Final answer:
An Iced Brown Sugar Oat Shaken Espresso is made by shaking espresso with brown sugar and cinnamon, pouring it over ice, and then topping it with oat milk. The queried Viennese coffee with whipped cream and separate brown sugar is quite different from this drink.
Step-by-step explanation:
The student has asked about how to make an Iced Brown Sugar Oat Shaken Espresso, which seems to be a mix-up with another drink: a Viennese specialty described as a strong black coffee, served in a glass and topped with whipped cream, with powdered brown sugar served separately. However, the Iced Brown Sugar Oat Shaken Espresso is a different beverage, and it typically involves the following steps:
- Brewing a shot or two of espresso.
- Shaking the espresso with brown sugar and cinnamon (to create the flavor base).
- Filling a glass with ice, and pouring the shaken espresso over it.
- Topping the drink with oat milk and possibly a sprinkle of brown sugar for aesthetic and flavor.
- This drink is a popular offering at many coffee shops and can vary in preparation and presentation, but the key ingredients remain espresso, brown sugar, oat milk, and ice.
