Gather all ingredients and measure them accurately.

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

In another bowl, combine milk, egg, and melted butter; whisk until smooth.

Pour wet ingredients into dry ingredients and stir gently until just combined (lumps are okay).

Preheat a non-stick skillet over medium heat; grease lightly with butter.

Pour about half a cup of batter onto the skillet for each pancake.

Cook until bubbles form on the surface (about 2 minutes), then flip and cook until golden brown (about 1 minute).

Serve warm with maple syrup or fresh fruit.
