In a mixing bowl, combine Yellow Cake Mix (2 cup), Milk (1 cup), Egg (2), and Butter (2 tablespoon) by hand. Stir until just blended.
Gently fold in the Sprinkles (1/3 cup).
Heat a waffle iron. Spray with butter flavored non stick spray. Fill waffle iron about 2/3 full. The amount will depend on the size of your waffle iron.
Close waffle iron and cook until the cake is cooked through and outside is golden brown. Serve with Maple Syrup (to taste) and enjoy!
