Instructions:
Part 1: The Brown Butter Brownie Base
First, we’re going to create our incredible brown butter. Take the 180g of butter and place it in a light-colored saucepan over medium heat. As the butter melts, it will start to foam. Keep an eye on it, swirling the pan occasionally. You’ll notice small milk solids forming at the bottom. Continue to cook, watching as these solids turn a golden brown and the butter itself takes on a beautiful amber hue and a nutty aroma. This process usually takes about 5-8 minutes. Once you see those lovely golden-brown bits and smell that distinct caramel scent, 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 while you prepare the chocolate.
In a separate heatproof bowl, combine the 320g of chocolate (broken into pieces if using bars) with 80g of the brown butter (from the initial melting, not the remaining 180g). You can melt these together using a double boiler (a bowl set over a saucepan of simmering water, ensuring the bottom of the bowl doesn’t touch the water) or carefully in the microwave in 30-second intervals, stirring well between each. Stir until the chocolate is completely smooth and glossy. Once melted, set this aside to cool slightly.
In a large mixing bowl, whisk together the 180g granulated sugar, 80g brown sugar, and 2g salt. Then, add the 4 eggs, one at a time, whisking well after each addition until the mixture is well combined and slightly thickened. This is where we build the structure of our brownie. Gradually pour in the slightly cooled melted chocolate mixture, whisking until everything is just combined. Be careful not to overmix at this stage; we want those fudgy brownies!
Now, it’s time to add the dry ingredients for the brownie layer. In a separate bowl, whisk together the 120g all-purpose flour and 50g cocoa powder. Gradually fold these dry ingredients into the wet chocolate mixture using a spatula. Mix until just combined, making sure there are no streaks of flour. If you’re using chocolate chunks or chips, gently fold them in now. This batter will be thick and luscious.
Part 2: The Brown Butter Cookie Dough
-
180 g butter
-
320 g chocolate (for melting)
-
120 g all purpose flour
-
50 g cocoa powder
-
180 g Granulated Sugar
-
80 g brown sugar
-
2 g salt
-
4 eggs
-
120 g chocolate chunks
-
85 g all-purpose flour
-
80 g butter
-
80 g brown sugar
-
40 g granulated sugar
-
1 g salt
-
1 egg
-
Step 1
For the brownie layer: Melt 180g butter in a saucepan over medium heat until it turns a nutty brown. Remove from heat and let cool slightly. In a large bowl, whisk together the melted brown butter, 180g granulated sugar, 80g brown sugar, and 2g salt. Beat in 4 eggs one at a time until well combined. Fold in 320g melted chocolate, 120g all-purpose flour, and 50g cocoa powder until just combined. Pour into a greased and floured 9×13 inch baking pan. -
Step 2
For the cookie layer: In a separate bowl, cream together 80g butter, 80g brown sugar, and 40g granulated sugar until light and fluffy. Beat in 1 egg and 1g salt. Stir in 85g all-purpose flour until just combined. Fold in 120g chocolate chunks, if using. -
Step 3
Dollop spoonfuls of the cookie dough over the brownie batter in the baking pan. -
Step 4
Gently swirl the cookie dough into the brownie batter using a knife or toothpick to create a marbled effect. -
Step 5
Bake in a preheated oven at 350°F (175°C) for 30-35 minutes, or until a toothpick inserted into the center comes out with moist crumbs attached. Do not overbake. -
Step 6
Let cool completely in the pan before cutting into squares.
Now for the cookie layer! In a medium bowl, cream together the remaining 80g butter, 80g brown sugar, and 40g granulated sugar until light and fluffy. This might take a few minutes with an electric mixer, or a bit longer by hand. This creaming process incorporates air, which contributes to the chewy texture of the cookies. Beat in the 1 egg and 1g salt until well combined.
Gradually add the 85g all-purpose flour to the cookie dough mixture, mixing on low speed or with a spatula until just combined. Don’t overmix; we want tender cookies. The dough should be thick but scoopable.
Assembly and Baking
Preheat your oven to 175°C (350°F). Line a 20×20 cm (8×8 inch) baking pan with parchment paper, leaving some overhang on the sides for easy removal.
Spread the brownie batter evenly into the prepared baking pan. Then, dollop spoonfuls of the cookie dough over the brownie batter. Use your spatula or the back of a spoon to gently spread and swirl the cookie dough over the brownie batter, creating those beautiful marbled patterns. Don’t worry about getting it perfectly even; the swirls are part of the charm!
Bake for 30-35 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 layer should look golden brown, and the brownie layer should be fudgy. Overbaking will result in dry brookies, so keep a close eye on them towards the end of the baking time.
Once baked, let the brookies cool completely in the pan on a wire rack. This is crucial for them to set properly and for the flavors to meld. Once completely cool, use the parchment paper overhang to lift the entire block out of the pan. Slice into squares and prepare for pure bliss! These are best enjoyed at room temperature, but a quick zap in the microwave can bring back some of that gooey warmth if you prefer. Enjoy every fudgy, chewy, brown-butter-infused bite!

Frequently Asked Questions:
Can I make the brownie and cookie layers separately?
Absolutely! While the magic happens when they’re layered and baked together, you can certainly bake the brownie layer first and then dollop the cookie dough on top. Just adjust the baking time for the cookie layer to ensure it’s cooked through.
How should I store my brown butter brookies?
Store them in an airtight container at room temperature for up to 3-4 days. If you live in a warm climate, you might want to refrigerate them to maintain their texture. They’re also delicious when gently rewarmed in the oven or microwave.
