Melt candy melts in microwave as directed on package.
Pour enough melted chocolate into silicone or plastic candy molds (or paper mini muffin liners) to cover the bottom of the mold. Reserve remaining melted chocolate.
Use a small never-used paintbrush to gently brush the melted chocolate up the sides of the molds; once lined with chocolate, refrigerate molds while you prepare the filling.
Prepare Chocolate Peanut Butter Cheese Ball Mix as directed on package using softened cream cheese and creamy peanut butter. Mix well to ensure a soft, creamy consistency.
Remove chocolate molds from refrigerator. Using a spoon or piping bag, gently fill molds ¾ full with the cheese ball mixture. Pour remaining melted chocolate over the cheese ball mixture to seal the filled candy. Refrigerate candies until ready to serve.
