Creating fluffy pancakes is simple when you follow these steps:

1. Mix Dry Ingredients: In a large bowl, whisk together the flour, sugar, baking powder, and salt until well combined.
2. Combine Wet Ingredients: In another bowl, whisk together the milk, egg, melted butter, and vanilla extract, if using.
3. Combine Mixtures: Pour the wet ingredients into the dry ingredients. Stir gently until just combined. Be careful not to overmix—some lumps are okay!
4. Preheat Skillet: Heat a non-stick skillet or griddle over medium heat. Lightly grease the surface with cooking spray or butter.
5. Pour Batter: Using a ladle or measuring cup, pour about ¼ cup of batter onto the skillet for each pancake.
6. Cook Pancakes: Cook for 2-3 minutes or until bubbles form on the surface and the edges look set. Flip and cook for an additional 1-2 minutes until golden brown.
7. Repeat: Continue cooking the remaining batter, adding more butter or cooking spray to the skillet as needed.
8. Serve Warm: Stack the pancakes on a plate and keep them warm while you finish cooking the rest.

These steps will guide you in creating incredibly fluffy pancakes that everyone will enjoy.
