Before you touch the chocolate, line a baking sheet with parchment paper and set it near your stove. Have your pretzels, sprinkles, and dipping tool ready to go, since chocolate can start to firm up quickly once it's melted.
Add your chocolate chips and oil to a microwave-safe bowl, then heat in 30-second bursts, stirring well after each one. This slow approach is the best way to make chocolate covered pretzels without scorching the chocolate.
Hold a pretzel rod by one end and dip the rest into the melted chocolate, turning it to coat evenly. Tap off the excess chocolate gently against the side of the bowl before setting it down.
While the chocolate is still wet, sprinkle on your sprinkles, crushed candy, or a pinch of sea salt. Work quickly here, since the coating firms up faster than you'd expect at room temperature.
Place each finished pretzel onto your lined baking sheet and let them sit at room temperature for about 30 minutes. Once the chocolate looks matte and firm to the touch, they're ready to enjoy or pack away.
