Bring a saute pan or griddle to a medium temperature. Cook the pancakes, utilizing a quarter-cup scoop, for three to four minutes, or until bubbles appear on the surface, over a heated griddle. Cook for an additional 1 to 2 minutes, turning once, or until thoroughly cooked.
Warm before topping with butter and maple syrup.
