Mornings can move fast—especially when you’re getting kids out the door and juggling all the things. This oatmeal smoothie was made for those days when you need something heartier than fruit alone, yet still quick enough to blend and go.

Rolled oats give it staying power, frozen banana makes it creamy, and a touch of vanilla brings that cozy, just-sweet-enough flavor that feels like comfort food in a glass. It’s the kind of breakfast that keeps you fueled, steady, and satisfied until lunch.

Labeled Ingredients for a banana oatmeal smoothie.

Ingredients You’ll Need

Here’s what I put in my oatmeal smoothie in the morning.

  • Rolled oats: Contribute a subtle nuttiness and a smooth, creamy texture that blends beautifully into the smoothie. For the best flavor, opt for fresh, high-quality oats.
  • Coconut milk: Brings a lush, velvety texture and a hint of tropical flair. Choose unsweetened coconut milk for better control over the sweetness. Here is my guide for the best coconut milk brands or you can learn how to make coconut milk.
  • Frozen banana: Delivers natural sweetness and a luxuriously thick texture. For maximum flavor, use bananas that are fully ripened before freezing. You can see my guide on how to freeze bananas if you need more tips. 
  • Ground cinnamon: Adds warmth and complexity with its sweet and spicy undertones. A pinch can make the flavors pop without overpowering the smoothie.
  • Vanilla extract: Infuses the smoothie with a touch of sweet, fragrant depth. Look for pure vanilla extract for a more robust flavor.
  • Homemade protein powder (optional): I love this blend of hemp, flax, and chia seeds. It adds a natural boost of protein to any smoothie and is great for breakfast.

How to Make Banana Oatmeal Smoothie

My banana oatmeal smoothie is easy and the perfect breakfast to start the day off right. You can make it any morning with these quick and easy steps.

  1. Put the rolled oats, coconut milk, frozen banana, cinnamon, and vanilla extract into a blender.
  2. Start blending at a low speed to combine the ingredients, then gradually increase to high speed. Blend for about 1-2 minutes, or until the mixture becomes smooth and creamy.
  3. Pour the smoothie into a glass and, for an extra touch, sprinkle a pinch of cinnamon on top or garnish with a few rolled oats.

Easy Swaps and Add-Ins

  • Too thick: If your smoothie is too thick, add a little coconut milk and blend again until smooth. 
  • Too thin: Add another half a frozen banana for a thicker smoothie.
  • Swap coconut milk: If you’re watching your calorie intake, opt for lighter versions of coconut milk. 
  • Add frozen fruit: For a refreshingly cool smoothie, be sure to add at least one kind of frozen fruit.

Common Questions

Can You Put Oatmeal in a Smoothie?

Yes, you can put oatmeal in a smoothie! You get all the benefits of a bowl of oatmeal, yet in a smoothie form. Oatmeal is loaded with fiber, which boosts the good bacteria in your gut. Whether you need an on-the-go breakfast or you crave a refreshing sippable morning meal, this delicious banana oatmeal protein smoothie is a great option.

Can I make a banana oatmeal smoothie without a blender?

While a blender is ideal, you can try mashing the banana and mixing it with finely ground oats, milk, and other ingredients, though the texture may not be as smooth.

What substitutions can I make for a banana oatmeal smoothie?

You can replace bananas with other fruits like mangoes or berries, swap almond milk for dairy milk or other plant-based options, and add protein powder or nut butter for extra nutrition.

How long can I store a banana oatmeal smoothie?

You can store a banana oatmeal smoothie in an airtight container in the refrigerator for up to 24 hours, but it’s best enjoyed fresh for the best taste and texture.

    I did not have coconut milk and used almond milk.
    It was absolutely delicious ! Love this recipe because you do not need a lot of different ingredients and it is simple and easy to make.

    1. Almond milk is a rawkin swap! Thanks for giving it a blend!

  2. 5 stars
    This was very good! Thank you for sharing your recipes! I didn’t have any coconut milk, I used oat milk instead, turned out very creamy and delicious!

    I used full fat coconut for a creamier smoothie, but the coconut flavor and texture overpowered the oats and bananas :/ I would recommend using a lighter coconut milk. I’m planning on trying it again and hope for a better outcome!

