Preheat the oven to 375 degrees and line the baking sheets.In a large mixing bowl combine the cake mix, eggs, and oil. Stir until well combined. Add green food gel coloring.
When the cookies are done baking, remove them from the oven. Let sit on the baking sheet for 5 minutes and then remove and place on a wire rack to finish cooling.
Once the cookies are cooled, put a dot of cookie glue on the back of each red heart sprinkle and place a red heart sprinkle on the right side top of the cookie.
