Gather all ingredients.
Sift together flour, baking powder, sugar, and salt in a large bowl. Whisk in milk, melted butter, and egg until combined. Let batter rest for 5 minutes. Preheat a large skillet over medium-high heat. Spray with cooking spray.
Pour batter into the hot skillet, about ¼ cup batter for each pancake. Cook until bubbles appear on the sides and center of each pancake, 2 to 3 minutes.
Flip and cook until the bottom is golden, 1 to 2 minutes.
Serve with butter and maple syrup and enjoy!
