To a blender, add Peppermint Syrup, Chocolate Sauce, whole milk, xanthan gum, instant coffee, and ice.
Blend the mixture until smooth (about 30-45 seconds).
Pour the blended Frappuccino mixture into a drinking cup, and top with whipped cream, chocolate shavings, and crushed peppermint candy (or your choice of toppings), and enjoy!
