In a large mixing bowl, crumble up funfetti cake until there are no big clumps. Add in frosting and heavy cream
Form 15 cake balls and place in the freezer for at least 30 minutes
Melt candy melts in a small bowl, according to the package directions. Remove cake pops from freezer. Dip one end of the lollipop stick into the melted candy melts and insert into the cake pop, continue until all cake pops have sticks in them. Dip the cake pop into the melted candy melts, rolling them around in the bowl until fully coated. Add sprinkles on top. The best way to allow them to dry is by sticking the lollipop stick into a thick piece of styrofoam or a floral foam block, so that they cake pops are standing upright. If you don’t have one of these look around and see what could secure your cake pop to dry without touching the countertop, get creative
Once candy coating is dry, place the cake pops in the refrigerator until ready to serve
