Ingredients

• For the Brown Butter:
• 1 cup (2 sticks) unsalted butter
• For the Fudgy Brownie Layer:
• 1 cup granulated sugar
• 2 large eggs
• 1 teaspoon vanilla extract
• 1/2 cup all-purpose flour
• 1/4 cup unsweetened cocoa powder
• 1/4 teaspoon salt
• 1/2 cup semi-sweet chocolate chips
• For the Chewy Chocolate Chip Cookie Layer:
• 1/2 cup packed light brown sugar
• 1/4 cup granulated sugar
• 1 large egg yolk
• 1 teaspoon vanilla extract
• 1 1/4 cups all-purpose flour
• 1/2 teaspoon baking soda
• 1/4 teaspoon salt
• 1 cup semi-sweet chocolate chips

Instructions

1. Brown the Butter: In a light-colored saucepan, melt the 1 cup of unsalted butter over medium heat. Continue cooking, stirring occasionally, until the butter turns golden brown and nutty-smelling, with small brown bits forming at the bottom. Immediately remove from heat and pour into a heatproof bowl. Let cool for 10-15 minutes.
2. Prepare for Baking: Preheat your oven to 350°F (175°C). Line an 8×8 inch baking pan with parchment paper, leaving an overhang on two sides, then lightly grease.
3. Make the Brownie Layer: To one half (approx. 1/2 cup) of the slightly cooled brown butter, add the granulated sugar, eggs, and vanilla extract. Whisk until well combined and smooth. In a separate bowl, whisk together the flour, cocoa powder, and salt. Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Fold in the 1/2 cup semi-sweet chocolate chips. Set aside.
4. Make the Cookie Layer: In a medium bowl, combine the remaining 1/2 cup of brown butter (which should be cooled to room temperature and slightly solidified) with the light brown sugar and granulated sugar. Beat with an electric mixer on medium speed until light and fluffy (about 2-3 minutes). Beat in the egg yolk and vanilla extract until combined.
5. In a separate small bowl, whisk together the 1 1/4 cups all-purpose flour, baking soda, and salt. Gradually add the dry ingredients to the wet ingredients, mixing on low speed until just combined. Stir in the 1 cup semi-sweet chocolate chips.
6. Assemble the Brookies: Spread the brownie batter evenly into the prepared 8×8 inch pan. Dollop spoonfuls of the chocolate chip cookie dough over the brownie layer. Use a knife or skewer to gently swirl the two batters together, creating a marbled effect.
7. Bake: Bake for 30-35 minutes, or until the edges are set and a toothpick inserted into the cookie parts comes out with moist crumbs (not wet batter). Be careful not to overbake.
8. Cool and Serve: Remove from the oven and let cool completely in the pan on a wire rack before lifting out with the parchment paper overhang and cutting into squares.
