Preheat the oven to 350 F. In a large bowl, mix together cake mix, eggs, and vegetable oil until smooth. Fold in the butterscotch baking chips.
In a shallow dish, place the powdered sugar. Roll the cookie dough into balls, then roll each one into the powdered sugar. Place the cookies onto a large ungreased baking sheet at least 2-inches apart. Bake for 10-12 minutes.
