Add Homemade Starbucks Toasted White Chocolate Mocha Sauce (or equal amounts of Torani White Chocolate Sauce and the Torani Caramel 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 sauce until fully combined.
Next, pour in the milk, and fill the cup up with ice. Stir everything together to combine the flavors and chill the entire drink.
Top with whipped cream and red sprinkles, and enjoy your homemade Starbucks Iced Toasted White Mocha!
