1. Once your cake is cool, crumble it into small pieces. Stir in frosting and sprinkles. Place in the freezer for one hour.
2. Remove from freezer. Line a baking sheet with parchment paper (I didn’t big mistake!). Form into balls and place on the baking sheet. Return to freezer for at least 15 more minutes.
3. Melt chocolate in the microwave by cooking in 30 second intervals and stirring in between. Alternatively, heat on top of a double broiler.
4. With a spoon, carefully dip cake balls in the chocolate and return to baking sheet. Top with sprinkles and allow to harden in the refrigerator.
