Place chocolate chips and coconut oil in a microwave-safe bowl. Place the bowl in the microwave at 30 second intervals.
Stir chocolate in between each 30 seconds so all of the chips are just about melted. Continue to stir until the last remaining pieces have melted.
Use a fork to coat each pretzel in the melted chocolate mixture. Then tap it gently against the sides of the bowl until most of the excess chocolate has dripped off.
Use a second fork or a toothpick to slide each pretzel onto the lined baking sheet. Top each pretzel with sprinkles.
If you want to drizzle another layer or color of melted chocolate chips on top, scoop the melted chocolate into a quart size freezer re-sealable bag. Snip a very small corner of the bag to make a hole and squeeze the bag to drizzle the chocolate over the pretzels.
Refrigerate all the pretzels until the chocolate is hard, about 20 minutes. Remove from the pan and store in an air-tight container in the fridge for up to 10 days.
Notes
Storage: Store your dipped pretzels in an airtight container at room temperature for up to 2 weeks, or in the fridge for longer. Chocolate coated pretzels will last in the refrigerator for up to 3 months. Freezing: These chocolate covered pretzels freeze well. Place them in an airtight container and freeze for up to 4 months. To thaw, just let them sit out at room temperature for 30 minutes or so.
