Line a baking sheet with parchment or wax paper, or a silpat baking sheet
Take one graham cracker square and spread marshmallow creme on top. Cover with a second graham cracker square. Repeat with all graham crackers. Place marshmallow-filled graham cracker squares on baking sheet.
Place in freezer for a few minutes so marshmallow fluff sets.
While in freezer, prepare melting chocolates. Set candy melts in microwave safe bowl and microwave in 30 second increments until melted. Stir in between each 30 second increment. Should only take 90 seconds - 2 1/2 minutes. Don't overheat.
Remove graham crackers from freezer.
Take each set and dredge in chocolate until covered. Place back on baking sheet.
Moving quickly, repeat with remaining graham crackers.
Once all are covered with chocolate top with sprinkles and decorations.
Chill to let set and eat!
