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.
Tip!
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.
- Cinnamon + Pure Vanilla Extract. Solidifies the oatmeal cookie flavor factor.

The Directions
- Add the oats to the blender.
- Pulse until fairly finely ground.
- Add the remaining smoothie ingredients, and blend until smooth. That’s it. ENJOY!
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.

Delicious! Makes me feel like I’m eating dessert! I don’t love banana so I just added more ice instead. Next time I’ll make it thicker as a smoothie bowl.
Hi Jasmin! So glad you enjoyed the recipe! Thank you for this kind review
WOW! Where has this been all my life! I used coconut milk instead of almond but it was truly delicious.
Hi Holly! So glad you enjoyed the recipe! Thank you for this kind review and feedback on the coconut milk!

Thanks Jasmin!
I’m doing a liquid diet for awhile and am needing different ideas to mix things up so I can stay consistent. I must say, I am so glad that I found your site! This smoothie is perfect and has me using ingredients in different ways and also ones that I don’t normally use. This smoothie turned out great! So tasty and satisfying. I look forward to trying the others :)
So happy to hear it was helpful for you Alisha!
Delicious & satisfying! I didn’t have any almond/dairy milk on hand so used plain nonfat Greek yogurt & added a few drops of water to thin it out a bit. I really loved the flavours. Used 1/2 Tbsp Maple Syrup as recipe suggested. Found it a little on the sweet side for my preference. Will try 1 tsp next time.
Hi Diane! So glad you enjoyed the recipe! Thank you for this kind review!

Hi Maria! So glad you enjoyed the recipe! Thank you for this kind review!
I modified this a little based on what I have access to, and it was AMAZING!!! My bananas weren’t frozen, so I used 4 ice cubes, 1 banana, and a vanilla meal replacement powder. SOOOOOO GOOOD!!!!!! Will try with almond butter and vanilla almond milk next time! :)
Hi J.S.! So glad you enjoyed the recipe! Thank you for this kind review!
Very easy to make and to swap ingredients.
Hi Zaida! So glad you enjoyed the recipe! Thank you for this kind review!
SO delicious yet simple and healthy
Hi Sabrina! So glad you enjoyed the recipe! Thank you for this kind review!
Hi Erin
I have made some of the healthy smoothies and its delicious.
I would like to know whether i can add Kale powder instead of raw Kale or Chlorella powder in the smoothies. It would be great if you could share some recipe.
Thank you.
Hi Leena! You probably could, I just haven’t tested it out myself in this recipe. I have added protein powder to smoothies before and they have worked out great! If you decide to experiment, I’d love to know how it goes!
I have made this this smoothie for a few weeks in a row! First, good idea to follow your recipe and grind the oats alone in blender as it thickens the smoothie better (I did it the other way a few times…). I make the peanut butter version, but occas. sub tahini. I love to top with nutmeg, too. I will give your kale pineapple smoothie a go, too!
Hi Amy! So glad you enjoyed the recipe! Thank you for this kind review!
Could you use peanut butter powder with this?
Sure! Enjoy!
This is the first recipe I think I have ever reviewed. This is fantastic! I made it just as directed except I used almond butter instead of peanut butter and omitted the sweetener (no honey or maple syrup).
Thank you for this great recipe!
Yay! Thank you Jessie!
