Prepare cake according to package directions. Crumble into a bowl while still warm. If using day-old cake or cupcakes, pulse cake in food processor until it crumbles. Stir in frosting until well-mixed. Chill mixture for a couple of hours in the refrigerator.
Remove from refrigerator and, using a small scoop, form into balls. Push a skewer into each ball. Place on parchment paper and refrigerate for about an hour, or until firm.
Melt the chocolate in a double boiler or the microwave. Working in small batches, dip the cake pops in the melted chocolate and sprinkle with a little pink salt and decorating candy. Or, drizzle the cake ball with the white chocolate for decoration.
