In a medium bowl, mix together the milk, pancake mix, egg and oil until it forms a thick batter. Preheat your waffle iron to the desired temperature according to manufacturer’s instructions.
Pour the batter onto the preheated waffle iron and spread it evenly across the cooking surface. Close the lid of the waffle maker and cook for 3-5 minutes or until golden brown.
Carefully remove the finished waffles from the waffle iron with a spatula and transfer them to a plate. Serve with butter and pancake syrup, or your favorite topping.
