Line a large baking sheet with parchment or wax paper.
In a microwave-safe bowl, melt white chocolate in 30-second intervals, stirring between each interval until smooth.
Allow melted chocolate to cool for 5 minutes, but ensure it remains fluid.
In a large bowl, combine thawed Cool Whip and dry pudding mix until well blended.
Gradually fold the melted white chocolate into the Cool Whip mixture until completely incorporated.
Cover and refrigerate mixture for 30 minutes or until firm enough to scoop.
Using a small cookie scoop or spoon, form mixture into 1-inch balls.
Place formed candies on prepared baking sheet.
If using decorations, add them now before the candies set.
Refrigerate for at least 2 hours or until firm.
