1In large bowl, stir together Bisquick mix, cocoa, egg and milk with whisk just until blended. Stir in chopped chocolate.
2Heat griddle or skillet over medium-high heat (375°F). Brush with vegetable oil if necessary (or spray with cooking spray before heating). For each pancake, pour about 1/4 cup batter (or desired amount) onto hot griddle. Cook about 3 minutes or until bubbles form on top. Turn; cook other side until set.
