Decadent ultra-fudgy brownies made with nutty brown butter and dark chocolate. Crackly on top, gooey in the center—perfect for serious chocolate lovers.
¾ cup (170g) unsalted butter
6 oz (170g) dark chocolate (60–70%), chopped
1 cup granulated sugar
½ cup brown sugar
3 large eggs
1½ tsp vanilla extract
½ cup all-purpose flour
¼ cup cocoa powder
½ tsp salt
1 tsp espresso powder (optional)
Brown the butter in a saucepan. Remove from heat and stir in chocolate until melted. Cool slightly.
In a large bowl, whisk eggs, sugars, and vanilla until thick and glossy (1–2 minutes).
Slowly mix in the warm chocolate mixture.
Sift in flour, cocoa powder, salt, and espresso powder. Fold gently to combine.
Pour into a parchment-lined 8×8-inch pan and smooth the top.
Bake at 350°F (175°C) for 28–32 minutes, or until a toothpick comes out with moist crumbs.
Cool completely before slicing. Chill for clean cuts.
Chill before slicing for the best texture.
Add caramel, nuts, or chips for variations.
