Rich, gooey, and deeply chocolatey, these easy fudgy brownies are made from scratch in one bowl—ready in under 40 minutes.
1/2 cup unsalted butter (113g)
4 oz semi-sweet chocolate (chopped or chips)
1 cup granulated sugar
1/4 cup brown sugar (optional)
2 large eggs
1 tsp vanilla extract
1/4 cup unsweetened cocoa powder
1/2 cup all-purpose flour
1/4 tsp salt
Optional: 1/2 cup chocolate chips, chopped nuts, or espresso powder
Preheat oven to 350°F (175°C). Line an 8×8 pan with parchment.
Melt butter and chocolate together until smooth. Cool slightly.
Whisk in sugars, then eggs one at a time. Mix in vanilla.
Sift in cocoa powder. Stir to combine.
Fold in flour and salt until just combined. Add mix-ins if using.
Pour into pan, smooth top, and bake 22–28 minutes.
Cool in pan before slicing.
For fudgier brownies, slightly underbake.
For a shiny top, beat eggs and sugar well.
Freeze baked brownies for up to 2 months.
