Preheat oven to 200 degrees. Gather ingredients and have a baking sheet or heatproof platter ready to keep cooked pancakes warm in the oven.

In a small bowl, whisk together flour, sugar, baking powder, and salt; set aside.

In a medium bowl, whisk together milk, butter (or oil), and egg. Add dry ingredients to milk mixture; whisk until just moistened (do not overmix; a few small lumps are fine).

Heat a large skillet (nonstick or cast-iron) or griddle over medium. Fold a sheet of paper towel in half, and moisten with oil; carefully rub skillet with oiled paper towel.

For each pancake, spoon 2 to 3 tablespoons of batter onto skillet, using the back of the spoon to spread batter into a round (you should be able to fit 2 to 3 in a large skillet).

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.
