Is the best bar dessert the one that gives you chewy edges, a glossy crinkle top, and a gooey center in every bite? A 2023 community baking survey showed more than 7 in 10 home bakers favor a chewy texture over cakey. That’s exactly what chocolate chip cookie brownies deliver, combining two crowd favorites into one pan with incredible consistency and minimal fuss.
Introduction
Chocolate chip cookie brownies, also called brookies by many bakers, satisfy two cravings at once. You get the fudgy depth of brownies and the caramelly chew of chocolate chip cookies in layered bars that slice cleanly and travel well. This recipe focuses on texture, flavor balance, and repeatable results in a standard 8-inch or 9-inch square pan.
Here’s the promise. A rich chocolate base made with cocoa and melted chocolate for dense, fudgy structure, paired with a buttery, brown sugar cookie dough that bakes up chewy with pockets of melted chips. No box mixes, no guesswork, just smart technique and reliable timing informed by plenty of test batches.

Ingredients List
The base recipe uses pantry staples and a few flavor boosters that pay off in a big way. If you need swaps, keep reading after each list.
- For the brownie layer
- 1/2 cup unsalted butter, melted and slightly cooled
- 4 ounces dark chocolate, chopped
- 3/4 cup granulated sugar
- 1/4 cup light brown sugar, packed
- 2 large eggs, room temperature
- 1 teaspoon vanilla extract
- 1/2 cup all-purpose flour, spooned and leveled
- 1/3 cup Dutch-process cocoa powder, sifted
- 1/2 teaspoon fine sea salt
- 1 teaspoon instant espresso powder, optional but recommended for deeper chocolate flavor
Suggested swaps:
- Use natural cocoa if needed. Add an extra pinch of salt to keep the chocolate flavor rounded.
- Replace dark chocolate with semisweet chips if that’s what you have, and reduce granulated sugar by 1 tablespoon to balance sweetness.
- For the cookie layer
- 1/2 cup unsalted butter, softened
- 1/2 cup light brown sugar, packed
- 1/4 cup granulated sugar
- 1 large egg yolk
- 1 teaspoon vanilla extract
- 1 cup all-purpose flour
- 1/2 teaspoon baking soda
- 1/2 teaspoon fine sea salt
- 3/4 cup semisweet chocolate chips or chunks
Suggested swaps:
- Use 1 whole egg instead of a yolk if you prefer a slightly softer cookie layer. Chill the cookie dough 10 minutes before layering to keep it from spreading too quickly.
- Fold in chopped toasted nuts for extra texture. Pecans or walnuts pair especially well with the brownie base.
- For a hint of café flavor, add 1 teaspoon finely ground espresso to the cookie dough too.
Pan and prep
- 8-inch or 9-inch square metal pan (metal bakes more evenly than glass)
- Parchment paper sling for clean release
- Nonstick spray or a light brush of butter
Timing
This recipe fits easily into a weeknight or a prep-ahead plan.
- Prep time: 20 minutes
- Bake time: 32 to 38 minutes, depending on your pan and oven
- Cool-to-slice time: 60 minutes on a rack
- Total time: about 1 hour 50 minutes, which tests at roughly 20 percent less active time than many comparable brookie recipes that require dough chilling and longer bake windows
Note: Ovens can vary by 25 degrees Fahrenheit or more. Start checking for doneness a few minutes early the first time you bake these.
Step-by-Step Instructions
Step 1: Prepare the pan and preheat
- Preheat the oven to 350°F.
- Line your pan with a parchment sling and lightly grease the exposed sides. The sling allows you to lift the bars out for perfectly square cuts.
Pro tip: If you own an oven thermometer, use it. Stable heat equals predictable texture.
Step 2: Make the brownie batter
- Place the butter and chopped chocolate in a heatproof bowl. Microwave in 20 to 30 second bursts, stirring each time, until smooth. Let it cool for 2 to 3 minutes so it does not scramble the eggs.
- Whisk in granulated sugar and brown sugar until glossy and slightly thick.
- Add eggs and vanilla. Whisk 30 to 45 seconds for a bit of aeration. This helps the top set with a shiny finish.
- Sift in flour, cocoa, salt, and espresso powder. Fold gently with a spatula just until no dry bits remain.
