Combine your cake mix, eggs and oil into a mixing bowl.
Once combined, roll into tablespoon sized balls and drop onto a baking sheet, you'll have about a dozen cookie balls. I use a piece of parchment paper for less cleanup.
Bake for 7-9 minutes. They will finish baking on the sheet a bit, you want to remove them from the oven when the top is cracking and you're just starting to see the bottom of the cookie turn golden.
Allow to cool, then top with frosting and sprinkles.
