Line a baking sheet with parchment paper or a silicone mat.
Place the white chocolate and coconut oil in a microwave-safe bowl. Microwave in 30-second intervals, stirring between each, until melted and smooth. If the chocolate is too thick, add more coconut oil.
Dip each pretzel halfway into the melted white chocolate, using a fork to tap off excess. For fully covered pretzels, dip completely and lift with a fork, tapping to remove excess.
Add your desired toppings while the chocolate is still wet.
Place the dipped pretzels on the prepared baking sheet, making sure they don't touch. Refrigerate for about 15 minutes or set at room temperature for about 30 minutes until the chocolate is set.
