What type of milk is used in a medium iced blackout?

The correct choice for the type of milk used in a medium iced blackout is chocolate milk. This drink features chocolate milk as a key ingredient, contributing to its rich and chocolaty flavor profile. In many coffee shops, including Black Rock Coffee Bar, chocolate milk is often used to enhance beverages that aim to deliver a sweeter, dessert-like experience.

Whole milk, almond milk, and skim milk may be used in other drinks, but they do not contribute the same chocolate richness that is signature to the iced blackout. This distinction is crucial as it helps in understanding not only the specific drink preparations but also how various types of milk can influence the overall texture and taste of coffee beverages.
