Instructions:
Let’s get started on these decadent brookies! We’ll break this down into two main components: the brownie batter and the cookie dough.
Making the Brown Butter for the Cookie Dough
The first crucial step is to brown the butter for our cookie dough. Grab a light-colored saucepan and melt the 3/4 cup of cubed salted butter over medium heat. As it melts, it will start to foam. Keep swirling the pan gently, and watch closely. You’ll begin extract to see tiny brown bits form at the bottom of the pan and the butter will start to smell wonderfully nutty. This process usually takes about 5-8 minutes. Be careful not to burn it! Once it has a rich amber color and a toasty aroma, immediately pour it into a heatproof bowl to stop the cooking. Let it cool slightly while you prepare the brownie batter. This brown butter is going to infuse our cookie layer with an unparalleled flavor.
Preparing the Brownie Batter
In a large heatproof bowl, melt the 14.5 tablespoons of salted butter. You can do this in the microwave in 30-second intervals, stirring in between, or over a double boiler. Once melted, whisk in the dark brown sugar and granulated sugar until well combined. The mixture will look like wet sand. Add the two large eggs, one at a time, whisking well after each addition until the batter is smooth and glossy. Stir in the 1 and 1/2 teaspoons of vanilla extract. Now, it’s time to add the dry ingredients. In a separate medium bowl, whisk together the 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 until just combined. Be careful not to overmix, as this can lead to tough brownies. Finally, gently fold in the 1 and 1/2 cups of chocolate chips. This brownie batter should be thick and fudgy.
Crafting the Brown Butter Chocolate Chip Cookie Dough
Now, let’s move on to our cookie dough. In a separate large bowl, combine the slightly cooled brown butter (from the first step) with the 1/4 cup of vegetable oil. Whisk them together until well incorporated. Add the 3/4 cup of cocoa powder to this wet mixture and stir until you have a smooth, chocolatey base. Next, add the remaining 3 large eggs (make sure they are at room temperature for best results – this helps them emulsify better with the fats) and the remaining 1 and 1/2 teaspoons of vanilla extract. Whisk until everything is well combined and the batter is glossy. Gradually add your dry ingredients to this wet mixture: 1 and 1/2 cups of all-purpose flour (this is separate from the flour for the brownie batter), 1/2 teaspoon of baking soda, and 1/4 teaspoon of salt. Mix until just combined. Finally, stir in the 4 ounces of chopped semi-sweet chocolate. This cookie dough will be softer than traditional cookie dough, which is exactly what we want for a chewy texture.
Assembling and Baking the Brookies
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 it easier to lift the brookies out once baked. Now, for the fun part! Dollop spoonfuls of the brownie batter into the prepared pan, spreading it out to form an even layer. Don’t worry if it’s not perfectly smooth. Then, dollop spoonfuls of the cookie dough randomly over the brownie layer. Using a toothpick or a butter knife, gently swirl the two batters together. You want to create distinct ribbons of brownie and cookie, but avoid over-swirling, or you’ll lose the separate layers.
Bake for 30-35 minutes, or until a toothpick inserted into the center comes out with moist crum extractbs attached (not wet batter). The edges should be set and slightly pulled away from the sides of the pan. Let the brookies cool completely in the pan on a wire rack before cutting them into squares. This is a crucial step for clean cuts and for the brookies to fully set up. Resist the urge to cut them while warm! Once cooled, use the parchment paper overhang to lift the entire slab out of the pan, and then cut into your desired sizes. Enjoy these incredible brown butter brookies with a glass of milk or a cup of coffee!

Frequently Asked Questions:
Can I make brown butter ahead of time?
Absolutely! Brown butter can be made a day or two in advance and stored in an airtight container in the refrigerator. Just let it come to room temperature before using it in the recipe, as it will solidify when chilled.
How do I store leftover brookies?
Store your delicious brown butter brookies in an airtight container at room temperature for up to 3 days. For longer storage, you can refrigerate them, though they might become a little firmer. You can gently reheat them in a low oven or microwave to enjoy that fresh-baked gooeyness.
What if my brown butter solids burn?
It’s easy to accidentally burn brown butter if you’re not watching carefully. If you see black flecks in your butter, it’s likely burnt and will impart a bitter flavor. It’s best to discard it and start over with fresh butter to ensure the best results for your brown butter brookies.
