Which drink is specifically sweetened with caramel?

The Caramel Macchiato is specifically sweetened with caramel, making it distinct among the options provided. This beverage typically combines espresso with steamed milk, vanilla syrup, and is finished with a drizzle of caramel sauce, which adds a rich, sweet flavor. The use of caramel is integral to the drink's identity, contributing not only to its sweetness but also to its visual appeal with the iconic caramel drizzle on top.

In contrast, the other drinks do not have caramel as a defining sweetener. The Latte Macchiato focuses more on the layering of milk and espresso without the sweetness of caramel. The White Chocolate Mocha is characterized by its use of white chocolate sauce instead of caramel, providing a different flavor profile. Lastly, the Espresso con Panna features espresso topped with whipped cream, typically with no added sweetness beyond that of the cream itself. Thus, the unique combination of ingredients in the Caramel Macchiato clearly identifies it as the choice that is specifically sweetened with caramel.
