01 - Line a baking sheet with parchment paper or wax paper to prevent sticking.
02 - Place white chocolate or vanilla candy melts in a microwave-safe bowl. Microwave at 50% power, stirring every 30 seconds, until smoothly melted.
03 - Dip each pretzel rod two-thirds of the way into the melted white chocolate, swirling gently for even coverage. Allow excess to drip off, then place on the prepared baking sheet.
04 - Place red and blue candy melts into separate microwave-safe bowls. Melt each color at 50% power, stirring every 30 seconds, until smooth.
05 - Use a spoon or piping bag to drizzle red and blue melted candy over the white chocolate-dipped areas for a festive striped effect.
06 - Immediately sprinkle red, white, and blue nonpareils or star-shaped sprinkles onto the coated pretzels before the chocolate sets.
07 - Let pretzel rods sit at room temperature until chocolate is fully set, about 15 minutes. Refrigerate for 5 minutes to speed up the setting process, if desired.
08 - Serve immediately, or package the decorated pretzel rods in cellophane bags for gifting or parties.
