In a small pitcher, mix 1/2 cup thawed orange juice concentrate, 1/2 cup Grand Marnier and 3 tbsp vanilla vodka. Stir to combine. Shave a cup of ice with the grater blade of a food processor (or a snow cone machine). Using an ice cream scoop, pack approximately 1 cup shaved ice into a paper snow-cone cup or cocktail glass. Drizzle the Creamsicle mix over the ice.
