Preheat an electric griddle to 350º Fahrenheit or start warming up a skillet over medium-low heat. Grease with butter and set aside.
In a large bowl, add your flour, baking powder, salt, and sugar and mix well.
In a smaller bowl, combine your beaten egg, milk, and melted butter. (See note below on optional ingredients.) Slowly add the wet ingredients to the dry ingredients.
Mix only until just combined. It's ok if there are a few clumps in the batter. The more you mix the batter, the flatter and denser the pancakes will be. This is one of the keys to having light and fluffy pancakes.
Working in batches, pour batter onto your preheated and oiled griddle or skillet. I like to use a 1/3-sized measuring cup. This will yield about 8 good-sized pancakes.
Allow the pancakes to cook for a few minutes. Once the edges start to set, it's time to flip. Carefully flip the pancakes using a large pancake turner.
Cook until golden brown. Do not flip more than once. (This is another trick to keep them light and fluffy.) Repeat with the additional batter. Top the warm pancakes with your favorite pancake toppings. Enjoy!
Notes
*If you want chocolate chip pancakes, add 1/2 tsp of vanilla and 1/4 cup of mini chocolate chips. Add this along with the wet ingredients before combining with the dry ingredients.
