Preheat oven to 350 degrees. Line two baking sheets with parchment paper and set aside.
In a large bowl, stir cake mix together with oil, vanilla, eggs, and chocolate chips. Refrigerate 30 minutes or until firm enough to roll and have the dough not stick to your hands.
Scoop dough into 24 even balls and roll in granulated sugar. Place onto prepared baking sheets and bake 8-10 minutes. Remove from oven and cool 4 minutes before removing to a cooling rack. Enjoy warm or at room temperature.
