Blueberry banana oatmeal smoothies.

Your smoothie queen has returned with yet another delicious recipe to add to your morning routine! This Blueberry Banana Oatmeal Smoothie will quickly become your favorite. Why? Because adding oats seals the deal and makes the whole thing taste like pie. Not lying, it’s thick and creamy and tastes like blueberry pie. Yum!


  • Blueberries: Fresh or frozen, they are chock full of antioxidants and are sweet with just a bit of an acidic taste.
  • Banana: Creamy and sweet, bananas taste great with blueberries, and are a great way to naturally sweeten smoothies.
  • Oats: I usually use quick or old-fashioned/rolled oats, but you can use whatever you have on hand! Even steel-cut.
  • Yogurt: Plain yogurt contributes to the creamy texture while helping it blend. Use Greek yogurt for an extra protein punch.
  • Protein powder: I use vanilla flavor, but whether it’s whey or plant-based, it’ll help keep you full.
  • Flaxseed: Flavorless, but adds fiber and most importantly omega-3s.
  • Cinnamon: Adds sweet flavor and a load of antioxidants.
  • Nutmeg: Sweet, woody, nutty taste that contributes to the smoothie tasting like pie.

How to Make Blueberry Banana Oatmeal Smoothie

Liz adding blueberries to smoothie

Start your Blueberry Banana Oatmeal Smoothie by adding your blueberries to the bottom of your blender. I like using frozen so I don’t have to add ice.

And the flaxseeds, although you could also use flaxseed meal.

Frequently Asked Questions:

Can you put raw oats in a smoothie?

Yep! You don’t have to cook oats before adding them to your smoothie.

Do fruits lose nutrients when blended?

Nope! Unlike juicing, blending fruit into smoothies retains all of the nutrients, fiber, and flavor.

Can you make this smoothie ahead of time?

You can make the smoothie and freeze it, then move it to the fridge to thaw to a drinkable consistency when ready to drink, or follow my instructions on make-ahead smoothie freezer bags!

    Does the oatmeal get stuck in a straw? Or do you blend that first?

      I make this all the time, but instead of water I use unsweetened vanilla almond milk

    Found you via a “fell off the wagon” post on pinterest. So many great recipes here, I jumped right up to make this tasty smoothie. I have tons of wild alaskan blueberries we picked last fall and this certainly puts them to good use. I substituted almond milk for water, no ice since my berries were frozen and snuck in a handful of spinach too :) I had never tried oatmeal in a smoothie before, love it and the kids (age 6&7) do too.

        What would be a good substitution for yogurt?

          Oil :)

          Omit yogurt…this is like the smoothie I have been making for over 12 years! I use chia seeds in mine not flaxseed or yogurt

    Thanks for the recipe! May I ask what kind of protein powder you use? I worry it will make me “bulk up” which is the opposite of what I want to accomplish! :)
