Preheat your oven to 350°F and spray a 13 x 9 pan with vegetable pan spray to prevent sticking.
In a large bowl, combine the cake mix, pudding mix, eggs, water, and oil. Beat at medium speed for about 2 minutes until well-blended, then pour the mixture into the prepared pan.
Bake in the preheated oven for 30-40 minutes or until a toothpick inserted in the center comes out clean. Cool in the pan for about 10 minutes before transferring it to a wire rack.
Once the cake has cooled completely, crumble it into fine pieces using your hands or two forks until no large chunks remain.
Add frosting to the crumbled cake and mix thoroughly with your fingers until fully combined into a dough-like consistency.
Form the mixture into small balls and chill them in the refrigerator for at least two hours to let them harden before dipping them in melted Candy Melts.
