Optional Chocolate Coating:
- Melt your white melting chocolate/wafers according to instructions. If using chocolate chips, add in a dash of heavy cream and heat it in the microwave in 15-30 second intervals stirring after each interval to avoid burning or seizing.
- If using sticks, dip the tip of your cake pop stick or popsicle stick into the melted chocolate and insert it halfway into the bar.
- Let dry for 2-3 minutes before fully dipping the bar or simply drizzle the white chocolate on top.
