In a mixing bowl, whisk together the flour, sugar, baking powder, and salt.

In another bowl, combine the milk, egg, and melted butter.

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

Heat a griddle or frying pan over medium heat and lightly grease it with butter or oil.

Pour 1/4 cup of batter onto the griddle for each pancake.

Cook until bubbles form on the surface, about 2-3 minutes, then flip and cook for another 2-3 minutes until golden brown.

Serve warm with your favorite toppings such as syrup, fruit, or whipped cream.
