Ingredients You’ll Need
- 6 tablespoons (85 grams) unsalted butter: This adds richness to your cookie layer. Be sure to melt it just until hot for the best texture.
- 1/2 cup (100 grams) light brown sugar: Brown sugar contributes moisture and chewyness to the cookies, enhancing flavor with its molasses content.
- 1/4 cup (50 grams) granulated sugar: For that right amount of sweetness and crunch.
- 1 large egg: Binding agent that brings the dough together.
- 1 teaspoon vanilla extract: Adds a warm, inviting aroma and deep flavor.
- 1 1/4 cups (159 grams) all-purpose flour: The backbone of the cookie, providing structure.
- 1/2 teaspoon fine sea salt: Enhances the overall flavor profile.
- 1/4 teaspoon baking powder: Helps the cookies rise and stay soft on the inside.

- 4 tablespoons (57 grams) unsalted butter (for brownie batter): Provides moisture and richness to the brownie layer.
- 3/4 cup plus 2 tablespoons (175 grams) granulated sugar (for brownie batter): Sweetness for the decadent fudgy center.
- 1 large egg plus 1 egg yolk, cold: A cold yolk results in rich brownie texture.
- 1/2 cup (43 grams) cocoa powder: Essential for that deep chocolaty flavor in the brownies.
- 1/4 cup (56 grams) neutral oil (like vegetable or avocado): Adds moisture without affecting flavor.
- 1/4 cup plus 2 tablespoons (48 grams) all-purpose flour (for brownie batter): Provides structure while still keeping it fudgy.
- 2 teaspoons cornstarch: Helps create a softer brownie texture.
- 1/4 teaspoon fine sea salt (for brownie batter): Balances the sweetness and enhances flavor.

- Flaky sea salt (optional): A finishing touch that heightens the flavor contrast.
How to Make Brookies
- Preparation: Preheat your oven to 325°F. Line an 8 by 8-inch metal pan with parchment paper, leaving an overhang on the sides for easy removal later. Don’t forget to spray it with nonstick cooking spray!
- Make the Cookie Layer: In a large microwave-safe bowl, heat 6 tablespoons of unsalted butter in 30-second intervals until completely melted. Remove from the microwave and stir in 1/2 cup of light brown sugar and 1/4 cup of granulated sugar. Mix to combine, letting the mixture cool until it’s just warm.
- Incorporate Egg and Vanilla: Once cooled, whisk in 1 large egg and 1 teaspoon of vanilla extract until the mixture is smooth.
- Add Dry Ingredients: Using a rubber spatula, gently stir in 1 1/4 cups of all-purpose flour, 1/2 teaspoon of fine sea salt, and 1/4 teaspoon of baking powder. Lastly, fold in 1/2 cup of semisweet chocolate chips, and chill the dough in the fridge while preparing the brownie layer.
- Prepare the Brownie Layer: Repeat the previous melting process with another 4 tablespoons of unsalted butter in a large microwave-safe bowl. Combine with 3/4 cup plus 2 tablespoons of granulated sugar, mixing well, then allow to cool slightly.
- Mix Brownie Batter: Vigorously whisk in 1 large egg and 1 cold egg yolk for about 1 minute. Then, whisk in 1/2 cup of cocoa powder, 1/4 cup of neutral oil, and 1 teaspoon of vanilla extract. With a rubber spatula, stir in 1/4 cup plus 2 tablespoons of all-purpose flour, 2 teaspoons of cornstarch, and 1/4 teaspoon of fine sea salt until just combined. Gently fold in 1/2 cup of semisweet chocolate chips.
- Assemble the Layers: Scoop out nine 1-tablespoon portions of cookie dough and set them aside. Spread the remaining cookie dough in an even layer across the prepared pan. Don’t stress about it being perfect; just make sure it’s roughly even.
- Add Brownie Batter: Pour the brownie batter on top of the cookie layer and spread it evenly.
- Top with Reserved Cookie Dough: Gently flatten the reserved cookie dough balls and place them on top of the brownie batter, allowing some of the brownie to peek through.
- Bake: Place the pan in the preheated oven and bake for 33-38 minutes. Aim for 33 minutes if you prefer a gooey, fudgy center or closer to 38 minutes for a chewier texture. The edges should be set and the cookies slightly browned.
- Finishing Touch: Once done, sprinkle with flaky sea salt if desired. Let cool completely in the pan before lifting out and slicing.
Storing & Reheating
Brookies can be stored at room temperature for up to 3 days in an airtight container. For longer freshness, refrigerate them in a sealed container for up to a week. If you’d like to freeze them, wrap individually in plastic wrap, then store in a freezer-safe bag for up to 3 months. When you’re ready to enjoy, just pop them in a microwave for about 15-20 seconds to warm; they’ll taste just as fresh. Do note that texture may slightly change after freezing, but warming them will help refresh that mouthwatering consistency.
Chef’s Helpful Tips
- Make sure the butter is just melted, not boiling, to prevent the sugars from cooking.
- Using cold eggs for the brownie layer creates a richer texture; this is a handy trick if your kitchen is warm.
- If you like a more intense chocolate flavor in the brownie, try adding an extra tablespoon of cocoa powder.
- Let the Brookies cool completely for better slicing—warm brownie and cookie edges can crumble.
- Consider adding nut pieces into either layer for extra flavor and crunch if you’re not allergic.
- You can prepare the cookie dough and brownie batter a day in advance and assemble them the next day for a convenient baking process.
These Brookies encapsulate the best of both worlds—a chewy cookie layered on top of a rich, fudgy brownie. Whipping up this recipe guarantees deliciousness while also bringing joy to those lucky enough to taste them. Feel free to experiment with flavors and toppings that suit your style; perhaps some crushed nuts or a sprinkle of cinnamon could be fun! Enjoy every gooey bite, and relish in being the star baker among friends and family. Who wouldn’t want that?
