Ingredients for brookie recipe using brownie mix and cookie dough
Just 12 ingredients for a dessert that tastes like a restaurant-worthy surprise—fudgy brownie meets gooey cookie dough magic.
| Ingredient | Amount | Notes |
|---|---|---|
| Boxed Brownie Mix 🍫 | 1 box | Fudgy chocolate variety preferred |
| Large Eggs 🥚 | 2 whole | Room temperature for even mixing |
| Unsalted Butter 🧈 | ½ cup | Melted, full-fat for richness |
| Milk 🥛 | ½ cup | Whole milk for creaminess |
| Vanilla Extract 🌸 | 1 tsp | Pure extract, not imitation |
| Cookie Dough 🍪 | 1 ½ cups | Store-bought or homemade |
| Semi-Sweet Chocolate Chips 🍫 | ½ cup | For extra richness in cookie dough |
| All-Purpose Flour 🌾 | ¼ cup | If thickening cookie dough |
| Granulated Sugar 🍚 | ¼ cup | For cookie dough sweetness |
| Baking Powder 🧂 | ½ tsp | For brownie mix lift |
| Salt 🧂 | ¼ tsp | Kosher salt preferred |
| Vegetable Oil 🫒 | ¼ cup | For brownie mix |
The brownie mix makes this easy, but Betty Crocker or Duncan Hines fudgy chocolate are the gold standards—avoid cakey mixes. Cookie dough is where you can get creative: Ben & Jerry's or Trader Joe's brands are my go-to for store-bought, but homemade is even better. For that, grab Nestlé Toll House chocolate chips (the good stuff, not the mini ones) and keep the dough thick—it should hold its shape when scooped. Eggs and butter should be at room temp, or the cookie dough will be tough. Pro tip: melt the butter in the microwave for 40 seconds—just until it's liquid, not hot.
No brownie mix? Boxed cake mix plus 1/4 cup cocoa powder works in a pinch (add extra oil). Store-bought cookie dough? Check the label—some brands have weird additives. For homemade, swap chocolate chips for white chocolate or butterscotch chips if you want a twist. Need to make it gluten-free? King Arthur gluten-free flour blend in the cookie dough does the trick. The brownie layer is forgiving—if your mix calls for eggs, use them; if not, skip. The cookie dough layer is where texture matters most—don't overmix it, or you'll end up with dense brookies instead of gooey ones.
Brookies are best served warm, straight from the oven, but they keep well for 3 days in an airtight container at room temp. Reheat in the oven at 350°F for 5-10 minutes to restore that gooey center. Freeze extras on a tray first, then transfer to a bag for up to 3 months. Double the batch—these disappear fast. And if anyone asks, yes, you can add a sprinkle of flaky sea salt on top before baking. Trust me on that.

Step-by-step instructions for decadent double-layered brookies
Here's how to create the ultimate dessert fusion—rich brownie layers topped with gooey cookie dough.
Prepare the Cookie Dough Layer
In a medium bowl, combine the 1.5 cups cookie dough with the 0.5 cup semi-sweet chocolate chips. Mix gently to distribute the chocolate evenly—you want pockets of melted chocolate throughout, not a uniform blend. If your cookie dough is too soft, fold in the 0.25 cup all-purpose flour and 0.25 cup granulated sugar to help it hold its shape when baked.
Spread this mixture evenly into a greased 8x8-inch baking pan, pressing down lightly so it forms a solid layer. The dough should be about ½-inch thick—this ensures it bakes through without burning on top. Don't worry if it looks messy; the beauty of brookies is in the imperfect layers.
Mix the Brownie Batter
In a separate large bowl, whisk together the 1 box brownie mix, 2 whole large eggs, the 0.5 cup melted unsalted butter, 0.5 cup milk, 1 teaspoon vanilla extract, 0.5 teaspoon baking powder, and 0.25 teaspoon salt. Mix just until combined—overmixing develops gluten and makes the brookies dense. The batter should be thick but pourable.
I like to scrape the sides of the bowl with a rubber spatula to ensure all the brownie mix is fully incorporated. This step is crucial for that classic fudgy texture. If the batter looks too thick, add 1 tablespoon of the vegetable oil to help it spread evenly over the cookie dough layer.
Layer and Bake for Perfect Texture
Pour the brownie batter evenly over the cookie dough layer in the pan. Use a spatula to spread it smoothly, creating a clean separation between the two layers. Gently tap the pan on the counter a few times to release any air bubbles that might have formed during pouring.
Bake in a preheated 350°F oven for 25-30 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs but no wet batter. The edges should be set, but the top should still look slightly underbaked—this ensures the cookie dough layer stays gooey in the center.
Cool and Cut for Maximum Indulgence
Remove the brookies from the oven and let them cool in the pan for 10 minutes. This brief resting period allows the layers to set slightly, making them easier to cut. While cooling, you'll notice the cookie dough layer puffing up slightly—this is the magic happening!
