Ingredients:
Preparing the Brown Butter
The foundation of these brookies’ incredible flavor is the brown butter. Don’t skip this step! It transforms ordinary butter into something magical. You’ll need to brown the 14.5 tablespoons of butter first for the cookie layer. Place the butter in a light-colored saucepan over medium heat. As the butter melts, it will foam. Continue to cook, swirling the pan occasionally, until the foam subsides and you start to see golden-brown flecks forming at the bottom of the pan. This process should take about 5-8 minutes. The aroma will be wonderfully nutty and toasty. Immediately remove the pan from the heat and pour the brown butter into a heatproof bowl to stop the cooking process. Let it cool slightly.
Making the Cookie Dough Layer
In a large bowl, combine the cooled brown butter with the packed dark brown sugar and granulated sugar. Whisk them together until well combined and slightly fluffy. This mixture will smell divine already! Next, add the 2 room-temperature large eggs, one at a time, whisking well after each addition. Stir in the 1 and 1/2 teaspoons of vanilla extract. 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 on low speed or by hand until just combined. Be careful not to overmix. Finally, gently fold in the 1 and 1/2 cups of chocolate chips. The cookie dough will be thick and incredibly tempting to eat raw, but resist the urge!
Crafting the Brownie Layer
For the brownie layer, you’ll need to brown the additional 3/4 cup of salted butter. Follow the same browning process as described earlier, ensuring you get those beautiful golden-brown milk solids at the bottom of the pan. Let this brown butter cool slightly. In a medium saucepan over low heat, melt the chopped semi-sweet chocolate (or chocolate chips) with the 1/4 cup of vegetable oil and the cooled brown butter. Stir continuously until the chocolate is completely melted and smooth. Remove from heat and whisk in the 3/4 cup of cocoa powder until fully incorporated. In a separate bowl, whisk together the 3 room-temperature large eggs and 1/2 cup of granulated sugar (you can use some of the remaining granulated sugar from the cookie ingredients if you have it leftover, or just measure out a new 1/2 cup) until pnon-alcoholic ale and slightly thickened. Gradually whisk the warm chocolate mixture into the egg mixture until everything is smooth and glossy.
Assembling and Baking the Brookies
Preheat your oven to 350°F (175°C). Grease and line a 9×13 inch baking pan with parchment paper, leaving an overhang on the sides to help with lifting out the finished brookies. This is a crucial step for easy removal. First, press the cookie dough evenly into the bottom of the prepared baking pan. Make sure it covers the entire base. Don’t worry if it’s not perfectly smooth; the baking process will even it out. Next, carefully pour the brownie batter over the cookie dough layer. Gently spread the brownie batter to cover the cookie dough evenly, using an offset spatula or the back of a spoon. For a beautiful marbled effect, you can swirl a bit of the brownie batter into the cookie dough layer with a knife or toothpick, but be careful not to overdo it and mix them too much.
Now it’s time to bake! Place the pan in the preheated oven and bake for 30-40 minutes. The brookies are done when the edges are set and a toothpick inserted into the center comes out with moist crum extractbs attached (not wet batter). The brownie layer should look set but still slightly fudgy. It’s important not to overbake them, as this can result in dry brookies. Once baked, remove the pan from the oven and let the brookies cool completely in the pan on a wire rack. This cooling process is essential for them to set properly and for easier cutting. Once completely cooled, use the parchment paper overhang to lift the entire block out of the pan. Cut into squares and prepare for pure bliss. Enjoy every single decadent bite of your homemade Brown Butter Brookies!
