In a large mixing bowl, combine the dry ingredients: flour, sugar, baking powder, and salt. Whisk until well blended.

In a separate bowl, whisk together the wet ingredients: milk, melted butter, egg, and vanilla extract until smooth.

Pour the wet mixture into the dry ingredients and stir gently until just combined; some lumps are okay.

Preheat a nonstick skillet over medium heat for 3-5 minutes, lightly greased if necessary.

Scoop about ⅓ cup of batter onto the skillet and cook for 2-3 minutes until bubbles form and edges are set.

Flip the pancake and cook for an additional minute until golden brown. Repeat with remaining batter.

Serve immediately with your favorite toppings such as syrup, sauce, or fresh fruit.
