Brownie cookies are the ultimate hybrid — chewy, fudgy, and filled with intense chocolate flavor, featuring shiny tops and rich centers.
1/2 cup (1 stick) unsalted butter
4 oz semi-sweet or dark 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
1/2 tsp baking powder
1/4 tsp salt
Optional: 1/2 cup chocolate chips or chopped nuts
Melt butter and chopped chocolate until smooth. Let cool slightly.
Stir in sugars and vanilla.
Add eggs one at a time, whisking until glossy and thick.
Sift in cocoa powder, flour, baking powder, and salt. Mix just to combine.
Fold in any add-ins. Chill dough for 20–30 minutes.
Scoop onto lined baking sheets. Bake at 350°F for 10–12 minutes.
Let cool on sheet 5 minutes, then transfer to wire rack.
Chill dough to prevent spreading.
Don’t overbake — centers should remain soft.
Store airtight for 4–5 days or freeze baked cookies.
