Bake cake according to the directions on the back of the box. Allow to cool completely before starting to prep the rest of it.
Use a fork over the top to scrape and break it up into crumbs. Pour these from the pan into a large bowl. Scoop in 1/4 tub of frosting, incorporate, add another 1/4 until you use 3/4 of the tub creating a texture you are able to mold into balls with your hands.
Use your hands to create about 20 balls. Set on a baking sheet lined with parchment paper so they don't stick.
Melt a few of your candy melts in a bowl. Dip 1 stick into the melted chocolate and then stick 1 into each ball 3/4 of the way so they are all sticking up. When chocolate hardens it will help hold the cake pop ball on to the stick.
Place this tray into your freezer for 30 minutes so they can harden.
Melt the remaining candy chocolate melts in a bowl and dip each frozen ball into it to coat, set back on parchment baking sheet and sprinkle on sprinkles when wet if you like.
Set tray in your fridge for at least 10 minutes to harden the outside. Then serve. Keep leftovers on tray or in freezer bag in freezer or refrigerator.
