In a large bowl, sift together the flour, baking powder, salt, and sugar. Sifting not only helps to combine the ingredients thoroughly but also aerates the flour, contributing to the fluffiness of the pancakes.
1 1/2 cup all-purpose flour, 3 1/2 tbsp baking powder, 1 tsp salt, 1 tbsp granulated sugar
In another bowl, beat the egg lightly with a whisk or fork. Then, add the milk, melted butter, and vanilla extract. Whisk everything together until it's nicely combined.
1 1/4 cups milk, 1 egg, 1 tsp vanilla extract
Pour the wet mixture into the bowl with the dry ingredients. Stir everything together until just combined. It's crucial not to overmix; a few lumps are perfectly fine and key to getting those fluffy pancakes we're aiming for.
Heat a lightly buttered griddle or frying pan over medium-high heat. The pan is ready when a few drops of water sprinkled on it dance and evaporate.
Pour or scoop the batter onto the griddle, using approximately 1/4 cup for each pancake. Wait until the pancake bubbles on the top and the edges start to look set, about 1-2 minutes, then flip it carefully with a spatula. Cook until both sides are golden brown, another 1-2 minutes on the second side. Adjust the heat as necessary; all stoves are a bit different.
Serve your fluffy pancakes hot off the griddle with your favorite toppings. Classic maple syrup, fresh berries, a dollop of whipped cream, or even a sprinkle of powdered sugar can make these pancakes a delightful treat.
