Begin with two small plates. To one, add a teaspoon of honey. To the other, add the sweetened coconut. (I recommend giving the coconut a rough chop before using.) Rim the edge of the martini glass first in the honey and then in the coconut. Set aside.
In a cocktail shaker filled with ice, combine the whipped vodka, coconut rum, half and half, cream of coconut, and pineapple juice.
Shake vigorously; then strain into your prepared martini glass.
As a final garnish, cut a small slit in a marshmallow and hang it on the edge of the glass.
