In a bowl, combine eggs, oil, and cake mix. Mix well. Refrigerate batter for 30 minutes.
Meanwhile, preheat oven to 350°F. Line a baking sheet with parchment paper.
Roll batter into balls and flatten slightly with the palms of your hand. Add sprinkles or confetti if desired (some mixes come with it). Bake for 8-9 minutes. Let cool for 3 minutes. Enjoy!
