In a large mixing bowl, sift together flour, sugar, baking powder, and salt.
Whisk in milk, eggs, melted butter, and vanilla extract until well combined, but still a little lumpy.
Rest your batter for 5-10 minutes while you spray your pan with a non-stick spray on the side.
Heat the flat griddle or non-stick pan over medium-low heat and then melt a little butter to grease it.
Remaining lumps in the batter will start to soften as the moisture soaks in. Gently stir again.
Smoothly pour about 3 tbsp. of batter onto the griddle and let it spread out into a round pancake.
Allow the pancakes to cook until bubbles form and the edges are set before flipping with a spatula.
Cook other side until golden brown and then finish the remaining batter.
Plate and serve your pancakes with maple syrup or your choice of toppings.
