Spread half of the crackers with peanut butter. Spread remaining crackers with marshmallow creme; place creme side down over peanut butter crackers, forming a sandwich.
Dip sandwiches in melted candy coating, allowing excess to drip off. Place on waxed paper-lined pans; refrigerate for 15 minutes or until set. If desired, drizzle with additional candy coating and decorate with sprinkles. Store in an airtight container.
