In a large mixing bowl, sift together the flour, baking powder, salt, and sugar until well blended.

Create a well in the center and pour in the milk, egg, melted butter, and vanilla extract. Mix gently until just combined.

Heat a non-stick griddle over medium-high heat for about 2 minutes, greasing lightly as needed.

Pour about 1/4 cup of batter onto the griddle for each pancake and cook until edges are set and bubbles form.

Flip each pancake carefully and cook for an additional minute until golden brown.

Serve immediately with your choice of toppings.
