01 - Line a baking sheet with parchment paper to prevent sticking and ensure easy cleanup.
02 - Melt the semisweet or milk chocolate in a heatproof bowl set over simmering water (double boiler) or in the microwave in 30-second bursts, stirring until smooth and fully liquefied.
03 - Dip approximately two-thirds of each pretzel rod into the melted chocolate, using a spoon to help coat evenly if needed. Swirl gently to create tree-like branch patterns, then tap off any excess chocolate.
04 - Place the chocolate-dipped pretzels onto the prepared baking sheet, spacing them adequately apart to prevent touching during setting.
05 - While the chocolate remains wet, drizzle with melted white chocolate in zigzag patterns (if using), then immediately sprinkle with assorted sprinkles and position a candy star or pearl atop each tree.
06 - Allow the trees to set at room temperature for approximately 20 minutes, or refrigerate for 10 minutes until the chocolate completely hardens.
07 - Once fully set, carefully remove from parchment paper. Serve immediately or package individually in cellophane bags for gifts.
