How to Make Brown Butter Brookies

1. Prep: Preheat your oven to 350℉. Spray a 9×13 metal pan with nonstick spray and line with parchment paper (this makes for easy removal and slicing later).

2. Make the Chocolate Chip Cookie Dough: Melt 14.5 tbsp of salted butter in a large mixing bowl. Whisk in the dark brown sugar and granulated sugar. Add the eggs and vanilla extract, whisking until smooth and combined, about 30-45 seconds. Stir in the dry ingredients: 3 cups of all-purpose flour, 1 tsp baking soda, 1 tsp baking powder, and 1/2 tsp salt, then fold in 1 and 1/2 cups chocolate chips.

3. Divide the Dough: Split the dough into two equal halves (about 640 grams each). Press half of the dough into the prepared pan, then lift out that piece of parchment paper and replace with a new piece. Set aside the remaining dough.

4. Brown the Butter: In a medium saucepan over medium heat, melt 3/4 cup cubed salted butter. Stir occasionally. Once melted, reduce heat to medium-low, stirring frequently until the butter becomes foamy and golden with a nutty aroma—this should take about 3-6 minutes.

5. Make the Brownie Batter: Once browned, stir in the chopped semi-sweet chocolate until melted, followed by 1/4 cup vegetable oil and 3/4 cup cocoa powder. In a large mixing bowl, whisk together 3 large eggs, 1 egg yolk, and 3/4 cup granulated sugar for 1-2 minutes until smooth. Then whisk in 1 and 1/2 cups powdered sugar, 2 tsp vanilla extract, and 1/4 tsp salt. Ensure the chocolate mixture is warm but not hot, then whisk it into the egg mixture. Fold in 1/2 cup all-purpose flour and a pinch of espresso powder, if using, along with 1 cup chocolate chips.

6. Assemble: Carefully spread slightly more than half of the brownie batter in the bottom of your lined 9×13 pan. Lay the cookie dough sheet on top, removing that extra piece of parchment paper and replacing it back. Spread the remaining brownie batter over everything. Form thick discs with the remaining dough and place on top of the brownie layer, then press extra chocolate chips into any bare spots.

7. Bake: Bake the assembled brookies for 38 to 44 minutes. The cookies will be golden and the brownies should have a shiny top. A toothpick inserted in the brownie layer should have moist crumbs but no wet batter. Be careful not to overbake!

8. Serve & Store: Let the bars cool in the pan on a wire rack for 1 to 2 hours before slicing. Sprinkle with flaky sea salt if desired. Store leftovers in an airtight container at room temperature for 3-4 days. For a warm delight, I highly recommend reheating slices in the microwave!

Variations & Creative Twists

• Nutty Brookies: Add 1 cup of chopped nuts like walnuts or pecans for a crunchy surprise.
• Mint Chocolate Brookies: Incorporate a few drops of mint extract into the brownie layer for a refreshing twist.
• Snickerdoodle Brookies: Replace the chocolate chips in the cookie layer with cinnamon and sugar for a warm, spiced flavor.
• Creamy Peanut Butter Swirl: Swirl creamy peanut butter into the brownie mixture before layering for a rich and nutty flavor combination.
