Preheat the oven to 350 F. Line a 12 cup muffin pan with paper liners. In a large bowl, mix together cake mix, eggs, and vegetable oil until smooth. Fold in the white chocolate chips.
In a shallow dish, combine granulated sugar and ground cinnamon. Roll the cookie dough into balls, and roll each one into the cinnamon sugar mixture. Place the cookies into the prepared muffin pan. Bake for 12-15 minutes.
