Spread 1 tsp. peanut butter on each of 24 of the crackers.
Spread 1 tsp. marshmallow cream on each of the remaining 24 crackers. Cover each peanut butter-topped cracker with one marshmallow-topped cracker, marshmallow-side down, to make sandwich.
Dip sandwiches halfway into melted chocolate, then in coconut.
Place on large sheet of waxed paper; let stand until chocolate is firm.
Store in airtight container at room temperature for up to 1 week.
