Super fudgy, easy cocoa brownies made with rich cocoa powder, melted butter, and pantry staples. Crackly top, chewy center — no chocolate bar required.
10 tbsp unsalted butter
1 1/4 cups granulated sugar
3/4 cup unsweetened cocoa powder (Dutch-processed preferred)
2 large eggs
1/2 tsp vanilla extract
1/2 cup all-purpose flour
1/4 tsp salt
Optional: 1/2 cup chocolate chips or chopped nuts
Preheat oven to 325°F (163°C). Line an 8×8 pan with parchment.
Melt butter in saucepan over low heat. Remove from heat and whisk in cocoa powder and sugar until smooth.
Let cool for 5 minutes. Whisk in eggs one at a time, then vanilla and salt.
Fold in flour until just combined. Add optional mix-ins.
Pour into prepared pan and smooth top.
Bake 28–32 minutes until a toothpick comes out with moist crumbs.
Cool before slicing for clean edges
Use high-quality cocoa powder for best flavor. Add espresso powder to deepen the chocolate. Store in airtight container up to 4 days or freeze up to 2 months.
