Using a hand mixer or whisk, mix together the box cake mix with the vegetable oil, milk, and eggs.
Heat a waffle maker to medium-high heat. When the waffle maker is hot, add ¾ cup of the batter and cook for 3-4 minutes. Remove the waffle and repeat with the rest of the batter. Serve hot with your favorite toppings.
