If your mixture is a mess when you're trying to roll it into balls, put it in the refrigerator for 10 minutes or the freezer for about 3 minutes. This will help harden it up just enough so it's easier to work with. Make sure you don't leave it in the freezer for too long or you'll freeze it, and then you'll have the opposite problem.
Make this a fun activity for your kids! Depending on their age, assign them age-appropriate tasks. For example, younger kids can help measure out the ingredients, while older kids can stir the mixture and form the balls. Or even try making different shapes with the mixture!
Add decorations to make these for a special occasion! After drizzling the chocolate over the balls, you can add decorations like sprinkles or chopped nuts to make them look more festive.
