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.

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.
- Put the rolled oats, coconut milk, frozen banana, cinnamon, and vanilla extract into a blender.
- 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.
- 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.

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.
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.
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.
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 just made this and it was yummy. I did 1.5 of the ingredients and got 2 servings. I had to use up a can of Coconut Cream so that is what I used. I think my bananas could have been more ripe, but they were frozen. I did add 1 tablespoon of pure cane sugar. To me it was my dessert.
I’m so happy you enjoyed it! It’s a fave, for sure. And it’s so nice to have a healthy treat to make when you’re craving sugar.
This smoothie was delicious
Thanks for trying it, Asia!
Delicious! I also added some peanut butter.
Yes- that would be tasty! Good idea Xio!
Could you add Greek yogurt to this as well?
You can add or subtract whatever you want to your smoothie, Beverly! After all, we want these smoothies to work for you. We might recommend a plant-based & unsweetened yogurt, but if Greek yogurt is your preference, that sounds good to us. 🙂
This is so yummy! It looked so simple and I had everything to make it. I didn’t expect it to be so full of flavor!! I will be making this often! Thank you!!!
I made this recipe this morning and I could not believe how full I was all morning. I have never added oatmeal to a smoothie before!! This was delicious and so easy to make as I had all the ingredients on hand. Thank you, Jen for all these wonderful recipes.
So glad you enjoyed it!
I made this smoothie with 2 cups of oat milk, in place of the rolled oats and coconut milk, then followed the rest of the recipe for two. We loved it!! I can’t say a bad thing about it.
It was our lunch smoothie as we did the 10 smoothies for lunch each day, No bread, cheese or deli meat!
We are so looking forward to the soups! Some are so new to us, it will be an adventure.
Thank you Jen and staff for providing a great website with all of the amazing drinks!!!

Way to rawk a healthy breakfast, Danyell!
Loved this smoothie, but what about soaking the oats beforehand? The same questions goes for you oat milk recipe, which I am dying to try.
Thanks,
Dr. D.
If you’re up for it, soaking the oats for several hours before blending in this smoothie (or making oat milk) is a great idea! It reduces the phytic acid and the starchiness of the oats, allowing for better absorption of the nutrients in them.
I added raspberries in this when I made it, and it was SO good! A filling breakfast recipe.
Loved this and it’s so versatile! I tried adding a little kale and some frozen blueberries. The berries seemed to hide the kale color and flavor and it tasted kind of like a cross between blueberry muffins and banana bread
Oh! And pulsing the oats a few times in the blender before adding everything else made it turn out more smooth for me:)
Love the upgrades Annie! Rawk on!
I am wondering about the use of coconut milk or coconut oil.. I have heard many people say there is too much fat in it. What say you Jen?
