01 - Line a baking sheet with parchment paper or wax paper.
02 - Place white chocolate or vanilla candy melts in a microwave-safe bowl. Heat at 50% power, stirring every 30 seconds until melted and smooth.
03 - Dip each pretzel rod about two-thirds of the way into the melted white chocolate, swirling gently for an even coating. Tap off any excess and arrange on the prepared baking sheet.
04 - Melt the red and blue candy melts separately in microwave-safe bowls, using the same method as the white chocolate.
05 - Using a spoon or a piping bag, drizzle the red and blue melted candy over the white chocolate-covered portion of each pretzel for a striped effect.
06 - While the coating is still wet, immediately top with red, white, and blue nonpareils or sprinkles.
07 - Allow pretzel rods to rest at room temperature until the coating is completely set, about 15 minutes. For faster results, refrigerate for 5 minutes.
08 - Once set, serve immediately or package the pretzel rods in cellophane bags for gifting.
