01 - Line a baking sheet with parchment or wax paper.
02 - Place the chopped chocolate and coconut oil (if using) in a microwave-safe bowl. Microwave in 30-second intervals, stirring between each, until fully melted and smooth. Alternatively, melt chocolate in a heatproof bowl set over a saucepan of simmering water (double boiler).
03 - Dip each pretzel rod or mini pretzel into the melted chocolate, covering it about two-thirds of the way. Gently shake off excess chocolate.
04 - Immediately sprinkle with assorted sprinkles while the chocolate is still wet.
05 - Place the chocolate-covered pretzels on the prepared baking sheet. Let pretzels set at room temperature for about 30 minutes, or refrigerate for 10–15 minutes, until chocolate is firm.
