Ingredients You’ll Need
- 6 tablespoons (85 grams) unsalted butter: Essential for moistness and flavor. Ensure it’s melted for the cookie layer.
- 1/2 cup (100 grams) light brown sugar: Brings a caramel-like richness. You can substitute with dark brown sugar for a deeper taste.
- 1/4 cup (50 grams) granulated sugar: Adds sweetness and crunch.
- 1 large egg: Binds ingredients together for a tender texture.
- 1 teaspoon vanilla extract: Vital for flavor; use pure vanilla extract for the best results.
- 1 1/4 cups (159 grams) all-purpose flour: The backbone for both layers. Measure precisely for best results.
- 1/2 teaspoon fine sea salt: Enhances the flavors and balances the sweetness.
- 1/4 teaspoon baking powder: Adds lift to the cookie layer.
- 1/2 cup (95 grams) semisweet chocolate chips: Adds melty pockets of chocolate—use milk or dark chocolate for a twist.
- 4 tablespoons (57 grams) unsalted butter: For the brownie layer, melting ensures a smooth batter.
- 3/4 cup plus 2 tablespoons (175 grams) granulated sugar: Provides sweetness and helps create that chewy texture.
- 1 large egg plus 1 egg yolk, cold: The extra yolk adds richness to the brownies.
- 1/2 cup (43 grams) cocoa powder: For that deep chocolate flavor; Dutch-process cocoa enhances richness but regular cocoa works too.
- 1/4 cup (56 grams) neutral oil (like vegetable or avocado): Keeps the brownies moist and fudgy.
- 1 teaspoon vanilla extract: Again, for flavor enhancement; definitely don’t skip this!
- 1/4 cup plus 2 tablespoons (48 grams) all-purpose flour: For the brownie layer’s structure; measure accurately.
- 2 teaspoons cornstarch: Helps create that desired fudgy texture.
- 1/4 teaspoon fine sea salt: Again, to balance the sweetness in the brownies.
- 1/2 cup (95 grams) semisweet chocolate chips: More chocolatey goodness folded in makes these brownies irresistible.
- Flaky sea salt (optional): A sprinke now and then enhances flavors and adds an impressive touch.
How to Make Brookies
- Preheat the Oven: Start by setting your oven to 325°F. Line an 8 by 8-inch metal pan with parchment paper, leaving an overhang. This makes for easy lifting and slicing later; then, spray it with a little nonstick cooking spray to prevent sticking.
- Prepare Cookie Dough: In a large microwave-safe bowl, melt the 6 tablespoons of unsalted butter in 30-second increments. Once melted, add the 1/2 cup light brown sugar and 1/4 cup granulated sugar. Stir well to combine.
- Mix in Egg and Vanilla: Let the mixture cool until just warm. Whisk in 1 egg and 1 teaspoon of vanilla extract until smooth.
- Combine Dry Ingredients: Gently fold in 1 1/4 cups all-purpose flour, 1/2 teaspoon fine sea salt, and 1/4 teaspoon baking powder using a rubber spatula. Finally, gently mix in 1/2 cup semisweet chocolate chips. Now chill this dough in the fridge while you prepare the brownie layer—don’t skip this step, as the cold dough is easier to work with!
- Prepare Brownie Batter: In another large microwave-safe bowl, heat 4 tablespoons unsalted butter until melted. Add 3/4 cup plus 2 tablespoons granulated sugar and whisk to combine. Allow this mixture to cool until just warm.
- Whisk Eggs: Vigorously whisk in 1 large egg and 1 egg yolk for a full minute; it helps create a nice, airy texture in your brownies.
- Add Cocoa and More: Stir in 1/2 cup cocoa powder, 1/4 cup neutral oil, and 1 teaspoon vanilla extract. With a rubber spatula, fold in 1/4 cup plus 2 tablespoons all-purpose flour, 2 teaspoons cornstarch, and 1/4 teaspoon fine sea salt until everything is just combined. Add the remaining 1/2 cup semisweet chocolate chips for that extra melty goodness!
- Assemble the Brookies: Scoop out nine 1-tablespoon portions of cookie dough and set them aside in a small bowl. Press the remaining cookie dough into the bottom of the prepared pan, spreading it in an even layer. Then, pour the brownie batter over it, spreading it evenly as well.
- Top with Cookie Dough: Flatten the reserved cookie dough balls slightly with your palms and place them atop the brownie batter, allowing some brownie batter to peek through.
- Bake: Bake at 325°F for 33-38 minutes. You’ll know they’re ready when the edges are set, and the cookie tops have very lightly begun to brown. For a gooey center, aim for closer to 33 minutes; for a chewier texture, go up to 38 minutes.
- Finishing Touches: Once out of the oven, sprinkle with flaky sea salt for an extra touch of flavor! Allow the Brookies to cool in the pan completely before lifting them out and slicing.
Storing & Reheating
To store leftover Brookies, keep them covered at room temperature for up to 3 days for the best freshness. If you have more baked than you can finish, refrigerate them in an airtight container for up to a week. For longer storage, freeze them for up to 3 months. Just thaw them in the fridge overnight before enjoying! If they feel a little dry after freezing, a quick zap in the microwave for about 15 seconds can bring back some moisture and warmth.
Chef’s Helpful Tips
- To avoid a dry texture, be sure not to overbake your Brookies. Trust the toothpick test; it should come out slightly moist from the brownies.
- For best results, use room temperature eggs, but remember to keep your butter and chocolate warm.
- Experiment with chocolate chips! Mix in white chocolate, butterscotch, or even peanut butter chips for a fun twist.
- If you’re short on time, prepare the dough a day ahead and refrigerate it overnight, making assembly quick and easy when you’re ready to bake.
- Don’t hesitate to sprinkle a few extra chocolate chips on top before baking—it adds a lovely presentation.
Brookies are a delightful treat that merges the rich fudginess of brownies with the chewy sweetness of cookies. They’re simple enough to whip up on a whim and decadent enough to impress guests at any gathering. So go ahead and experiment with the flavors you love, and don’t be surprised when everyone asks for seconds. Enjoy each bite as you revel in the deliciousness of your homemade creation!

Recipe FAQs

Check for a set edge with a slightly soft center. If you insert a toothpick, it should come out with a few moist crumbs; this ensures you’ll get that wonderful gooey texture!

To keep them fresh and maintain their moist texture, store them in an airtight container at room temperature. If you want them to last longer, freezing is a great option! Just remember to thaw before enjoying again.
