Line a baking tray with wax paper. Use a melon baller as a scooper to form balls with the cake mixture. Place on wax paper. Once you have used all of the cake mixture, place the baking tray in the freezer for 1 hour.
Remove the balls from the freezer. Using one toothpick, pick up the balls one at a time and dip in the chocolate. Use a second toothpick to slide the ball off the first toothpick onto the wax paper lined baking tray. NOTE: We found that an old Easter egg dipper works as well. If the balls fall off the toothpick into the chocolate, they are not firm enough to work with and you'll need to place them back in the freezer for additional time.
