In a mixing bowl, whisk together the dry ingredients: flour, sugar, baking powder, and salt.

In another bowl, mix the wet ingredients: milk, egg, melted butter, and vanilla extract.

Pour the wet ingredients into the dry ingredients and stir until just combined. Do not overmix; a few lumps are okay.

Preheat a griddle or non-stick skillet over medium heat and lightly grease with butter.

Pour about 1/4 cup of batter onto the griddle for each pancake.

Cook until bubbles form on the surface, about 2-3 minutes, then flip and cook for another 2-3 minutes until golden brown.

Repeat with remaining batter, greasing the skillet as needed.

Serve warm with your favorite toppings such as maple syrup, fresh fruit, or whipped cream.
