Calories in Starbucks Flat White come to 59 for the single Short size this drink is served in — a ristretto shot topped with steamed whole milk, made for a smaller, stronger cup than a regular latte.
Fat comes to 2.0g and protein to 4.2g, both driven almost entirely by the milk since the espresso itself contributes very little. Sugar sits at 5.1g, all lactose from the milk with nothing added.
For a bigger cup with a similar espresso-to-milk feel, a Cortado is the next size up, and lactose-free milk keeps the same calorie count here.
