Best Starbucks Oat Milk Drinks, Ranked In 2023 (Secret Menu)

Did you know that Starbucks offers delicious oat milk drinks? Whether you are vegan, vegetarian, lactose intolerant, lactose sensitive, following a healthy diet, or simply choose not to have dairy products, you don’t have to stop getting your favorite Starbucks drinks.

You can choose to substitute any drink at Starbucks with oat milk. Some of the best options are Iced Brown Sugar Oat Milk Shaken Espresso, Honey Oat Milk Latte, Iced Vanilla Latte with Oat Milk, Honey and Hazelnut Oat Latte, Oat Milk Chai Tea Latte, Iced Flat White with Oat Milk, and more. 

Not only does Starbucks offer countless oat milk options and alternatives, but they also have a secret menu which you can order from. Let’s take a deeper look into what that entails. 

What Types Of Starbucks Drinks Are Good With Oat Milk?

If you speak to anyone who orders oat milk drinks from Starbucks or check out Starbucks blog recommendations, the conclusion is vanilla-based drinks. Whether hot or cold, most Starbucks drinks that are favorites with oat milk options are vanilla-based. 

However, vanilla isn’t for everyone, and that’s okay! Oat milk is delicious with most drinks, including chocolate, hazelnut, Macha, and seasonal specialties. It will always be based on taste preference. Oat milk doesn’t have an overbearing flavor profile and thus blends well with any preferred drink. 

It is necessary to note that the vanilla preference could be related to the idea that many people who enjoy oat milk choose those types of drinks over chocolate and other flavors. How you take your coffee and what milk you add will always boil down to a person’s specific palate.
