Line a large baking sheet with parchment paper. Set aside.

You can melt it in a double boiler or use the microwave. If using the microwave: place the chocolate and oil in a medium heat-proof bowl. I recommend using a glass 2-cup liquid measuring cup because its depth makes dipping really easy. Microwave for 20-second increments, stirring after each, until chocolate is completely melted and smooth.

Dip a pretzel in the melted chocolate. Use a fork to lift it out, and tap the fork on the side of the bowl to allow excess chocolate to drip off. Use a toothpick to help slide the pretzel off the fork and onto the lined baking sheet. Top with sprinkles (if using) while the chocolate is still wet. If you have leftover melted chocolate, you can reheat it (if needed to keep it fluid) and drizzle it on top of the coated pretzels. I usually use a squeeze bottle for drizzling.

Refrigerate to set the chocolate, about 20–30 minutes. Once chocolate is set, store the chocolate-covered pretzels in an airtight container at room temperature for up to 1 week, or in the refrigerator for up to 2 weeks.
