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

In a separate bowl, combine the egg, milk, and melted butter, then mix well.

Pour the wet ingredients into the dry ingredients and stir until just combined; a few lumps are acceptable.

Heat a lightly oiled griddle or frying pan over medium-high heat.

Spoon about 1/4 cup of batter per pancake onto the hot griddle.

Cook each side for 2-3 minutes until golden brown and fully cooked.

Serve the pancakes immediately with your preferred toppings.
