is in there and yes, it makes a difference. It keeps the cookies extra soft and thick.
Add the dry ingredients to the butter mixture in two additions, mixing on low speed until just combined. Do not overmix — this is serious. An overmixed cookie dough leads to tough cookies, and nobody wants that. Fold in the chocolate chips with a spatula and call it done.
Step 4: Roll the Dough Balls
Using a small cookie scoop, portion both doughs into balls. The chocolate chip cookie dough balls should be slightly larger than the brownie cookie dough balls — this keeps the final brookies cookies looking balanced. Roll each ball between your palms to smooth them out. If you want perfectly uniform cookies (and you know you do), use a kitchen scale to weigh them.
Time-saving tip: Roll all the brownie balls first, then all the chocolate chip balls. It’s way more efficient than switching back and forth.
Step 5: Smash Them Together
Take one brownie dough ball and one chocolate chip cookie dough ball, press them together, and roll them into a single unified ball. This is genuinely the most satisfying step. Place each combined dough ball on your prepared baking sheet about 2 inches apart — they will spread.
Step 6: Bake to Perfection
Bake one sheet at a time in the center of the oven for 8 to 9 minutes. You’re looking for edges that are just set and tops that look slightly underdone and fluffy. This is intentional — pull them when they still look a little underbaked, because they’ll continue cooking on the hot pan.
Remove the cookies and let them cool on the baking sheet for 5 to 10 minutes before transferring to a wire rack. Repeat with the second sheet, making sure the pan has cooled down between batches. A hot pan = flat cookies. Don’t skip this.
Finish with a sprinkle of flaky sea salt if you want to feel fancy and honestly, you should. It makes these fun chocolate chip cookies taste genuinely gourmet.
Expert Tips for the Best Brookies Cookies
Don’t Skip the Cold Butter in the Cookie Dough
This is one of the biggest secrets behind thick, bakery-style results. Cold butter slows the spread in the oven, giving you that gorgeous, thick brookie texture. If your butter is too soft, the cookies will flatten out — and that’s just sad.
Use a Kitchen Scale
Eyeballing two different doughs is tricky. A kitchen scale ensures every brookie is identical, which means even baking and a professional-looking result. These genuinely look like Brookie Cookie Crumbl quality when you nail the sizing.
Underbake — Seriously
The number one mistake people make with brookies cookies (and cookies in general) is overbaking. Pull them out when they still look slightly underdone in the center. By the time they cool, they’ll be perfectly set with that chewy, gooey center that makes everyone go wild.
Dutch-Process Cocoa = Deep Flavor
Regular cocoa works, but Dutch-process gives the brownie side a darker, more intense chocolate flavor and a richer color. If you love roasted cherry brownies or anything with deep chocolate flavor, you’ll want to use the Dutch-process here.
Variations and Fun Twists
Add a Nutella Swirl: Flatten each combined dough ball slightly and add a tiny dollop of Nutella in the center before rolling back into a ball. Melted chocolate surprise inside — you’re welcome.
Go Nuts: Fold roughly chopped walnuts or pecans into the brownie cookie dough for some texture and a bit of that classic brownie vibe.
White Chocolate Chips: Swap the semi-sweet chips in the chocolate chip cookie dough for white chocolate chips. The contrast with the dark brownie side is chef’s kiss.
Stuffed Brookies: Press an Oreo or a caramel square into the center of each combined ball before baking. These become the most decadent best selling cookies at any bake sale, guaranteed.
Troubleshooting
My cookies spread too much. The most likely culprit is butter that was too warm. Make sure the cookie dough butter goes in cold and cubed, and if your dough feels soft or greasy before baking, pop it in the fridge for 30 minutes.
The brownie side is dry. You may have overmixed the brownie dough or overbaked. Mix until just combined, and pull the cookies a minute earlier next time.
My cookies look uneven. The two dough balls weren’t the same size, or they weren’t rolled together tightly enough. A kitchen scale solves this almost every time.
Storage Instructions
| Method | Duration | Notes |
|---|---|---|
| Room temperature (airtight container) | Up to 5 days | Place parchment between layers |
| Refrigerator | Up to 1 week | Bring to room temp before serving |
| Freezer (baked cookies) | Up to 3 months | Thaw at room temp for 1–2 hours |
| Freezer (unbaked dough balls) | Up to 3 months | Bake from frozen, add 2–3 minutes |
Reheating Tips
Pop a cookie in the microwave for about 10–12 seconds and it tastes freshly baked. Just don’t overdo it or you’ll end up with a cookie puddle. For a crispier edge, reheat in a 300°F oven for about 5 minutes.
No-Waste Kitchen Ideas
Leftover brownie cookie dough? Press it into a small pan and bake as brownies — nobody needs to know. Extra chocolate chip cookie dough balls freeze beautifully and can be baked fresh whenever the craving hits. And if you have broken cookies? Crumble them over vanilla ice cream. Problem solved.

FAQs About Brookies Cookies
Can I make brookies cookies ahead of time?
Absolutely — in fact, they might even be better the next day once everything settles. You can make both doughs up to 48 hours ahead, store them separately in the fridge, and then roll and bake when you’re ready. Or roll the combined balls, refrigerate them overnight, and bake fresh the next morning.
Do I have to use a stand mixer?
A stand mixer makes things easier, especially for the chocolate chip cookie dough where you’re creaming cold butter, but a hand mixer works fine too. Just make sure you’re using low speed when adding the dry ingredients so you don’t kick flour everywhere. Ask me how I know.
Can I freeze the dough?
Yes! Roll the combined dough balls, place them on a tray to freeze solid, then transfer to a zip-lock bag. Bake straight from frozen at 350°F, just add 2–3 extra minutes. This is honestly one of the best decisions you can make — fresh brookies cookies on demand.
Why use cornstarch in the chocolate chip cookie dough?
Cornstarch keeps the cookies soft, thick, and tender — it’s one of those small additions that makes a big difference. It’s the same trick used in many fun chocolate chip cookies recipes and even bakery-style shortbreads. Don’t skip it.
Can I make these without a cookie scoop?
You can, but a cookie scoop really helps with consistent sizing, which is extra important here since you’re dealing with two different doughs. If you don’t have one, use a tablespoon and do your best to eyeball equal portions — a kitchen scale as a backup helps a lot.
