Every bite is decadent, gooey, and irresistibly chocolatey.
Whether you’re baking for a party, a cozy night in, or just because, these brookies will make you everyone’s favorite dessert maker.
Why You’ll Love These Brown Butter Brookies
- Two Desserts in One: You get the dense, fudgy richness of brownies and the chewy, buttery goodness of cookies in every bite.
- Nutty Brown Butter Flavor: Browning the butter for the cookie dough gives these brookies a subtle caramelized, nutty depth that sets them apart.
- Perfect Crinkly Tops: With the right whisking technique, your brownies will bake up with that coveted shiny, crackly crust.
- Chocolate Lover’s Dream: Between melted chocolate, chocolate chunks, and chocolate chips, these brookies are pure indulgence.
The Secret to Crinkly Brownie Tops
If you’ve ever wondered how bakeries get that shiny, crackly top on their brownies, here’s the trick: whisk the eggs and sugars thoroughly. Whisk for 2–3 minutes until the mixture is thick, pale, and smooth. This dissolves the sugar, which creates the glossy crust during baking. Don’t skip this step—it makes your brookies look and taste professional.
Ingredients
Brownie Batter
- 180 g unsalted butter
- 320 g semi-sweet chocolate (about 60%), chopped
- 120 g all-purpose flour
- 50 g cocoa powder
- 180 g granulated sugar
- 80 g brown sugar
- 2 g salt
- 4 large eggs
- 120 g chocolate chunks (optional, for extra gooeyness)
Brown Butter Cookie Dough
- 80 g unsalted butter
- 80 g brown sugar
- 40 g granulated sugar
- 1 g salt
- 1 large egg
- 2 g vanilla extract
- 85 g all-purpose flour
- 70 g chocolate chips
- Extra chocolate chunks for topping
How to Make Brown Butter Brookies
1. Make the Brown Butter Cookie Dough
- Melt 80 g butter in a small saucepan over medium heat. Stir occasionally until the butter turns golden brown and smells nutty. Remove from heat and let cool slightly.
- In a bowl, mix the brown butter with brown sugar, granulated sugar, and salt until smooth.
- Whisk in the egg and vanilla until fully combined.
- Fold in the flour and chocolate chips just until incorporated—don’t overmix.
- Chill the dough in the fridge while you prepare the brownie batter.
2. Make the Brownie Batter
- Preheat your oven to 329°F (165°C) and line an 8×8-inch baking pan with parchment paper.
- Melt butter and chopped chocolate in a heatproof bowl over simmering water (or in short bursts in the microwave), stirring until smooth. Cool slightly.
- In a separate bowl, whisk together granulated sugar, brown sugar, and eggs for 2–3 minutes until thick and pale.
- Sift together the flour, cocoa powder, and salt.
- Combine the melted chocolate mixture with the egg-sugar mixture, then gently fold in the dry ingredients.
- Fold in the chocolate chunks for an extra chocolatey bite.
3. Assemble and Bake
- Spread half of the brownie batter into your prepared pan.
- Add chunks of the chilled cookie dough on top.
- Spread the remaining brownie batter over the cookie dough.
- Top with more cookie dough chunks and chocolate chunks for a bakery-style finish.
- Bake for 45–55 minutes, until the edges are set and a toothpick comes out with moist crumbs (not wet batter).
4. Cool and Slice
Let the brookies cool completely in the pan to set the layers. Once cool, lift out using the parchment and cut into squares or rectangles.
Tips for the Best Brookies
- Don’t skip the egg-sugar whisking for that shiny brownie top.
- Chill the cookie dough so it holds its shape in the oven.
- Cool completely before slicing for clean, picture-perfect pieces.
- Storage: Keep brookies in an airtight container at room temperature for 3–4 days, or freeze for up to 2 months.
These Brown Butter Brookies are the ultimate indulgence—gooey, chocolatey, and completely irresistible. Serve them warm with a scoop of vanilla ice cream for an unforgettable dessert.
