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 over medium-high heat. Once hot, grease 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 are defined and bubbles form. Flip the pancakes and cook for another minute. Remove them from the pan onto a plate and keep warm.

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