Preheat the oven to 350 F. In a large bowl, mix together cake mix, eggs, and vegetable oil until smooth. Add in the food coloring, and mix until it is fully green. Fold in the chocolate chips.
In a shallow dish, combine granulated sugar and ground cinnamon. Roll the cookie dough into balls and roll each one in 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 top with heart sprinkles.
