As revved up and accomplished as I feel after drinking a filling breakfast smoothie, it’s not necessarily what I wake up craving, especially during the cooler months when I’m walking around my house wrapped in a blanket. This vegan Oatmeal Smoothie is an exception. Made with easy ingredients like bananas, peanut butter, and cinnamon, its cozy flavor and creamy texture trigger sensations of comfort, all while fueling my body for a healthy day ahead.

If you’re looking to make breakfast smoothies for weight loss, add extra servings of fruits and veggies to your diet, need a balanced smoothie for post-workout recovery, or just want a yummy, filling way to nourish your body, this banana oatmeal smoothie recipe is one you’ll want to sip over and over again.

If you’re new to the smoothie game, it’s also a delicious, approachable place to start. Personally, I love green smoothies (especially this Kale Pineapple Smoothie and this Apple Avocado Smoothie), but I recognize that those who are newer to the smoothie game might want to tiptoe their way in a bit (this Apple Smoothie is another great place to start).

A creamy oatmeal smoothie also feels like a cheerier and a more gentle smoothie than something super dark and seriously green.

With its sweet banana base, warm oats and cinnamon, and the decadent taste of peanut butter, this smoothie tastes like an oatmeal cookie.

I might not be able to eat actual cookies for breakfast forever, BUT I can have a hearty breakfast smoothie that tastes like one any morning!

About This Oatmeal Smoothie Recipe

The Ingredients

The ingredients you will need to make this quick and healthy breakfast smoothie are:

  • Oatmeal. A seriously underrated smoothie ingredient! Oatmeal is rich in fiber, and it makes smoothies satisfyingly thick and ultra filling. This oatmeal smoothie will keep you full all morning, and the oatmeal is a big part of that.

Because the oatmeal is ground in the blender, you can use any kind of oats you have on hand. I most often use rolled oats, but quick oats work too. If you are making an instant oatmeal smoothie (using instant oatmeal packets), make sure the packet isn’t sweetened or flavored.

Three other favorite breakfast smoothies with oats: Blueberry Banana Smoothie (this one tastes like blueberry pie!), Strawberry Kiwi Smoothie, and Blueberry Cream Oatmeal Smoothie. You can also add a few tablespoons of oatmeal to any one of these Healthy Breakfast Smoothies.

  • Frozen Banana. The next time you have spotty bananas on your counter, peel and cut them into pieces, then freeze them in a ziptop bag. They make any smoothie thick, naturally sweet, and creamy.

If you are in a hurry to freeze your bananas, you can cut the slices thinly and spread them in a single layer on a parchment-lined plate or baking sheet. Pop them in to your freezer, and they’ll harden within a half hour.

If you don’t have any frozen bananas, you can use fresh banana. Your smoothie will be more liquidy, so pop in a few ice cubes at the end to thicken it up.

  • Peanut Butter. The healthy fat and protein in peanut butter are a big part of what makes this oatmeal smoothie so filling. It’s just the touch of richness the smoothie recipe needs to taste satisfying and not like something you’re stuck eating.

Any kind of creamy peanut butter will work here (shelf stable or drippy), so feel free to use your favorite. You can use crunchy peanut butter also, though I prefer the smoothness of creamy.

  • Maple Syrup. I’m a sucker for the flavor of maple and oatmeal together. A half tablespoon was plenty for me, but feel free to adjust to your taste.

Maple syrup makes this oatmeal smoothie vegan, but you can swap honey if that isn’t a concern.

  • Almond Milk. Unsweetened plain or unsweetened vanilla almond milk is my fave for smoothies. If you can’t tell, I’m a wee bit compulsive about my smoothies being creamy, and since almond milk is creamy on its own, it adds to the effect.

That said, feel free to use any milk you like. The oatmeal smoothie is quite thick as the recipe is written, so if you prefer a thinner texture or your blender is struggling, splash in a little extra.

  • Cinnamon + Pure Vanilla Extract. Solidifies the oatmeal cookie flavor factor.

Optional Oatmeal Smoothie Recipe Additions

The beauty of smoothies is their flexibility. Stock up on a few essentials or survey what you already have, then use them to blend up healthy breakfast smoothies on demand!