    Reply

    1. Thanks for the feedback Anna! Def let us know what you think with your next blend!

    1. Hi Monica! Quick oats would work just fine here.

  5. Has anybody tried this with regular cow’s milk instead of coconut milk? If so, how’d it end up?

    Reply

    1. We think it’d be just as good with cow’s milk, yet haven’t tried that option out. Anyone else? If you give it a blend with the moo let us know! 🙂

    2. Update: I tried it with 1% cow’s milk, and it turned out delicious! Reminded me of an oatmeal cookie.

    3. Thanks so much for the update Mike!! Good to know. Heading for my blender now…

    4. I tried it with cow’s skim milk and omitted the syrup. It was sweet and delicious.

    1. Irish or steel cut oats would work just fine in this smoothie. 🙂

  7. Anybody try this with a little spinach? Seems like the taste wouldn’t change too much.

    Reply

    1. I think that is a great idea. If you don’t use too much, the green makes them suspicious, they or you will never taste it,

    2. Spinach is really mild and a bit of it would work great here! Give it a blend and let us know what you think.

    1. Our fav is homemade coconut milk, which is super easy to make. Check out How to Make Coconut Milk. Yet, if that’s not an option we use full-fat canned coconut milk too. 🙂

    I’ve made this smoothie almost every day for the past two weeks. I like it to be more like thick milk (versus a smoothie) so I can quickly slurp it down, so I use a non-frozen ripe banana and add ice when blending to make it cold. My toddler godson tried it for his afternoon snack and loved it too. Thanks for a wonderful, simple recipe.

    1. Oh no, sorry about that Kim! These deals are dependent on timing and inventory and Vitamix may be all out of the blender that was listed in Jen’s secret deal. Def sign up for our newsletters if you haven’t already; we often team up with Vitamix to offer special deals on their awesome blenders! 🙂

  11. My new favorite smoothie. I used Almond Milk, which I normally have in the house rather than Coconut. Thinking of adding some cocoa for a chocolate version.

    Reply

    1. Adding cacao powder for a chocolate version would taste delish!

  12. Can’t wait to try this! Is it okay to have this banana oatmeal smoothie EVERYDAY? Keep rawking on!

    1. Hey Sam! Sure, you can drink the same smoothie every day if you like! But def check out our other awesome smoothie recipes if you decide to mix it up and try some different ones!

    This smoothie is amazing! It was like dessert. I seriously almost licked the blender clean. I followed the recipe, but didn’t get more than 8 ounces out of it, the recipe says 16. Not sure what I did wrong.

    Reply

    1. So glad you loved it— it’s really, really good! And you didn’t do anything wrong Julia. We had an issue with the serving size with the recipe card. I just went in and fixed that and now it should get you that full 2 cups of goodness. Keep on rawkin’ girl!

    1. After you try it, come back and let us know what you thought, Iris!

    I just made this smoothie for dinner— yep. Was out doiing yard work and the time flew by and I didn’t want to cook something, so I decided to embrace Smoothie Sunday. And this smoothie was AMAZING! I loved how substantial it was (def makes a good meal!). The flavors we’re nice too— great job Jen and the rawkstar team!

    1. That sounds like a great and simple dinner! I’ve eaten oatmeal for dinner so why not an oatmeal smoothie?! 🙂

    2. 5 stars
      This was delicious! I used homemade coconut milk with a scoop of cashew cream.

  16. 5 stars
    Another hit….added a touch of maple syrup and a teaspoon of almond butter….perfection….thank you.

    Reply

    1. Using canned coconut milk will give your smoothie a creamier texture but either one will work!

    1. I think adding a little bit (maybe 1-2 Tbsp.) of nut butter would taste great in this smoothie! We prefer almond butter over peanut butter but I think any type of nut butter would do. 🙂

  19. It’s always nice to receive a new smoothie recipe, regardless of the day or time (it’s now 5pm here in Greece). This one looks simple and delicious. I have been adding 2 tablespoons of oats to my smoothie every day for the past 5 months in order to help lower my LDL cholesterol level (and with success).
