Ingredients You’ll Need

Classic pantry staples combine to make Chocolate Chip Cookie Brownies, proving that simple ingredients can lead to smashing success. Every element here brings its magic—whether it’s richness, crunch, flavor, or texture—so don’t skip a thing!

• Unsalted butter (1 cup, melted and divided): Melting half for each layer ensures both cookie and brownie sides are ultra-moist and rich.
• Granulated sugar (1 cup): Sweetens the brownie layer and helps create that signature crackly top.
• Brown sugar, packed (1 cup): Brings caramel notes and chewiness, perfect for classic cookie dough flavor.
• Large eggs (2): Offer structure and tenderness to both layers—one per batter!
• Vanilla extract (2 teaspoons): Don’t underestimate how vanilla pulls the cookie and brownie flavors together.
• All-purpose flour (1 1/4 cups): Gives body to the layers, and you’ll measure it in two parts.
• Baking soda (1/2 teaspoon): Adds lift to the cookie dough for those little pockets of soft crumb.
• Salt (1/2 teaspoon): Makes every bite pop, balancing out all the sweetness.
• Semi-sweet chocolate chips (1 1/2 cups, divided): Loads up both layers with melty chocolate—save some for the top, if you like!
• Unsweetened cocoa powder (1/2 cup): Creates the deep, decadent base for your brownie layer.
• Vegetable oil (2 tablespoons): Keeps the brownie side extra fudgy and dense.
• Baking powder (1/2 teaspoon): Gives just the right amount of brownie rise, so they don’t come out flat.

How to Make Chocolate Chip Cookie Brownies

Step 1: Prep Your Pan and Oven

Start off by getting your 9×13-inch baking pan ready for action. Either line it with parchment paper for easy removal or grease it lightly with butter or nonstick spray. Preheat your oven to 350°F (175°C) so it’s hot and ready when your layers come together.

Step 2: Whip Up the Cookie Layer

In a large bowl, combine 1/2 cup melted butter, the brown sugar, 1 egg, and 1 teaspoon vanilla. Stir with enthusiasm until the mixture is smooth and creamy—no lumps here! Add in 1 cup flour, baking soda, and 1/4 teaspoon salt. Stir gently until just combined; overmixing leads to tougher cookies. Fold in 3/4 cup chocolate chips for that classic gooey surprise in every bite.

Step 3: Mix the Brownie Batter

Grab a second bowl for your brownie mix. Combine the remaining 1/2 cup melted butter, granulated sugar, 1 egg, and 1 teaspoon vanilla. Stir well, then add in the cocoa powder, vegetable oil, baking powder, 1/4 teaspoon salt, and 1/4 cup flour. Keep mixing until everything is nicely combined. Fold in the last 3/4 cup of chocolate chips so every square has rich chocolatey bits throughout.

Step 4: Layer and Swirl

Spread the brownie batter across the bottom of your prepared pan using a spatula or the back of a spoon, getting it all the way into the corners. Drop spoonfuls of cookie dough all across the top—don’t worry if it looks patchy! Gently spread the cookie dough over the brownie layer without fully mixing the two. You want visible pockets of brownie and cookie for that “brookie” effect.

Step 5: Bake to Perfection

Slip the pan into your preheated oven and bake for 30 to 35 minutes. Check for doneness by inserting a toothpick into the center—it should come out with just a few moist (not wet!) crumbs. If you love extra fudgy brownies, take them out at the lower end of the baking time. Let the pan cool completely before slicing into beautiful, bold bars.

How to Serve Chocolate Chip Cookie Brownies

Garnishes

You can drizzle warm Chocolate Chip Cookie Brownies with melted chocolate or caramel sauce, sprinkle on flaky sea salt, or shower them with a dusting of powdered sugar. Fresh berries or a scoop of your favorite ice cream transform them into an unforgettable plated dessert.

Side Dishes

Pair these brownies with a big glass of cold milk for classic comfort, or serve alongside fresh fruit to add a bright contrast to all that rich chocolate. Coffee or hot cocoa makes a dreamy companion for an afternoon pick-me-up.

Creative Ways to Present

Stack cut bars in a tall tower for a stunning centerpiece, or wrap individual squares in wax paper and twine for picnic-perfect or lunchbox-ready treats. You can even crumble them over ice cream for DIY sundaes or turn leftovers into trifles layered with whipped cream or pudding.

Make Ahead and Storage

Storing Leftovers

Chocolate Chip Cookie Brownies keep beautifully at room temperature for up to 3 days in an airtight container. If your kitchen runs especially warm, tuck them in the fridge to preserve their gooey texture and prevent the chocolate from getting too soft.

Freezing

If you want to bake ahead, these bars freeze very well! Once cooled completely, cut them into portions and wrap each bar tightly in plastic wrap, then transfer to a freezer bag. They’ll stay fresh for up to three months—just let them thaw at room temperature for a few hours before indulging.

Reheating

For that fresh-from-the-oven experience, pop a brownie bar into the microwave for 10 to 15 seconds. This brings back the melty chocolate chips and gooey, buttery centers that make these treats truly irresistible.

FAQs

Can I add nuts or other mix-ins?

Absolutely! Feel free to fold in a handful of chopped walnuts, pecans, or even white chocolate chips to the cookie or brownie layer. This simple addition brings an extra boost of flavor and texture, making your Chocolate Chip Cookie Brownies uniquely your own.

How will I know if they’re done baking?

Check for doneness by inserting a toothpick into the center after about 30 minutes. If it comes out with moist crumbs (but not raw batter), you’re good to go. Remember, slightly underbaking gives you extra fudgy, ultra-decadent bars!

Can I use salted butter instead of unsalted?

If you’re opting for salted butter, just reduce the additional salt by a pinch to balance things out. Salted butter works in a pinch and still provides all the rich, buttery goodness these brownies need.

Should I wait until they’re fully cool before slicing?

For cleaner, sharper bars, let your Chocolate Chip Cookie Brownies cool completely before cutting. If you like extra gooey pieces and don’t mind a little mess, you can dive in sooner—freshly baked bars are an undeniable treat!

How should I store leftovers if I want them to stay soft?

Keep them in an airtight container at room temperature, adding a slice of bread to the container to help retain moisture. This little trick keeps your brownies deliciously soft for days.
