Instructions:
Part 1: The Brown Butter Cookie Dough
1. Begin extract by browning 14.5 tablespoons of salted butter. Place this butter in a light-colored saucepan over medium heat. As the butter melts, it will foam. Swirl the pan occasionally. You’ll notice milk solids at the bottom of the pan starting to turn golden brown. Keep a close eye on it, as this process can go from perfect to burnt very quickly. Once you see small, fragrant brown flecks and the butter smells nutty and toasty, immediately remove it from the heat and pour it into a heat-safe bowl to stop the cooking. Let it cool slightly. This browned butter is the secret weapon for incredible flavor!
2. In a large bowl, combine the cooled browned butter with 3/4 cup of packed dark brown sugar and 3/4 cup of granulated sugar. Whisk them together until well combined and no dry pockets of sugar remain. Then, add 2 large eggs, one at a time, whisking well after each addition until the mixture is smooth and slightly lighter in color. Stir in 1 and 1/2 teaspoons of vanilla extract.
3. In a separate medium bowl, whisk together 3 cups of all-purpose flour, 1 teaspoon of baking soda, 1 teaspoon of baking powder, and 1/2 teaspoon of salt. Gradually add the dry ingredients to the wet ingredients, mixing on low speed or by hand until just combined. Be careful not to overmix the dough. Finally, gently fold in 1 and 1/2 cups of chocolate chips. This forms your delicious cookie dough layer. Set this dough aside.
Part 2: The Fudgy Brownie Batter
4. Now, let’s prepare the brownie batter. In a medium saucepan, melt 3/4 cup of cubed salted butter over medium-low heat. Once melted, whisk in 1/4 cup of vegetable oil and 4 ounces of chopped semi-sweet chocolate (or chocolate chips). Continue to stir until the chocolate is completely melted and the mixture is smooth. Remove from heat and stir in 3/4 cup of cocoa powder until fully incorporated. The mixture will be thick and glossy.
5. In a separate bowl, whisk together 3 large eggs and 3/4 cup of granulated sugar until well combined and the mixture becomes slightly frothy. Gradually pour the warm chocolate-butter-oil mixture into the egg mixture, whisking constantly until everything is smooth and emulsified. You’ll have a luscious, fudgy brownie batter.
Part 3: Assembling and Baking the Brookies
6. Preheat your oven to 350°F (175°C). Grease and flour a 9×13 inch baking pan, or line it with parchment paper, leaving an overhang on the sides to make lifting the brookies out easier.
7. Pour about two-thirds of the cookie dough into the prepared baking pan and gently press it down to form an even layer. You can use your hands or the bottom of a measuring cup. Don’t worry if it’s not perfectly smooth; the texture will be part of the charm.
8. Carefully pour the brownie batter over the cookie dough layer, spreading it evenly to cover the entire surface. Then, dollop the remaining one-third of the cookie dough randomly over the brownie layer. You can use a spoon to gently spread and swirl some of the cookie dough into the brownie batter for a marbled effect, or leave them as distinct dollops.
9. Bake for 30-40 minutes, or until the edges are set and a toothpick inserted into the center comes out with moist crum extractbs attached (not wet batter). The brownie portion should be fudgy, and the cookie portion should be baked through but still soft.
10. Let the brookies cool completely in the pan on a wire rack before cutting them into squares. This is crucial for clean cuts and allows the textures to set properly. Once cooled, lift them out of the pan using the parchment paper overhang. Cut into bars and prepare for the rave reviews! Enjoy every decadent bite of these Brown Butter Brookies.

I love serving these warm, with a scoop of vanilla bean ice cream melting into the gooey chocolate. They’re also fantastic on their own with a glass of cold milk or a hot cup of coffee.

You could also fold in chopped nuts like walnuts or pecans for extra crunch. I wholeheartedly encourage you to give this brown butter brookies recipe a try. I promise, you won’t regret it!
Frequently Asked Questions:

No problem at all! You can easily make these brookies by hand using a sturdy whisk and a good amount of elbow grease. Ensure your butter is softened enough to cream with sugar, and beat well for the best results.
