In large bowl, combine flour, oats, baking powder and salt; mix well. In separate medium bowl, combine milk, egg and oil; blend well. Add liquid ingredients to dry ingredients all at once; stir just until dry ingredients are moistened (do not over mix). Add one of the stir-in options, if desired; mix gently. Heat skillet over medium-high heat (or preheat electric skillet or griddle to 375°F). Lightly grease skillet. For each pancake, pour 1/4 cup batter into hot skillet. Turn when tops are covered with bubbles and edges look cooked. Turn only once. Serve & enjoy!
