Cook until surface of pancakes have some bubbles and a few have burst, 1 to 2 minutes. Flip carefully with a thin spatula, and cook until browned on the underside, 1 to 2 minutes more. Transfer to a baking sheet or platter; cover loosely with aluminum foil, and keep warm in oven. Continue with more oil and remaining batter. (You'll have 12 to 15 pancakes.) Serve warm, with desired toppings.
