Add the Peppermint Syrup and White Chocolate Sauce to a cup, and brew 2 shots of espresso over the top. See my 5 Ways To Make Espresso blog post for various espresso making methods.
Stir together the espresso and sweeteners until fully combined.
Next, steam your milk using a steam wand, aerroccino, or warm milk in a pot or in the microwave, and froth with a handheld milk frother until foamy. Pour the steamed/frothed milk over the peppermint-chocolate-espresso mixture.
Top with whipped cream and your desired toppings: Crushed Candy Cane, Chocolate Shavings, Holiday Sprinkles, Chocolate Sauce Drizzle, or Cocoa Powder, and enjoy your homemade Hot Peppermint White Mocha!
