Ingredients:
Brownie Layer Preparation:
This is where the magic begin extracts, and the key to achieving that wonderfully dense and fudgy texture.
1. Begin extract by melting the 180g of butter in a saucepan over medium heat. Once melted, add your 320g of chopped chocolate. Stir gently and continuously until both are completely melted and smoothly combined. Be patient here; you don’t want to scorch the chocolate. Once melted, remove from the heat and let it cool slightly. This cooling period is important so we don’t cook the eggs when we add them.
2. In a separate medium bowl, whisk together the 120g of all-purpose flour, 50g of cocoa powder, 180g of granulated sugar, 80g of brown sugar, and 2g of salt. Make sure there are no lumps and everything is well incorporated. This dry mixture forms the backbone of our brownie layer, providing structure and that classic chocolatey depth.
3. In another bowl, lightly whisk the 4 eggs. Gradually pour the slightly cooled chocolate-butter mixture into the dry ingredients, whisking until just combined. Then, gently fold in the whisked eggs. Be careful not to overmix here. Overmixing can develop the gluten in the flour too much, leading to a tougher brownie instead of a fudgy one. If you’re using them, gently fold in the 120g of chocolate chunks now. This brownie batter will be thick and glossy.
Cookie Layer Preparation:
Now for the star of the show – the brown butter! This step is crucial for that signature nutty flavor and aroma.
4. In a light-colored saucepan, melt the 80g of butter over medium heat. Continue to cook the butter, swirling the pan occasionally, until it turns a beautiful golden-brown color and smells nutty. Watch closely, as it can go from perfectly browned to burnt very quickly. You’ll see little brown bits form at the bottom of the pan. This is the milk solids toasting, and it’s where all that amazing flavor comes from. Once browned, immediately remove from the heat and carefully pour it into a heatproof bowl, making sure to scrape in those flavorful brown bits. Let it cool for about 10-15 minutes.
5. To the cooled brown butter, add 80g of brown sugar, 40g of granulated sugar, and 1g of salt. Whisk until well combined. Then, whisk in the single egg until the mixture is smooth and slightly creamy. This will be your cookie dough base.
6. In a separate bowl, combine the 85g of all-purpose flour. Gradually add the flour to the brown butter mixture, mixing until just combined. Again, avoid overmixing. You want a soft, slightly sticky cookie dough.
Assembly and Baking:
It’s time to bring these two delicious layers together!
7. Preheat your oven to 175°C (350°F). Grease and line a 23cm x 23cm (9-inch x 9-inch) baking pan with parchment paper, leaving some overhang on the sides to make lifting the brookies out easier.
8. Pour the brownie batter into the prepared baking pan and spread it evenly to cover the bottom.
9. Dollop spoonfuls of the cookie dough randomly over the surface of the brownie batter. You can use a spoon or a small cookie scoop for this. Don’t worry about making it perfectly even; the rustic look is part of the charm.
10. Using a knife or a skewer, gently swirl the cookie dough into the brownie batter. Create streaks and marbled patterns. This ensures you get both flavors in every bite and also helps to distribute the cookie dough. Be careful not to swirl too much, or the layers will completely blend.
11. Bake for 30-40 minutes, or until the edges of the brookies are set and a toothpick inserted into the center comes out with moist crum extractbs attached (not wet batter). The cookie topping should be golden brown.
12. Let the brookies cool completely in the pan on a wire rack before lifting them out using the parchment paper overhang. This is a crucial step for clean cuts and preventing them from falling apart. Once completely cooled, slice into squares and enjoy the ultimate brownie-cookie mashup!
