This healthy blueberry oat smoothie tastes like a blueberry muffin in a glass thanks to the combination of blueberry, oats, and vanilla. You’ll be sure to fall in love with this dairy free smoothie!
I love a warm bowl of healthy blueberry oatmeal on a cold day but sometimes I need to switch up my breakfast routine a little. It hadn’t occurred to me until recently that you could add oats to a smoothie, but it totally works! You get the same health benefits from the oats without the cooking time.
This blueberry oat smoothie is just one of many delicious smoothie recipes on the blog – here are a few more of my favorites: blueberry cashew smoothie, lemon raspberry smoothie, pear green smoothie.
Why You’ll Love this Recipe
- Packed with Antioxidants: This smoothie is a delicious and antioxidant packed way to start your day or sip on as a post workout snack.
- Great Source of Fiber: Fiber is an important nutrient that too many are missing out on – adding oats to a smoothie like this one is a great way to sneak extra fiber into your day.
- Restriction Friendly: This smoothie is vegan, dairy free, and gluten free (if using gluten free oats).
Ingredients You’ll Need

- Frozen Blueberries: For the best flavor, I like using frozen wild blueberries. They are smaller in size than traditional blueberries and have a much more intense blueberry flavor.
- Old Fashioned Oats: You’ll want to use either old fashioned or quick cooking oats for this smoothie. Do not use steel cut oats as these will not blend well.
- Yogurt: Use your favorite plain or vanilla flavored yogurt for this smoothie. For a vegan/dairy free option, I use the unsweetened vanilla yogurt from Kite Hill.
- Milk: use any milk that you prefer. My favorite is unsweetened, plain soy milk since it is much higher in protein than other plant-based milks like almond milk.

Flavor Boosters:
- Lemon Zest: Add a little bit of lemon zest before blending for a pop of bright lemon flavor. I love lemon in smoothies like this one and my raspberry lemon smoothie.
- Cinnamon: Add 1 teaspoon ground cinnamon before blending. The cinnamon pairs well with the blueberries and vanilla.
- Almond Extract: Makes this smoothie taste just like a blueberry muffin! Add 1/2 teaspoon vanilla extract before blending.
- Vanilla Protein Powder: For extra protein and vanilla flavor, add a scoop of your favorite vanilla protein powder to this smoothie before blending.
- Spinach: Ok- not a flavor booster, but a great way to include an extra serving of veggies. I usually add 1 generous handful of fresh baby spinach to my smoothies. (Although, adding greens will change the color of the finished smoothie.)
Step by Step

Step One: Add all of your ingredients to a blender. (You can also blend the oats until finely ground first and then add the rest of the ingredients if you find they aren’t pureeing smooth.)

Step Two: Puree until smooth. Add more liquid if needed when blending. Pour into two glasses to serve.
Expert Tips
- Use frozen fruit: For a thicker, frozen smoothie use frozen fruit. Adding ice to smoothies can thicken them but can also water them down so I prefer to use frozen fruit.
- Start on low speed: For best results, start by pureeing on a low speed and then gradually increase the blender speed.
- Add more liquid if needed: Depending on what type of blender you are using, you may need to add more liquid – especially if using both frozen blueberries and banana.
- Add sweetness: Feel free to add more sweetness to your smoothie by adding some medjool dates, maple syrup, or honey.

Recipe FAQs
You can use an extra 1/2 cup of yogurt, 1/2 avocado, or 1 cup frozen cauliflower rice instead. Since these options aren’t as sweet as a banana, you may want to add a little maple syrup or a date to your smoothie before blending for extra sweetness.
Nope! Blending up your blueberries into a smoothie does not change the nutrient composition. You will get all the same nutrient benefits from whole blueberries or pureed blueberries.
