Ultra-fudgy brownies with a rich, gooey center, crackly top, and deep chocolate flavor — perfect for any chocolate lover.
1/2 cup (1 stick) unsalted butter
4 oz semi-sweet chocolate, chopped
3/4 cup granulated sugar
1/4 cup light brown sugar (optional)
2 large eggs, room temperature
1 tsp vanilla extract
1/3 cup unsweetened cocoa powder
1/2 cup all-purpose flour
1/4 tsp salt
Optional: 1/2 tsp espresso powder, 1/2 cup chopped nuts or chocolate chips
Preheat oven to 325°F (165°C). Line an 8×8-inch pan with parchment paper or grease lightly.
Melt butter and chopped chocolate in a heatproof bowl over simmering water, stirring until smooth.
Stir in granulated and brown sugar while mixture is warm. Add vanilla.
Whisk in eggs, one at a time, beating well after each.
Sift in cocoa powder, flour, and salt. Gently fold into wet mixture until just combined.
Fold in optional add-ins.
Pour batter into prepared pan and smooth the top.
Bake 30–35 minutes, until a toothpick comes out with moist crumbs.
Cool completely before slicing.
For cleaner slices, chill before cutting.
Add flaky sea salt on top for contrast.
Store in an airtight container at room temp for 3 days or freeze for up to 2 months.
