Heat a griddle or skillet on medium for at least 5 minutes.
Mix together milk and oats; add oil, eggs, and beat thoroughly. Using a fork, stir in pancake mix and brown sugar. Do not overbeat; stir just until dry ingredients become moist.
Grease surface of griddle or skillet very lightly. Using a ladle, pour out about ¼ c. of batter onto hot surface. Turn each cake over as soon as top begins to bubble. Cook second side until it, too, has browned.
Serve with local butter and maple syrup or a smear of your favorite jam.
