This Blueberry Banana Oat Smoothie is thick, creamy, and naturally sweet. A plant-based breakfast that tastes like a treat but is packed with nourishing ingredients. A quick 5-minute recipe the whole family will love.

If you’re on a smoothie kick, you’ll also enjoy my dairy free blueberry smoothie, acai banana smoothie, or this orange creamsicle smoothie recipe.

Blueberry Oat Smoothie

When my kids were little, I was always looking for ways to get more nutrients into their day, but it had to be something they’d actually enjoy.

At first, I made the smoothies a little sweeter so they’d be excited to drink them. Over time, their taste buds adjusted, and smoothies became a breakfast they looked forward to.

We rotated between simple green smoothies, fruit blends like this sweet strawberry smoothie recipe, or this acai smoothie recipe. This blueberry oat smoothie is still a tried and true favorite we come back to again and again.

In the Kitchen Tips

  • Pre-freeze bananas: Having frozen bananas on hand will make your smoothies creamy every time.
  • Fresh fruit or bananas: Add a cup or two of ice if you’re using fresh blueberries or bananas.
  • Milk options: Use oat, almond, soy, or cashew milk, or try my homemade cashew nut milk.

Blueberry Banana Oat Smoothie FAQs

Can you use fresh blueberries in a blueberry oat smoothie?

Absolutely, though you may need to add a cup or two of ice to achieve the same creaminess.

Which type of milk is best for blueberry oat smoothies?

Almond milk gives this blueberry oat smoothie its subtle nutty undertone, but any plant-based milk will work.

What can I use instead of Medjool dates in this blueberry oat smoothie?

Any date will work, or you can use a touch of maple syrup or agave nectar.

Equipment

  • High-speed blender

Ingredients
  

  • 2 cups frozen blueberries
  • 1-1/2 cups unsweetened plant-based milk
  • 2 frozen bananas
  • 1-2 Medjool dates, depending on sweetness preference
  • ½ teaspoon cinnamon
  • ¼ cup oats

Instructions
 

  • Combine all ingredients in a high-speed blender
  • Blend until smooth and creamy
  • Enjoy!

Notes

  1. Frozen bananas add lots of creaminess to a smoothie, so I always have them on hand. If you’re using fresh blueberries or bananas, add a cup or two of ice.
  2. Sweetener swap: If you don’t have Medjool dates, you can use maple syrup, agave nectar, or your favorite sweetener. Adjust to taste depending on how sweet your fruit is.

    I’ve made this smoothie for years, and it never gets old. The oats make it creamy and filling, and I love how quick it is for busy mornings. Sometimes I swap the dates for a drizzle of maple syrup — both work great!
