1/2 cup unsalted butter
12 ounces semi-sweet chocolate chips
1/2 cup granulated sugar
1/2 cup brown sugar, packed
2 large eggs
1 teaspoon vanilla extract
1 cup all-purpose flour
1/4 cup cocoa powder
1 teaspoon baking powder
1/2 teaspoon salt
Additional chocolate chips for filling
Directions:
Preheat oven to 350°F (177°C).
Melt butter and chocolate chips together; let cool slightly.
Whisk together sugars, eggs, and vanilla. Stir into the chocolate mixture.
Sift in flour, cocoa powder, baking powder, and salt; fold to combine.
Chill dough for 15 minutes for easier handling.
