In large bowl, stir pancake ingredients with whisk until well blended.

Heat nonstick griddle or skillet over medium-high heat (375°F).

Brush griddle with vegetable oil if necessary (or spray with cooking spray before heating).

For each pancake, pour slightly less than ¼ cup batter onto hot griddle.

Cook until bubbles form on top and edges are dry.

Turn; cook other side until golden brown.

Drizzle pancakes with chocolate syrup; top with whipped cream, marshmallows and sprinkles.
