Which ingredient is topped with chocolate drizzle in a Hot Double Chocolate Macchiato?

In a Hot Double Chocolate Macchiato, the ingredient typically topped with chocolate drizzle is chocolate milk. The drink itself is known for its rich, chocolatey flavor, which is complemented by the espresso. The addition of chocolate milk, rather than vanilla, is crucial in creating the double chocolate experience this beverage is named for.

The drizzle of chocolate on top offers a decadent appearance and reinforces the chocolate flavor that defines the beverage.
