Make the cake mix according to the package instructions. Let cool - I let mine cool overnight.
Crumble the cake into a large mixing bowl. Mix the cake crumbles with the icing until completely incorporated. Place into the refridgerator for 30 minutes to an hour.
Roll cake mixture into balls - I used a small cookie scoop to get my balls to be roughly the same size. Place on a cookie sheet - once all the balls are formed - place in the freezer for another 30 minutes to an hour.
Melt the white melting chocolate - put all the pieces into a medium bowl, and heat in the microwave. I melt my chocolate for a minute and a half, stir, and then continue heating in 30 second increments until completely smooth.
Dip the cake balls into the chocolate and completely coat them. Lay them on a piece of wax paper until cooled and completely hardened.
Note - these can be made in any variation you like - you could do carrot cake balls, chocolate cake balls, funfeti cake balls... the sky is the limit!
