Ingredients

• For the Brown Butter Chocolate Chip Cookie Dough:
• 1 cup (2 sticks) unsalted butter
• 3/4 cup granulated sugar
• 3/4 cup packed light brown sugar
• 2 large eggs
• 1 teaspoon vanilla extract
• 2 1/4 cups all-purpose flour
• 1 teaspoon baking soda
• 1/2 teaspoon salt
• 1 1/2 cups semi-sweet chocolate chips (or a mix of your favorite chocolates)
• For the Fudgy Brownie Batter:
• 1/2 cup (1 stick) unsalted butter, melted
• 1 cup granulated sugar
• 2 large eggs
• 1 teaspoon vanilla extract
• 1/2 cup all-purpose flour
• 1/2 cup unsweetened cocoa powder
• 1/4 teaspoon baking powder
• 1/4 teaspoon salt
• 1/2 cup chocolate chips (optional, for extra fudginess)

Instructions

1. Preheat your oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper, leaving an overhang on the sides for easy removal.
2. First, make the brown butter for the cookie dough: In a medium saucepan, melt 1 cup of unsalted butter over medium heat. Continue cooking, stirring occasionally, until the butter turns a rich golden-brown color and smells nutty. Be careful not to burn it. Immediately remove from heat and pour into a heat-proof bowl to cool slightly (about 10-15 minutes).
3. While the brown butter cools, prepare the brownie batter: In a large bowl, whisk together the melted 1/2 cup butter, 1 cup granulated sugar, eggs, and vanilla extract until well combined. In a separate bowl, whisk together the 1/2 cup flour, cocoa powder, baking powder, and salt. Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Fold in the optional 1/2 cup chocolate chips. Set aside.
4. Now, finish the cookie dough: Once the brown butter has cooled slightly (it should still be liquid but not scalding hot), pour it into a large mixing bowl. Add the 3/4 cup granulated sugar and 3/4 cup brown sugar, and beat with an electric mixer on medium speed until creamy. Beat in the 2 eggs one at a time, then stir in the 1 teaspoon vanilla extract.
5. In a separate bowl, whisk together the 2 1/4 cups flour, 1 teaspoon baking soda, and 1/2 teaspoon salt. Gradually add the dry ingredients to the wet ingredients, mixing on low speed until just combined. Fold in the 1 1/2 cups chocolate chips by hand.
6. Assemble the Brookies: Drop spoonfuls of the cookie dough evenly into the prepared baking pan, covering about two-thirds of the bottom. Spread gently with the back of a spoon if needed. Then, dollop spoonfuls of the brownie batter over the remaining cookie dough. Using a knife or a skewer, gently swirl the brownie and cookie doughs together to create a marbled effect, being careful not to overmix.
7. Bake for 30-35 minutes, or until the edges are set and lightly golden, and a toothpick inserted into the center comes out with moist crumbs (not wet batter). The center may look slightly undercooked, but it will set as it cools.
8. Remove from the oven and let cool completely in the pan on a wire rack before lifting out by the parchment paper and cutting into squares. Enjoy!
