Line a baking sheet or a pan with parchment paper. Using a sharp knife, finely chop the white chocolate.
Place chocolate in a microwave-safe bowl. Heat chocolate in 30-second intervals, stirring between each, until melted and smooth.
Spread chocolate into an even layer on the prepared pan. Evenly distribute the chocolate coins on the melted chocolate.
Top with sprinkles.
Refrigerate for 30 minutes or let it cool at room temperature or until hardened.
Once completely set, remove the parchment paper and break the bark into pieces.
Optional: Carefully slide 3-5 chocolate barks into an individual cellophane bag. Use a twist tie or ribbon to seal the bag.
