Preheat the oven to 350℉. Then line a large baking sheet with parchment paper or a silicone baking mat.
Whisk the eggs in a large bowl.
Add cake mix and vegetable oil. Then stir until combined.
Drop large spoonfuls of the cookie dough onto the prepared baking sheet. Make sure to space them at least 2 inches apart. You should have enough batter to make about 8 cookies.
Bake the cookies for 12 minutes. Then remove them from the oven and let them cool for 10 minutes to set. They will still be pale on top when you remove them from the oven.
Transfer your cookies to a serving dish and enjoy!
