Preheat the oven to 350 F. In a large bowl, mix together cake mix, eggs, and vegetable oil until smooth. Add in the green food coloring, mix until it is fully green.
In a shallow dish, combine granulated sugar and ground cinnamon. Roll the cookie dough into balls, and roll the cookies into the cinnamon sugar mixture. Place the cookies onto a large ungreased baking sheet at least 2-inches apart.
Bake for 10-12 minutes. Remove from the oven, and place candy eyes on each cookie.
