Easy Oat Milk Smoothie Recipe (6 Delicious Flavors)

cups of oat milk smoothie

Oat milk and other dairy milk alternatives have become increasingly popular in America over the last few years. As a result, oat milk has quickly become one of the favorite milk options for vegans and those who have lactose intolerance.

Drinks made with oat milk have even found their way onto the Starbucks menu and have quickly become a fan favorite for coffee drinkers everywhere. This is largely thanks to the fact that oat milk is naturally sweet and much creamier than other milk alternatives.

These aspects also make oat milk an excellent liquid to add to smoothies. Oat milk smoothies are amazing, creamy, sweet, thick, and completely refreshing, especially if you’re looking for something to quench your thirst on a hot summer’s day. But, of course, it doesn’t hurt that oat milk is a safe choice for those who suffer from allergies or intolerances.

In this blog, we will give you our favorite recipe for an oat milk smoothie, as well as a few variations of what to put in it for you to try at home, so you too can enjoy the benefits of oat milk in a smoothie.

How to Store a Banana Oat Milk Smoothie

If you don’t drink all of your oat milk smoothie (regardless of the variety), you can store it in the fridge for up to 2 days. When you take the smoothie out of the fridge, make sure to stir it well to ensure the liquid hasn’t separated.
