1Heat griddle or skillet over medium-high heat; spray with cooking spray. In medium bowl, stir together all ingredients except hazelnut spread until blended.
2For each pancake, pour scant 1/4 cup batter onto hot griddle. Add 1/2 teaspoon hazelnut spread to center of batter; cover with a small amount of batter. Cook until edge is dry and bubbles form on top of pancake. Turn; cook until golden brown. Serve with butter and warm maple syrup.
