Oatmeal Smoothie

As revved up and accomplished as I feel after drinking a filling breakfast smoothie, it’s not necessarily what I wake up craving, especially in January when I’m walking around my house wrapped in a blanket. This vegan Oatmeal Smoothie is an exception. Made with 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.

Filling and healthy Oatmeal Smoothie with peanut butter, banana, and cinnamon. With benefits like fiber, protein, healthy fats, and whole grains, this vegan breakfast smoothie will keep you full for hours! Great for breakfast, kids, and for weight loss too!

If you’re looking to make breakfast smoothies for weight loss a part of your 2019 goals, 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.

I’m also still mourning the end of the holidays, and a creamy oatmeal smoothie feels cheerier and a more gentle transition back to reality 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 from here until next December!

About This Oatmeal Smoothie Recipe

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 15 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.

Easy Oatmeal Smoothie with peanut butter and banana. A tasty and healthy breakfast!

Optional Oatmeal Smoothie Recipe Additions

The beauty of smoothies is their flexibility. Stock up on a few essentials, and you’ll have super 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. I do not need to cook the rolled oats or the quick oats?

  2. Can I use regular milk instead of almond milk? Thanks 

  3. I found your site while looking for NYE recipes. I made your Crock Pot Buffalo Chicken meatballs and they were a huge hit. In the past week, I’ve made 4 others of your 30-minute recipes with much success. I look forward to trying this recipe tomorrow morning!

  4. Hi Erin, We have banana and peanut allergies in our house. We can use Barney Butter they are only processed with coconut. What can we use instead of bananas as that is a hard one for us to swap out. Thanks

    • Hi Gina, you could try another fruit like strawberries, but the texture will be different and you may need to adjust for sweetness. See my notes in the blog post for making the smoothie without banana! I hope you enjoy it.

  5. Susan G Hutchins Reply

    Oh my! This is sooo good! I only used a little over half of a banana and didn’t use the maple syrup and it was so yummy!! I also use powdered peanut butter. Its like a dessert for me since I’m trying to cut out sweets after the holidays :) . I love your addition of the pinch of salt – I think it really popped the flavor!

  6. Christin Johnson Reply

    Will it still be the correct consistency without banana? I’m allergic to banana 😕

    • Hi Christin, unfortunately the banana contributes to the sweetness and smooth texture, so it will be different. In my blog post I suggest trying strawberries instead if you want a smoothie without banana, in case you’re interested in trying that flavor combo!

  7. Ok, I’ve been trying to do this whole smoothie thing every morning and today I tried this one…omg so good!!! Going to go check to see if you have any more smoothie recipes!

    • Hooray! I’m so glad you enjoyed it, Katey. I do have more smoothie recipes here, and I hope you love them if you decide to give them a try!

  8. Forgot to rate!

  9. Erin, I make a of smoothies and this is my favorite one! It tasted like dessert instead of a “healthy” smoothie. This will definitely help keep me on track with my health and fitness goals this year as I can use this smoothie as breakfast or anytime in between since it will keep me full. Thank you!

  10. This smoothie hit the spot. Thank you!!

  11. A smoothie that tastes similar to an oatmeal cookie…my husband would love that! Putting this on my list of your recipes to try. My list keeps growing daily! Thanks for this great idea. I have made many different types of smoothies but never one with oatmeal in it.

  12. Wonderful smoothie and I love the addition of cinnamon. I did use Irish steel oats and chunky peanut butter because that’s what I had on hand.  Delicious and thank you for the recipe and it’s definitely a keeper. 

  13. Delicious!

  14. Any ideas on how to make this more weight watcher friendl?. It comes up to 13 fsp but I really want to try this!  Thanks!

    • Hi Elaine, unfortunately I’m not familiar with Weight Watchers, so I don’t have any specific advice to offer. Perhaps someone else may chime in!

  15. Can I replace Kosher salt with Himalayan salt? 

    • Hi Janie, you can use your salt of choice, but to be safe I’d start with a little less than called for and salt to taste.

  16. Delicious!  Just like an oatmeal cookie. Thank-you very much!

  17. So glad I found your site. Tried this smoothie recipe this morning with the kids. One is super picky (but she loved it) and her pediatrician wants her to to give smoothies a try for weight management . She put on some weight over the past few months due to us spending so much time in the hospital and only getting quick not so healthy meals. Our hospital days are gone now that my son had his transplant and I’m working on getting them eating healthier.. a little over share, but I wanted to let you know you recipe is very much appreciated. Thank you. Saving your site and looking forward to trying others you’ve shared. 🤗

    • I can’t say enough how much this brightens my day. I am so glad this smoothie has been such a positive for you all <3 Wishing you even happier and healthier days ahead!

  18. Thanks for the recipe! Can I use steel cut oat?

    • Hi Brit, 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.

  19. Thanks for the recipe, just tried it and it was just what I was looking for. Looks like I have a new option for breakfast.

  20. Is it alright to use brown sugar & maple flavored oats? Thanks!

    • Hi Meagan, if you mean the instant oatmeal packet, I haven’t tried it with that. That’ll add considerably more sugar, so it’ll be a lot sweeter. You can certainly experiment, but I like the smoothie best with unflavored oats.

  21. Sooooo goood. Worried about the sugar. Probably will cut out the syrup.

  22. This rated amazing and probably would have been better if I used a frozen banana. This is an upgrade from the simple peanut butter banana smooth!

  23. Sara Hutchinson Reply

    Made it this morning! Very good. I dont think it needed the added salt, so I will skip that in the future. But it will definitely be regular part of my healthy meals routine!

  24. This was delicious and I’m not crazy about peanut butter, oatmeal or maple syrup. I was tired of berry smoothies. LOVED this!! :)

  25. what if you don’t gave cinnamon. can you still make it 

  26. Hi. I’m wondering how important it is that cinnamon be in the smoothie. I’m allergic and was wondering it it would still taste okay without the cinnamon.
