Preheat oven to 350 degrees. Spray two 8- or 9-inch round pans or one 13-by-9-by-2-inch sheet pan with vegetable pan spray.
In large bowl, combine cake mix, pudding mix, eggs, water and oil; beat at medium speed with electric mixer for 2 minutes.
Pour into prepared pans. Bake 30-35 minutes for round pans; 35-40 minutes for sheet pan, or until toothpick inserted in center comes out clean.
Cool in pans for 10 minutes; remove to cooling grid and cool completely. Divide cake in half; freeze one half for future use.
In large bowl, use hands to crumble cake until no large chunks remain. Add icing; mix with fingers until well combined. Form mixture into balls. Chill in refrigerator at least 2 hours.
Melt Candy Melts according to package directions. Dip sticks into melted Candy Melts and insert into cake balls; let set. Wait until candy is completely firm before dipping the pops completely in melted Candy Melts.
