Heat a nonstick griddle or nonstick skillet coated with cooking spray over medium heat. Spoon about 1/4 cup batter per pancake onto griddle. Turn pancakes over when tops are covered with bubbles and edges look cooked. Serve with syrup and butter.
For baby: Cut a pancake into bite-sized pieces and serve on a rimmed plate. Drizzle lightly with syrup.
Kitchen Tip: Keep cooked pancakes warm in a 200° oven while preparing remaining pancakes, and then serve to the whole family.
