Gather and measure all ingredients.
In one bowl, mix flour, sugar, baking powder, and salt. In another bowl, whisk milk, egg, and melted butter until combined.
Make a well in the dry mixture and pour in the wet ingredients. Stir gently until just combined; lumps are okay.
Preheat a greased non-stick skillet over medium heat. Pour about half a cup of batter for each pancake.
Cook until bubbles form on top (about 2-3 minutes), then flip and cook until golden brown (another 2 minutes).
Serve warm with maple syrup or your favorite toppings.
