Oat milk is one of my favorite vegan milk options as a non-dairy base for smoothies and drinks. It’s seriously creamy and has the closest flavor to milk as any of the other plant-based milks (in my opinion!).

So what not try it in an oat milk smoothie? This smoothie recipe is my favorite template and works using any type of frozen fruit. Strawberry banana is my personal favorite, but mango, peach, or a mixed berry blend are all delicious here too.

What You’ll Need

This oat milk smoothie recipe works for any type of frozen fruit. But you can’t go wrong with strawberry banana! It’s my favorite way to load up on healthy fruit that tastes like a dessert. Here are the ingredients you’ll need:

  • Frozen strawberries (or any frozen fruit): Strawberries are my go-to, but there are many more ways to mix and match this recipe.
  • Fresh banana: All you need are two room temperature bananas. No need to remember to freeze them!
  • Oat milk (plain unflavored): Use plain or unflavored oat milk. You can use vanilla if you like, but sometimes vanilla flavors are overly sweet or artificial tasting.
  • Ice: Ice adds just the right frozen texture.
  • Maple syrup or honey (optional): Whether you need it depends on the ripeness of the bananas. Sometimes frozen strawberries can also be very tart and need a little sweetener. Add a touch to taste.

  • Blueberries, raspberries, or mixed berries
  • Mango
  • Peach
  • Pineapple
  • Blueberry mango
  • Raspberry peach
  • Mango pineapple

Why Oat Milk Works So Well in Smoothies

Oat milk is a dairy free, plant based milk that’s made with oats and water. It’s fantastic for smoothies because it’s a dairy free milk that helps to achieve a creamy texture. Side note: it’s also great for vegan lattes! It’s one of the only vegan milks that froth up like dairy milk. Here’s what to know about using oat milk in smoothies:

  • Can you taste oat milk in smoothies? Not really! Oat milk has a similar flavor to dairy milk, and melds well into flavors.
  • Does oat milk make smoothies thicker? Again, not really. But one thing to note: oat milk is closer in creamy texture to dairy milk than almond milk, which is more like water. So it’s a very good substitute for dairy milk.

How to Add Protein

This oat milk smoothie is vegan, so it doesn’t have any dairy milk or yogurt like our standard smoothie recipes. Here’s the thing: both of those ingredients have a good amount of protein. So if you’re looking for a protein-packed drink, you’ll want to add one of the following:

  • Almond butter: Add 1 tablespoon of almond butter, or use 2 tablespoons for an even nuttier flavor. It does add an almond flavor and will dull the color of the smoothie a bit.
  • Protein powder: Protein powder is another plant-based way to amp up the protein in this smoothie. Use a high quality vanilla protein powder (some notes on buying a good brand are in this energy balls post).
  • Chia seeds: Add 2 tablespoons of chia seeds to this smoothie to add 11 grams fiber and 4 grams protein!

Pro Tips for the Best Oat Milk Smoothie

  • Add liquids first, and start with less oat milk. Begin with ¾ cup and add more only if the blender needs it. Too much liquid will thin out the texture.
  • Stop and scrape down the sides. Thick smoothies like this one tend to get stuck: stopping once or twice to scrape everything toward the blade makes a big difference.
  • Taste before serving. Depending on the sweetness of your fruit, you may want to adjust with a little maple syrup at the end.

How to Store

This smoothie is best served immediately, but it stores reasonably well if you want to make it ahead. Pour any leftovers into a sealed jar and refrigerate for up to 1 day. Give it a stir or a shake before drinking since it will separate slightly as it sits.
