What ingredient is used to top a Grande caffe vanilla frappuccino?

A Grande caffe vanilla frappuccino is typically topped with whipped cream, which adds a rich and creamy texture that complements the drink's flavors. Whipped cream is a signature topping for many frappuccinos at Starbucks, enhancing the indulgent experience and providing a delightful contrast to the cold blended beverage. The inclusion of whipped cream is particularly fitting for this drink, as it pairs well with the coffee and vanilla elements.

While various toppings like caramel drizzle or chocolate drizzle are popular for other beverages, they are not standard for the caffe vanilla frappuccino. Cinnamon might be a potential garnish for certain drinks, but it is not commonly associated with this specific frappuccino. Thus, whipped cream is the defining choice that aligns with the classic presentation of the Grande caffe vanilla frappuccino.