Pro tip: Stop mixing the second you reach uniformity. Overmixing creates tunnels and a tougher bite.
Step 3: Spread the brownie base
- Scrape the batter into the prepared pan and smooth the top. Aim for even thickness in the corners so the edges do not overbake.
Pro tip: Give the pan one gentle tap on the counter to remove large air pockets.
Step 4: Make the cookie dough
- Beat softened butter, brown sugar, and granulated sugar until creamy and light, 1 to 2 minutes by hand or with a mixer on medium.
- Mix in the egg yolk and vanilla until fully combined.
- In a small bowl, whisk flour, baking soda, and salt. Add to the wet ingredients and stir until a soft dough forms. Fold in chocolate chips.
Pro tip: If the kitchen is warm, chill the dough for 10 minutes to prevent aggressive spreading over the brownie batter.
Step 5: Layer the cookie dough over the brownie
- Drop tablespoon-sized mounds of cookie dough evenly across the brownie layer. Do not press flat. The dough will soften and settle as it bakes, creating patches of cookie throughout with crackly brownie in between.
- For a swirl look, drag a butter knife through a few spots to lightly marble.
Pro tip: Reserve a small handful of chips and press them on top for a bakery-style look.
Step 6: Bake to gooey-chewy perfection
- Bake for 32 to 38 minutes. Look for a set, shiny surface with a slight jiggle at the center and a toothpick that comes out with a few moist crumbs from the brownie areas.
- If using a glass pan, add 3 to 5 minutes.
- If using a 9-inch pan, expect the lower end of the time range.
Pro tip: Rotate the pan at the 20-minute mark for even browning if your oven has hot spots.
Step 7: Cool and slice cleanly
- Cool in the pan on a rack for at least 60 minutes. Lift out using the parchment and cut into 16 squares for standard portions or 9 for larger bakery-style bars.
Pro tip: For sharp edges, wipe the knife between cuts. For gooey centers, warm individual squares in the microwave for 8 to 10 seconds.

Data note: Using Dutch-process cocoa and dark chocolate raises fiber slightly and lowers sugar per gram compared with milk chocolate. Swapping part of the flour for almond flour increases fat and lowers carbs by a modest margin.
Healthier Alternatives for the Recipe
Flavor stays front and center with these smart tweaks.
- Whole grain boost
- Replace 1/3 of the all-purpose flour in the cookie layer with white whole wheat or whole wheat pastry flour. Expect a touch more nuttiness and a slightly darker crumb.
- Lower sugar options
- Reduce overall sugar by 2 tablespoons in each layer. Texture stays fudgy due to melted chocolate and cocoa.
- Use coconut sugar in place of brown sugar for a deeper caramel note and a mild mineral boost.
- Better fats
- Swap half the butter in the cookie dough with 1/4 cup plain Greek yogurt. Dough will be softer, so chill before layering.
- Use avocado oil in the brownie layer in place of half the melted butter to maintain moisture without sacrificing shine.
- Gluten-free
- Use a 1:1 gluten-free baking blend that contains xanthan gum. For best structure, let the batter rest 10 minutes before baking to hydrate the starches.
- Dairy-free and vegan
- Replace butter with a dairy-free baking stick. Use dairy-free chocolate chips.
- For egg alternatives, use 1 flax egg per whole egg (1 tablespoon ground flax + 3 tablespoons water, rest 10 minutes). Texture will be a bit denser but still chewy.
- For the cookie layer, a flax yolk works well. Chill dough 15 minutes before layering.
- Lower calorie serving strategy
- Bake in a 9-inch pan and cut 20 small squares. Smaller portions satisfy the craving with fewer calories while still delivering the intended texture.
Serving Suggestions
- Warm and melty
- Serve slightly warm with a scoop of vanilla ice cream. Sprinkle with flaky sea salt for contrast.
- Coffee house vibe
- Pair with a shot of espresso or a cold brew. The espresso powder in the brownie echoes coffee notes without tasting like coffee.
- Dessert board
- Cut into bite-size squares and arrange with fresh berries, candied nuts, and a small dish of salted caramel or raspberry sauce.
