Looking for a fantastic non-dairy milk to use in smoothies? Try oat milk! Oat milk is one of our favorite vegan milk options. It’s seriously creamy and has the closest flavor to milk as any of the other plant-based milks (in our opinion). So what not try it in an Oat Milk Smoothie? This smoothie recipe is our favorite template and works using any type of frozen fruit. Here we’ve used strawberries: but feel free to get creative! Here’s a bit more about this tasty smoothie recipe.

Ingredients in this oat milk smoothie

This oat milk smoothie recipe works for any type of frozen fruit. But you can’t go wrong with strawberry banana! It’s our 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 our 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.

Why use oat milk 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.

Ways to add protein to this oat milk smoothie

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 powderProtein 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!

    Hello, I made a Oat Milk, strawberries and blueberries not sure why this happened but it so thick, can’t even use a straw to drink it ,what did I do wrong! Thanks

    1. Next time you can add more oat milk until it comes to a pourable consistency! I’ve added some clarifications in the recipe. Thanks for the note!

  2. Nora says:

    Great info and great recipe. I tried it with a very ripe banana, an apple and a cup of strawberries (slightly reduced quantities to fit inside my tiny blender) delicious! It didn’t really need it, but I added in a dash of vanilla extract and a teaspoon of honey, and it made it taste quite luxurious! definitely one I will repeat again and again I’m sure. I will try it with Chia seeds next for a bit of protein as you suggest. Thanks!

  3. Barrie says:

    Delicious!! I used Blueberries and Papaya. My bananas weren’t ripe, so I substituted Chick Peas (garbanzo beans) for the bananas. Added chia seeds and 1/3 scoop Orgain vanilla protein powder. NO honey or syup. Tastes great! A Keeper for sure!
    (P.S.> I’ve often substituted Chick Peas for bananas., I just drain and rinse well, then divide & freeze)

  4. Chandler Reeve says:

    THESE ARE FANTASTIC!! I made these smoothies by the recipe using room temperature bananas, frozen mixed fruit and honey. I added chia seeds for protein. They were initially very thick so I added oat milk until it was the texture I like. I made the recipe X2 and my grandson and I finished it all off in one sitting. Can’t wait to make more and experiment with different seasonal fruits.

    1. Alex Overhiser says:

      So glad you enjoyed!

  9. Barbara Burbine says:

    I love oatmilk. Been drinking it for a year.

  10. Jill Austin says:

    This recipe was tasty and made enough for about 4
    12oz smoothies, but after adding 2 room temp bananas and protein powder, it was not cold at all. I’m going to try it next time with frozen banana slices.
