In a large bowl, sift together the flour, baking powder, salt, and sugar. Make a well in the middle and pour in the milk, egg, butter, and vanilla extract (if using). Break up the egg first with a fork, and then begin to combine the flour, working from the outside of the bowl in, until just combined and mostly smooth.

Heat a non-stick griddle or large pan over medium-high heat. Once hot, grease, spray, or melt butter on the hot surface. Pour ¼ cup of pancake batter onto the greased pan. Cook the pancakes for about 2 minutes, until the edges look defined and bubbles form. Flip and cook for another minute. Avoid pressing down on the pancake after flipping.

Plate a few pancakes on a plate, top with your favorite toppings and syrups.
