Sift flour, baking powder, sugar, and salt together in a large bowl. Make a well in the center and add milk, melted butter, and egg; mix until smooth.
Heat a lightly oiled griddle or pan over medium-high heat. Pour or scoop the batter onto the griddle, using approximately ¼ cup for each pancake; cook until bubbles form and the edges are dry, about 2 to 3 minutes.
Flip and cook until browned on the other side. Repeat with remaining batter.
Serve and enjoy!
Notes
The salt amount has been reduced based on review feedback. The original recipe called for 1 teaspoon.
