Rub a lime wedge around the rims of two martini glasses.
Place the graham cracker crumbs in a small saucer. Dip the rims of the glasses in the crumbs to coat. Freeze for 5 to 10 minutes, while preparing the drink.
Combine the vodka, vanilla liqueur, lime juice, orange juice and coconut creamer in a cocktail shaker filled with ice (don't worry if the mixture looks curdled!). Cover and shake vigorously until well chilled, about 30 seconds. Strain into the chilled martini glasses and garnish with lime wedges. Serve immediately.
Coconut milk creamer comes in a variety of flavors (also, regular coffee creamer comes in coconut flavor!). Feel free to experiment and tailor to your taste buds.
