Heat stove-top griddle over medium high or electric griddle to 375ºF. Melt 1 tablespoon butter to coat grill surface. Pour ¼-cup batter onto griddle for each pancake and cook until bubbles begin to form on surface, 2 to 3 minutes. Flip pancakes and cook until golden, an additional 1 to 2 minutes. Add additional butter to griddle as necessary. To serve, top pancakes with sliced strawberries and syrup.