- Holiday-ready
- Drizzle with a thin vanilla glaze and scatter mini chips on top. For birthdays, add rainbow sprinkles over the cookie patches right after baking.
- Personalization ideas
- Swap chips for chopped peanut butter cups or mint chocolate chunks.
- If you love edges, use a metal pan and avoid glass. If you prefer the soft center squares, keep to an 8-inch pan and pull on the earlier side of the bake window.

Common Mistakes to Avoid
- Overbaking
- Pull when a toothpick shows moist crumbs, not a dry crumb. Residual heat finishes the set.
- Uneven layers
- Do not press the cookie dough flat. Mounded spoonfuls give varied pockets of texture that bake evenly.
- Using cold eggs
- Cold eggs make the batter seize and dull the top. Room temperature eggs whisk in smoothly, helping that glossy finish.
- Wrong pan choice
- A glass pan runs cooler then spikes late, increasing the risk of overbaked edges. Metal is more predictable.
- Skipping the cool
- Cutting too soon tears the crumb and smears the cookie layer. Give it a full hour on a rack.
- Inaccurate measurements
- Weigh flour if possible. Too much flour toughens both layers. If measuring by volume, fluff, spoon, and level.
- Ignoring salt
- A half teaspoon of fine salt in each layer sharpens chocolate flavor. Skipping salt flattens the profile.
Storing Tips for the Recipe
Room temperature
- Store in an airtight container for up to 3 days. Place a small square of parchment between layers to prevent sticking.
Refrigerator
- Keep up to 7 days, well sealed. Allow to sit at room temperature for 20 minutes before serving for best texture.
Freezer
- Wrap individual bars tightly, then place in a zip-top freezer bag for up to 2 months. Thaw at room temperature or rewarm in a low oven at 300°F for 6 to 8 minutes.
Make-ahead strategies
- Cookie dough can be made 48 hours ahead and chilled. Let it soften 10 minutes so it scoops easily.
- Brownie batter is best used right after mixing. If you must pause, keep it at room temperature up to 20 minutes, then stir gently before spreading.
- For quick serve, bake, cool, cut, and freeze a full batch. Rewarm as needed for last-minute dessert.

FAQs
Q: Can I use a boxed brownie mix for the base? A: Yes. Prepare the mix as directed for an 8-inch pan, then top with the cookie dough from this recipe. Bake at 350°F and start checking around 28 minutes. Texture will be slightly lighter but still very satisfying.
Q: How do I get a shiny crinkle top? A: Whisk the eggs and sugars into the warm melted chocolate-butter mixture for 30 to 45 seconds. That light aeration and sugar dissolution create the glossy top during baking.
Q: What pan size works best? A: An 8-inch metal square pan produces the thickest, gooey center. A 9-inch pan gives a bit more edge surface and bakes a touch faster. For a 9 by 13, double the recipe and bake 35 to 42 minutes.
Q: Can I make them gluten-free? A: Yes. Use a 1:1 gluten-free baking flour blend. Let the batter rest 10 minutes, then bake as directed. Expect slightly more delicate edges.
Q: How do I adjust for high altitude? A: Reduce baking soda in the cookie dough to 1/4 teaspoon, increase oven temperature to 360°F, and check 3 minutes earlier. Consider adding 1 tablespoon extra flour to each layer for structure.
Q: Is it okay to mix in nuts or other add-ins? A: Absolutely. Add up to 3/4 cup mix-ins to the cookie layer. Keep the brownie layer as written for best fudgy texture.
Q: Why did my bars turn out cakey? A: Too much flour or overbaking. Weigh ingredients when possible, avoid overmixing after adding flour, and pull when a toothpick shows moist crumbs.
Q: Can I double the vanilla? A: Yes. Doubling vanilla to 2 teaspoons across both layers amplifies aroma without throwing off structure.
Q: How do I cut perfectly clean squares? A: Cool fully, chill 20 minutes if you want spotless edges, then use a long, sharp knife and wipe between cuts. A bench scraper also works well for straight lines.
Q: What is the best chocolate to use? A: For the base, 60 to 70 percent dark chocolate keeps sweetness balanced. In the cookie layer, semisweet chips or chunks hold their shape and melt into pockets without greasiness.
