Spread half the crackers with peanut butter and the other half with marshmallow creme. 

Place creme side down over peanut butter crackers, forming a sandwich. 

Melt chocolate candy coating according to package instructions. Dip cracker sandwiches into melted chocolate, allowing excess to drip off. Place onto waxed paper-lined baking sheets.

Decorate with additional melted chocolate and/or sprinkles. 

Let set and store in an airtight container.