  • Strawberry Oatmeal Smoothie. Replace half of the banana with frozen strawberries. If you’d like it to be a peanut butter oatmeal smoothie no bananas, you can replace the bananas with strawberries entirely.
  • Extra Protein Oatmeal Smoothie. Add a scoop of your favorite vanilla or chocolate protein powder.
  • Green Oatmeal Smoothie. Ready to embrace the green? Add a handful or two of spinach. It will change the color, but the taste is imperceptible. If you are looking to slide a green oatmeal smoothie past picky eaters and hiding the green is important, consider adding oatmeal to a darker, berry-colored smoothie like this Blueberry Avocado Banana Smoothie, or add a few handfuls of blueberries or raspberries to this recipe.

  1. Only one word to explain it -AMAZING. My wife and I including my kids loved it… but I added extra peanut butter we love peanut butter…. So Yummm!!!5 stars

  2. I’ve never posted a comment for a recipe before today. I felt that I had to for this smoothie…it’s that delicious ? I liked that you included how the ingredients make it all come together. Thank-you5 stars

  3. Made this for my daughter and I for a light lunch on a busy day. Dog spa day and trying to get a head start on spring cleaning.

    We both loved it!

    I did use coconut milk and replaced the maple syrup with a drizzle of black strap molasses.

    It will definitely be a regular in our rotation.

    Stay safe ?5 stars

  4. This is a great smoothie to kick off the day. Breakfast all in one…family favorite. Thank you for the recipe!5 stars

    1. Hi Em! I haven’t tried that myself, but it may work if you have a high-powered blender. My concern would be that it wouldn’t get ground up as much as rolled oats. If you decide to experiment, I’d love to hear how it goes!

  5. such a good mid-day pick me up between lunch and dinner. SO creamy and delicious. perfect amount of sweetness. I didn’t have frozen bananas, only at room temp. But just added some ice cubes to chill it… I think these would taste amazing frozen into popsicles (hmm).. will try next time! Thank you for sharing.5 stars

  6. Wish I had the recipe yesterday to freeze the banana, but I had frozen strawberries. I was looking for a smoothie recipe that had oatmeal. This fit the bill. Thanks!5 stars

  7. The ONLY oatmeal smoothie recipe you need in your life!!! I have a tendency to put some kind of nut/seed butter and fruit in my oatmeal but always thought it was weird when people said they put oats in their smoothies – probably because I really only like steel cut oats, not rolled or quick oats. I had tried a few oatmeal smoothies in the past and wasn’t a fan of any of them. It’s been a while so I tried again when I found your recipe…And it changed my mind! I made quite a few subs for what I had on hand but kept the measurements. Just shows how versatile the recipe is and that it will be great to use up whatever fruit or milk I have on hand when I make it!

    My subs were: about 3/4 cup raspberries for the banana, unsweetened macadamia milk for the almond milk, agave for the maple syrup and I skipped the cinnamon only because of the fruit I used. Added a teaspoon of chia because why not – and I *may* have also doubled the peanut butter because I love it. Keeper recipe for a drinkable version of the oatmeal I love! Thank you!!!5 stars

  8. This was amazing! I threw a handful of spinach in and put the smoothie in a large coffee mug. No one even knew they were eating veggies! It was delicious and filling. Thanks for the recipe!5 stars

  9. Hello Erin! Could you please tell me for how long can this peanut butter oatmeal smoothie be stored in refrigerator ? Or is it just a one go recipe?

    1. Hi Anushka! This smoothie is best enjoyed the day it is made, but you can refrigerate leftovers for up to 1 day. I hope you enjoy it!

  10. This is delicious! Will be making this often. I had a nasty fall a few days ago and can’t eat any solids at the moment, (my face took the brunt) so I was very happy to find your website. ?5 stars

  11. I absolutely loved this recipe ! I like oatmeal but get tired of eating it the plain old way :)
    This is such a great way to have it . Also , it kept me full for hours and kept my blood sugars in check ! I highly recommend it !
    Looking forward to checking out more great recipes ! Thank you !5 stars

  12. Perfect recipe! Filling and nutritiou…I like to use almond or pumpkin seed butter, and use golden milk spice blend, just to get it all in! Smoothys are helping me lose some weight and lower my cholesterol…5 stars
