Preheat your waffle iron according to the manufacturer’s instructions.
Lightly grease the waffle iron with cooking spray or brush with melted butter.
Mix Dry Ingredients:
In a large bowl, whisk together the flour, sugar, baking powder, and salt.
Mix Wet Ingredients:
In a separate bowl, beat the eggs and then add the milk, oil (or melted butter), and vanilla extract. Whisk until well combined.
Combine Ingredients:
Pour the wet ingredients into the dry ingredients. Stir until just combined. The batter may be a bit lumpy, which is fine. Do not overmix.
Cook the Waffles:
Pour the batter onto the preheated waffle iron, using a ladle or measuring cup to distribute the batter evenly. Cook according to the waffle iron’s instructions, usually for about 4-5 minutes, until the waffles are golden brown and crisp.
Serve:
Serve the waffles hot with your favorite toppings such as maple syrup, fresh berries, whipped cream, butter, or any other preferred toppings.
