Preheat oven to 350 degrees F°. In a large bowl, mix together the cake mix, eggs, and vegetable oil. It will form a thick dough. Roll dough into 2 inch balls and place onto an un-greased cookie sheet. Gently press down on dough to flatten slightly. Bake for 8 to 9 minutes. (They wont seem done, but they are!) Remove from oven and let completely cool on the cookie sheet.
