Step 1: Prepare the Waffle Iron. Preheat your waffle iron according to the manufacturer's instructions. Lightly grease if needed.
Step 2: Mix the Dry Ingredients. In a large bowl, whisk together the flour, sugar, baking powder, baking soda, and salt until well combined.
Step 3: Combine the Wet Ingredients. In another bowl, whisk together the milk, melted butter, vanilla extract, and egg until smooth.
Step 4: Combine the Mixtures. Pour the wet ingredients into the dry ingredients and gently stir until just combined. Let the batter rest for 5 minutes.
Step 5: Cook the Paffles. Pour the appropriate amount of batter into the center of the iron and cook for about 3-5 minutes until golden brown.
Step 6: Serve and Enjoy. Carefully remove the Paffles and serve hot with your favorite toppings.
