Preheat the oven to 350 F. Place half of the pretzels onto a baking sheet and top each one with a chocolate peanut butter cup. Bake for 2-3 minutes.
Remove from the oven and sandwich with the remaining pretzels. Place chocolate chips in a microwave-safe bowl, and heat in the microwave in 30-second intervals, stirring well until it is fully melted and smooth.
Dip each pretzel bite in the chocolate and set onto a plate. Decorate with sprinkles. Let sit until it is fully set.
