Microwave fluff with 1 tablespoon water for 20 seconds on high. Stir to combine and pour onto a shallow plate. Place crushed graham crackers on another shallow plate. Dip rim of each glass first in fluff and then in graham crumbs to coat. Drizzle chocolate in a circular motion inside each of the glasses.
Add all cocktail ingredients into cocktail shaker and fill with ice. Shake until cold then divide evenly between glasses. Place 2 marshmallows on a small skewer (to make 3 skewers total), then roast over open flame. Place on top of glasses and serve.
