Preheat the oven to 350 F. In a large bowl, mix cake mix with eggs and vegetable oil until smooth. Fold in the white chocolate chips.
In a shallow dish, combine granulated sugar and ground cinnamon. Use a cookie scoop to form the cookie dough into balls, and roll each one into the cinnamon sugar mixture.
Place the cookies onto a large ungreased baking sheet at least 2-inches apart. Bake for 10-12 minutes.
