Begin by gathering all your ingredients for the White Christmas Margarita. In a large shaker, combine 2 ounces of tequila, 4 ounces of white cranberry juice, 1 ounce of freshly squeezed lime juice, 1 ounce of Cointreau, 1 tablespoon of agave nectar, and 2 ounces of coconut cream. If you’re using coconut rum for an extra tropical twist, add that as well.
Once all the ingredients are in the shaker, seal it tightly and shake vigorously for about 15-20 seconds.
While your mixture is chilling, prepare the glass rims by mixing finely ground coconut flakes and coarse salt. Moisten the rim of each glass with a lime wedge, then dip into the coconut-salt mixture.
Fill each prepared glass with decorative ice cubes, then pour the margarita mixture over the ice-filled glasses.
Garnish each glass with a slice of lime and serve immediately.