Transfer the pan to a wire rack and let cool completely before cutting into 16 squares. The contrast of warm, gooey cookie dough with the rich, fudgy brownie base is what makes brookies irresistible. Serve at room temperature for the best texture—this lets the flavors meld perfectly while keeping the cookie dough soft and chewy.
Pro Tips For Making Brookie Recipe Using Brownie Mix And Cookie Dough
- MIX COOKIE DOUGH LAST: I used to fold in the cookie dough right after mixing the brownie batter, and the result was always a sad, dense brookie. Instead, let the brownie mix sit for 5 minutes after adding the wet ingredients—this relaxes the gluten just enough so the cookie dough swirls stay distinct and gooey, not blended into a brick.
- USE ROOM-TEMP BUTTER: Cold butter from the fridge will create pockets of unmelted fat in your brookies, leaving you with dry, crumbly bites. Take the butter out 30 minutes before mixing, or even better, microwave it for 10 seconds to soften it slightly—just enough to blend smoothly but not turn into soup.
- DON’T OVERMIX THE BATTER: Once you add the cookie dough to the brownie mix, resist the urge to stir like you’re trying to win a baking competition. A few gentle folds are all it takes—overmixing breaks down the cookie dough’s texture, turning your pretty swirls into a muddy, uniform mess. Think "marble, not mud."
- BAKE UNTIL EDGES ARE SET: The biggest rookie mistake (pun intended) is pulling brookies out when the center still looks jiggly. Wait until the edges are firm but the middle has a slight wobble—it’ll finish cooking as it cools. If you cut into them too soon, you’ll end up with a gummy center and a cookie-dough landslide. A toothpick with a few moist crumbs is fine; a wet one means more time.
Essential equipment for this recipe
Essential Baking Tools
You don’t need a fancy kitchen to make perfect brookies, but a few key tools make all the difference. Start with an 8x8-inch baking pan—I recommend a light-colored metal pan like Wilton’s Perfect Results for even baking.
These pans distribute heat evenly, preventing the cookie dough from burning while the brownie layer sets. 🧑🍳
A rubber spatula (like the OXO Good Grips) is a game-changer for spreading the brownie batter smoothly over the cookie dough. It helps create that clean separation between layers without tearing.
For mixing, a medium-sized mixing bowl (I use Pyrex) and a whisk work perfectly for combining ingredients without overmixing. If you’re making homemade cookie dough, a hand mixer (like the KitchenAid KHM500) saves time and effort.
Must-Have Mixing Gear
For the brownie layer, a small offset spatula helps scrape every last bit of batter from the bowl—no wasted chocolate! If you’re using store-bought cookie dough, a measuring cup (like OXO’s Good Grips) ensures you get the right amount for a thick, even layer.
For homemade dough, a dough scraper (I love the Benchmark) keeps things tidy and prevents sticking to your counter.
Precision Equipment
A digital kitchen scale (like the OXO Good Grips) is optional but helpful for measuring ingredients like flour and sugar precisely. This ensures your cookie dough stays just thick enough to hold its shape during baking.
For timing, a timer (I use my phone’s, but a KitchenAid timer is handy) alerts you when the brookies are done—no overbaking!
Budget-Friendly Swaps
No fancy tools? No problem! Use a standard 8-inch square pan (even glass works in a pinch) and a wooden spoon for mixing. A butter knife can replace a spatula for spreading batter, though it might leave slightly uneven edges.
The key is patience—let the brookies cool completely before cutting for clean squares. Trust me, the texture is worth the wait! 💪

Frequently asked questions
Can I use cake mix instead of brownie mix for brookies?
Yes, but you'll need to adjust for the right texture! Mix 1 box cake mix with ¼ cup cocoa powder and ¼ cup vegetable oil to mimic brownie density. Add 1 extra egg if your cake mix requires it. The key is keeping the batter thick enough to hold its shape over the cookie dough layer.
How do I keep the cookie dough layer gooey instead of dry?
Underbaking is the secret! Remove brookies when the toothpick has moist crumbs (not wet batter). The cookie dough needs 2-3 minutes of residual heat to finish cooking after you take them out. For extra gooeyness, chill the baked brookies for 10 minutes before cutting.
What's the best way to make homemade cookie dough for brookies?
Use 1 cup softened butter, ¾ cup brown sugar, ½ cup granulated sugar, 1 egg, 1 tsp vanilla, and 2 cups flour (plus ½ tsp salt). Fold in 1 cup chocolate chips last. Keep it cold—chill the dough for 30 minutes before using to prevent spreading in the oven.
Can I make brookies ahead of time?
Bake them 1 day ahead and store at room temperature in an airtight container. Reheat in a 350°F oven for 5 minutes to restore gooeyness. For longer storage, freeze baked brookies (uncut) for up to 3 months. Thaw overnight in the fridge before serving.
Why did my brookies turn out cakey instead of fudgy?
Overmixing or using cakey brownie mix are the usual culprits. Use a fudgy brownie mix and mix just until combined—lumps are fine! Also, ensure your cookie dough layer is ½-inch thick and don't overbake. The cookie dough should puff slightly when done.
