Which drink includes a Skinny Cinnamon Dolce Latte?

The Skinny Cinnamon Dolce Latte is itself a unique drink that blends espresso with steamed nonfat milk and flavored syrup, specifically cinnamon dolce syrup, making it a light and flavorful option. Since the drink is based on espresso, the inclusion of espresso in its preparation is foundational.

The other choices do not align with the characteristics of a Skinny Cinnamon Dolce Latte. Black coffee, although it contains espresso, does not incorporate the additional flavors or steamed milk that define this particular drink. Mocha includes chocolate, which is not a component of the Skinny Cinnamon Dolce Latte. Chai Latte is an entirely different beverage that is based on spiced tea, again differing from the flavor profile and ingredients of the Skinny Cinnamon Dolce Latte. Hence, the correct answer highlights the essential ingredient that is central to the drink's identity.
