Melt the chocolate in a microwave-safe bowl in 30-second intervals, stirring between each until smooth.
Dip each pretzel (both large and small) into the melted chocolate, coating evenly.
Assemble the bunny shape by placing a small pretzel on top of a large one, securing them with a dab of melted chocolate.
While the chocolate is still wet, decorate with mini M&Ms or candy pearls for the eyes and nose. Add sprinkles for extra fun.
If using, draw whiskers with an edible food marker or pipe them using icing.
Allow the pretzels to set at room temperature or place them in the refrigerator for faster hardening.
Once set, serve and enjoy!
