Begin by preheating the waffle iron according to manufacturer's instructions.
In a mixing beat the egg and sugar for a minute or a two.
Add vegetable oil, milk and vanilla whisk to combine.
In another mixing bowl, whisk together the all-purpose flour, baking powder, and salt.
Combine the wet and dry ingredients together until just combined. It's important not to overmix; a few lumps are perfectly fine.
Lightly grease the waffle iron with a non-stick cooking spray or a small amount of melted butter. Pour the batter onto the preheated waffle iron, using a ladle or a measuring cup. Be mindful not to overfill, as the batter might spread and make a mess.
Close the waffle iron and cook according to the manufacturer's instructions. Typically, it takes about 3-5 minutes for the waffles to become golden-brown and crispy.
Serve warm with maple syrup or honey.
