Preheat the waffle maker according to the manufacturer's instructions.

In a large mixing bowl, whisk together the flour, baking powder, sugar, and salt.

In another bowl, beat the eggs, then add the milk, vegetable oil, and vanilla extract.

Pour the wet mixture into the dry ingredients and stir gently until just combined.

Lightly grease the waffle maker with cooking spray or a bit of oil.

Pour batter into the preheated waffle maker and close the lid, cooking according to manufacturer's timing, usually 3-5 minutes.

Check for doneness; waffles are ready when golden brown and crisp.

Carefully remove the waffle and serve hot with toppings.
