Preheat the oven to 350 F. In a large bowl, whisk together cake mix, eggs, and vegetable oil until smooth. Add in the green food coloring, and mix until it is fully green.
In a shallow dish, combine granulated sugar and ground cinnamon. Use a cookie scoop to form the cookie dough into balls, roll each one into the cinnamon sugar mixture.
Place the cookies onto a large ungreased baking sheet. Bake for 10-12 minutes.
