Preheat the oven to 350 degrees.
Combine the cake mix, eggs, and oil in a large mixing bowl and beat with an electric mixer at medium speed until well blended, about 2 minutes.
Form the dough into balls a little smaller than a golf ball size and place them 2 inches apart on 2 ungreased baking sheets.
Bake until very lightly browned at the edges, 10 to 12 minutes. Allow to cool completely before removing from the baking sheets.
