Makes 2 ½ dozen
1 cup (2 sticks) unsalted margarine or butter, softened
1 1/4 cups granulated sugar
3/4 cup dark brown sugar
1 ounce unsweetened baking chocolate, melted
3 large eggs, at room temperature
2 1/2 cups all-purpose flour
1/2 cup unsweetened cocoa powder
1 1/4 teaspoons baking powder
1 1/4 teaspoons salt
1 tablespoon vanilla extract
1 1/2 cups chocolate chips
Preheat the oven to 350 degrees F. Line a large baking sheet with parchment paper.
In a stand mixer, beat the margarine/butter, sugar, brown sugar and chocolate until smooth. Add the eggs and mix until fully combined. Sift together the flour, cocoa powder, baking powder and salt in a bowl and add slowly to the batter until mixed. Add the vanilla and fold in the chocolate chips.
Drop by generous spoonfuls onto the prepared baking sheet, about 2 inches apart. Bake for 15 minutes. Transfer to a wire rack to cool.
