Begin by preparing and measuring all required ingredients to ensure a smooth cooking process.

In a large mixing bowl, sift together the all-purpose flour, baking powder, granulated sugar, and salt. Sifting helps to aerate the dry ingredients and promotes a uniform batter.

Create a well in the center of the dry mixture. Into this well, pour the milk, melted butter, and crack in the egg. Using a whisk or a large spoon, gently mix the wet and dry components together until a smooth batter forms. Take care not to overmix, as this may result in dense pancakes.

Preheat a nonstick skillet or griddle over medium-high heat. Lightly grease the surface with a small amount of oil or butter. Once the surface is hot, pour approximately ¼ cup of batter onto the skillet for each pancake.

Cook until bubbles begin to appear on the surface of the pancake and the edges start to dry, approximately 2 to 3 minutes. At that point, carefully flip the pancake using a spatula and cook the opposite side until golden brown.

Repeat the process with the remaining batter, greasing the pan as needed. Once all pancakes are cooked, serve immediately with toppings of choice, such as maple syrup, fresh fruit, or whipped cream.
