Preheat the oven to 350 degrees Fahrenheit. Prepare the cake mix according to the package directions, and bake it in a 9x13 pan until a toothpick comes out clean.
Let the cake cool for 30 minutes.
Crumble the cake up in a bowl, then mix it up with the cup of frosting.
Form 1.5 Tablespoon sized balls with your hands (warning: your hands will get messy) rolling the dough between your hands.
Place the balls onto a cookie sheet lined with parchment paper.
Place the cookie sheet full of the cake balls in the fridge for 1 hour.
Add the candy melts to a medium microwave safe bowl and microwave them in 30 second increments, until you can stir them smooth.
Drop the cake balls into the melted candy in the bowl, use a spoon to cover them completely if needed.
Lift the cake ball out of the bowl with a fork, and tap the fork on the edge of the bowl to get the excess melted chocolate to drip off.
Place the cake ball onto a piece of parchment paper.
Top with sprinkles if desired.
Let the candy melt set until hardened, about 1 hour, then enjoy.
