Whisk together the dry ingredients: flour, baking powder, salt, and sugar.

In a separate bowl, mix the wet ingredients: milk, egg, and melted butter.

Pour the wet ingredients into the dry and stir until just combined; do not overmix.

Heat a lightly oiled griddle or frying pan over medium heat. Pour batter to form pancakes and cook until bubbles form, then flip and cook until golden.

Serve warm with your favorite toppings.
