To make a 16 ounce (grande) Starbucks drink, you’ll need 2 Nespresso espresso or ristretto capsules. You can also use 1 Vertuo double espresso.
With the Vertuo machine capsules, only use espresso capsules and not the coffee capsules that make 7.77 ounces.
Starbucks uses 2% milk to make their Iced White Mochas, but you can use any milk you like.
Instant coffee can be used if you don't have espresso. Combine 1 tablespoon of instant coffee and ¼ cup hot water to replace the 2 shots of espresso in the recipe.
If you don't have white chocolate sauce, replace it with sweetened condensed milk.
The whipped cream is flavored with vanilla but if you don't have vanilla syrup, you can sweeten the heavy cream with 2 teaspoons of sugar.
