Our Favorite Oatmeal Smoothie Recipe

We love smoothies at my house! Even throughout the winter my kiddos and I will drink smoothies for breakfasts or snacks. Since we have them so often for breakfast, I like to make sure they’re satiating. That way, I’m not making a second breakfast of Blueberry Pancakes twenty minutes after the boys have slurped down their smoothies.

One of my favorite ways to make a smoothie more filling is adding a nut butter — you’ll find almond butter added to this Cherry Smoothie and Banana Smoothie — both are so filling. And the other thing I’ve recently started adding? Oats! Oatmeal not only adds fiber, protein, and antioxidants, but it also makes sure the smoothie is satisfying.

Can you put oatmeal in a smoothie?

Absolutely, it’s completely safe to add raw, and once you try it, you’ll realize that oatmeal is one of the best smoothie add-ins! It makes your smoothie creamier, tastier, and more filling.

Slicing and freezing bananas; measuring out almond butter.

Ingredients

  • Oats: Choose old-fashioned or quick oats depending on your texture preference; quick oats blend more smoothly.
  • Frozen Banana: Slice a banana into coins, store in freezer-safe containers or bags, and freeze overnight. Honestly, having a completely frozen banana (as opposed to an unfrozen one) is what makes this smoothie. (I like to prep the bananas right after my grocery store run so I don’t forget!)
  • Almond Milk: I love vanilla almond milk but feel free to use any milk you prefer, depending on dietary needs or flavor preferences.
  • Almond Butter or Peanut Butter: Use roasted and lightly salted butter for a deeper flavor. Stir well if you’re using natural almond/peanut butter that separates.
  • Maple Syrup: This is a natural sweetener that makes the smoothie taste amazing without refined sugars. You can adjust the sweetness by starting with a smaller amount and adding more after tasting if needed.
  • Ground Cinnamon: Did you know cinnamon has anti-inflammatory benefits? It’s amazing, and you can adjust this to suit your personal preferences.
  • Salt: Weird smoothie ingredient? Maybe, but it truly enhances all the other flavors and balances the sweet. We’re looking for the tiniest pinch — less than 1/16th of a teaspoon.

Adding oats to a blender; pulsing to a powder for this oatmeal smoothie.

How To Make Oatmeal Smoothie

  1. Freeze Banana: Peel and slice a banana, then freeze it overnight. A fully frozen banana makes the smoothie creamier and colder.
  2. Blend Oats: Place oats in the blender and pulse until powdered. Powdering the oats first ensures a smoother texture in the smoothie.
  3. Add Ingredients and Blend: To powdered oats, add frozen banana, almond milk, almond butter, maple syrup, vanilla, 1 teaspoon cinnamon, a pinch of sea salt, and 4-6 ice cubes. Blend until smooth. Add the liquid ingredients first for easier blending.
  4. Adjust and Serve: Taste the smoothie and add more maple syrup if needed, then blend again. 

QUICK TIP

Good ripe bananas make all the difference in this smoothie. Freeze the bananas when they’re ripe and use only when completely frozen for the best banana smoothie. The riper the banana, the sweeter the flavor!

Banana Oatmeal Smoothie Tips

  • Freeze the banana: While this Oatmeal Smoothie is quick and easy to make, it does require just a bit of planning the night before. Make sure to prep your bananas the night before so they’re frozen. If you forget don’t worry, just add a little more ice to get your desired texture.
  • Measure: It might seem silly to actually measure out ingredients for a smoothie instead of just throwing everything in, but I highly recommend doing so the first few times you make this so you get a feel for the quantities. Throwing random ingredients in a blender can often end up giving you way too much smoothie or tasting, well, nasty. 
  • High-powered blender: If you have a high-powered blender (I recommend a Vitamix® or Blendtec®), you can add everything in and blend until smooth. If your blender isn’t as powerful, follow manufacturer instructions for what ingredients to add first to make sure it blends well.
  • Adjust sweetness: Give your Oatmeal Smoothie a quick taste and if needed, add in a bit more maple syrup. Depending on the ripeness (and subsequently the sweetness) of the banana used, you may need more or less sweetener.

Variation Ideas

  • Add more protein: Add a scoop of your favorite vanilla protein powder or a tablespoon of hemp seeds for extra protein.
  • Add frozen fruit: We love adding a handful of berries or cherries, give this Cherry Crisp Smoothie a try to see the measurements.
  •  Spinach addition: Add a handful of spinach for added vitamin c and antioxidants. A little handful will change the color but you won’t taste it.
  • Spices: You can absolutely experiment with spices in this smoothie. In the fall, we love adding a pinch of Pumpkin Pie Spice or Apple Pie Spice. And if you’re a fan of cinnamon, feel free to add an extra sprinkle to this oatmeal smoothie.

  1. This smoothie sounds wonderful with the oats in it! I’ve been wanting to get a new blender so I can make smoothies because my super cheap Walmart blender barely works, haha.

  2. This looks fabulous, as always!! I love how similar our taste seems to be:-) Question, what plug-in do you use for your social media buttons at the top of your right column?

  3. 5 stars
    Oh my goodness. So much deliciousness in one recipe. Love oatmeal in my smoothies. So filling and satisfying. Thank you.

  4. This smoothie was pretty good. I loved the cinnamon! Instead of blending the oats dry, I soaked the oats overnight in a little water and they blended up very smoothly in the morning. Next time I’ll add less almond milk to make it a little thicker. Ideas for some variations would be to add some cocoa powder and substitute 1/2 cup of strong cold brewed coffee for 1/2 cup of the almond milk!

  5. 5 stars
    What a delicious, perfectly sweet (not too sweet) smoothie. The thickness is just right. Thanks for this recipe. My homemade smoothie concoctions just don’t have the right ratios.
