Deeply chocolatey, ultra-fudgy cookies with a shiny crackled top and chewy center — like the best part of a brownie in cookie form.
8 oz dark chocolate, chopped
½ cup (1 stick) unsalted butter
2 large eggs
¾ cup granulated sugar
¼ cup brown sugar (optional)
1 tsp vanilla extract
½ cup all-purpose flour
¼ cup cocoa powder
½ tsp baking powder
½ tsp salt
½ tsp espresso powder (optional)
Melt chocolate and butter together; cool slightly.
Whisk eggs, sugars, and vanilla until pale and thick (2–3 min).
Slowly add melted chocolate and mix until smooth.
Sift in flour, cocoa, baking powder, salt, and espresso. Fold to combine.
Stir in chocolate chips.
Chill batter for 30–45 minutes.
Scoop dough onto lined baking sheets and bake at 350°F for 10–12 minutes.
Let cool on pan before transferring.
Chill longer for thicker cookies. Add sea salt on top before baking for contrast. Freeze extra dough for later.
