Calories in Starbucks Oat Milk Latte (Hot) come to 226 in the only size this drink is offered in, Tall. This latte swaps in oat milk for a creamy, plant-based alternative to dairy.
That single Tall serving carries 12.5g of fat and 4g of protein, with oat milk giving it a naturally sweet, slightly nutty flavor compared to a dairy-based latte, along with a noticeably lower protein count.
This pairs well with the iced version if you’re deciding between a warm or refreshing dairy-free latte.
