In a large mixing bowl add cake mix, eggs, vanilla, and oil.

Beat on medium speed until smooth.

Pour in sprinkles and fold in with a spatula.

Cover the dough and place in the fridge for at least 30 minutes {up to overnight}.

Preheat oven to 350 degrees.

Remove from fridge and using a medium sized ice cream scoop form dough into medium size balls and place in rows on a lined baking sheet.

Bake for 10-12 minutes. They will still be soft and light colored.

Remove from oven and let  cool on the cookie sheet before removing to a plate to serve or wrap up.
