Ingredients

• 1 cup (2 sticks) unsalted butter, divided
• 1/2 cup granulated sugar (for cookie dough)
• 1/4 cup packed light brown sugar (for cookie dough)
• 1 large egg yolk
• 1 teaspoon vanilla extract (for cookie dough)
• 1 1/4 cups all-purpose flour (for cookie dough)
• 1/2 teaspoon baking soda
• 1/4 teaspoon salt (for cookie dough)
• 1 cup chocolate chips (milk, semi-sweet, or a mix – for cookie dough)
• 1 cup granulated sugar (for brownie batter)
• 2 large eggs (for brownie batter)
• 1 teaspoon vanilla extract (for brownie batter)
• 1/2 cup all-purpose flour (for brownie batter)
• 1/2 cup unsweetened cocoa powder
• 1/2 teaspoon salt (for brownie batter)
• 1 cup chocolate chips (optional, for brownie batter)

Instructions

1. **Brown the Butter:** In a medium saucepan, melt the entire 1 cup (2 sticks) of unsalted butter over medium heat. Continue cooking, stirring occasionally, until the butter turns a rich golden-brown color and nutty aroma emerges, with brown bits forming at the bottom. Be careful not to burn it. Immediately pour the browned butter into two separate heatproof bowls, dividing it equally (1/2 cup in each). Let cool for at least 15-20 minutes until slightly solidified but still pliable.
2. **Prepare the Brown Butter Chocolate Chip Cookie Dough:** In a large bowl, cream together the 1/2 cup cooled browned butter, 1/2 cup granulated sugar, and 1/4 cup brown sugar until light and fluffy. Beat in the egg yolk and 1 teaspoon vanilla extract until well combined. In a separate small bowl, whisk together 1 1/4 cups flour, 1/2 teaspoon baking soda, and 1/4 teaspoon salt. Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Fold in the chocolate chips. Set aside.
3. **Prepare the Brown Butter Fudgy Brownie Batter:** In another large bowl, whisk together the 1/2 cup cooled browned butter and 1 cup granulated sugar until smooth. Whisk in the 2 large eggs and 1 teaspoon vanilla extract until well combined and slightly frothy. In a separate small bowl, whisk together 1/2 cup flour, 1/2 cup cocoa powder, and 1/2 teaspoon salt. Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Fold in the optional chocolate chips.
4. **Preheat and Prepare Pan:** 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 lifting. Lightly grease the parchment paper.
5. **Assemble the Brookies:** Spread the brownie batter evenly into the prepared baking pan. Drop spoonfuls of the cookie dough over the brownie layer. Use a spoon or your fingers to gently spread and press the cookie dough to mostly cover the brownie layer, leaving some brownie peeking through for a marbled effect. You don’t need to be perfect; the goal is an even distribution.
6. **Bake:** Bake for 30-35 minutes, or until the edges are set and a toothpick inserted into the cookie portion comes out with moist crumbs (not wet batter). The center may still look slightly soft, which is perfect for fudginess.
7. **Cool and Serve:** Let the brookies cool completely in the pan on a wire rack before lifting them out using the parchment paper overhang. This is crucial for them to set properly and prevent crumbling. Once cooled, cut into squares and enjoy your ultimate dessert bliss!
