Ripe bananas and natural peanut butter create a salty-sweet flavor combo in this protein-packed Peanut Butter Banana Oatmeal Smoothie. It’s perfect for breakfast or any time of the day.

In this Post: Everything you need for Peanut Butter Banana Oatmeal Smoothie
Aside from maybe chocolate, few foods taste better with freshly-roasted, salty peanut butter than a perfectly ripe banana. And aside from maybe pancakes, the best breakfast consists of smoothies. My Peanut Butter Banana Oatmeal Smoothie combines the best of both worlds and is morphed into a well-rounded breakfast thanks to yogurt, milk, and oats.
Ingredients
- Banana: Naturally sweetens the smoothie and adds a creamy texture.
- Milk: Use whatever milk you have on hand, any and all will work.
- Greek yogurt: Greek yogurt is higher in protein than typical yogurt, and adds to the creamy texture of the smooothie.
- Oats: I use old-fashioned oats, and they make the smoothie more filling while being a great source of fiber, calcium, and iron.
- Peanut butter: A huge source of protein, while also being creamy, delicious, and nutty.
- Cinnamon: Sweet and woody in flavor, cinnamon is a great way to get many antioxidants.
How to Make a Peanut Butter Banana Oatmeal Smoothie

Start your Peanut Butter Banana Oatmeal Smoothie by adding your banana to your blender.

Followed up by the milk.

Next add your Greek yogurt.

Then add your old fashioned oats.

And your peanut butter.

Finish with a sprinkle of cinnamon.

Put the lid on your blender and blend until smooth, adding ice until you reach your desired consistency.

Pour evenly into 4 cups, and serve and enjoy your Peanut Butter Banana Oatmeal Smoothie!
Easy Substitutions

Delicious smoothie, and I don’t even like smoothies. I’ll make this again and again.
I made one myself today and put nutmeg init
AMAZING, thank you :)
Of course! Enjoy!
The quantity of cinnamon in this smoothie is way too much – it overpowers the other flavours. Would be nicer without, or a fraction of the quantity.
Did you use the full amount of everything else including 2 bananas, milk, oats and yogurt? I think it’s perfect as is but you can always make it your own!
I noticed you don’t have the sugar content in the nutritional list. Also noticed it on another recipe. I’m diabetic and have to watch my sugar intake. Thanks.
Hi Dorothy – Just revised to include the sugar. I’ve been doing this for 10 years and some of my older recipes used a different program taht didn’t add the sugar in but we are working to add in on the 1500+ recipes. If there are any others you need just let me know! Sorry about that!
Delicious ????. The only change I did was add ( so delicious Dairy free alternative coconut yogurt )
I will definitely be making this smoothie again.
Thank you!
Oh great idea!
Can you make this with a non fat yogurt that isn’t Greek Yogurt? That’s all I have on hand
Yes absolutely!!
If you wanna get crazy…use chocolate milk. Fairlife is really tasty and has extra protein and relatively low sugar for its taste.
Dang good idea!
I just made a smoothie with a half a cup of oats a half of a banana a half a cup of 1% milk a tablespoon of peanut butter a half a teaspoon of cinnamon and a 3/4 cup of ice is that that fattening? What are the calorie intake.
You should try http://www.myfooddiary.com to calculate calories it’s great!
This might be a stupid question, but when the recipe says scoops of ice, is that ice cream or ice?
Ice ;)
Really yummy, exactly what I was craving. I used frozen banana, so less ice, and a bit more cinnamon and ate two servings:)
I’m so glad you enjoyed it Carrie!! Now I’m craving it too!
one of the worst smoothies ever
ugh…gross
Oh no I’m sorry you didn’t like it. It’s one of my favorites!
Loved this smoothie! Filled me up and kept me hiking all day (= I used half a cup of oats and added hqlf a cup of granola the second time around and it was amazing!! :-) :-)
So glad you liked it!!
Add almonds and less ice, oats, and peanut butter makes the smoothie 100 times better!!
but it was a decent smoothie!!!
Glad you found a way to make it your own!
This was amazing, Thank you!
I put in a little less oats and added 2 tablespoons of Barlean’s Flax, Chia and Coconut meal. Ummmm ummmm good
I’m so glad you enjoyed it Britany!!
Made this with my homestay sister today, we both loved it. Instead of normal milk, we used half normal and half coconut milk and it was super creamy and delicious! Took me 40 minutes to finish the whole glass and I feel super full- I won’t be needing any midnight snacks or anything. Thanks for this awesome recipe!
I’m so thrilled you enjoyed it!!!
This smoothie was SO good! I didn’t really follow the measurements and got a bit of a thick paste which I still ate of course but with a spoon. I used yogurt and no ice and found it more dense yet really good. Also blending with it nuts or crunchy peanut butter was a big YES. Thank you, its the perfect on the go breakfast, super filling!
I’m so thrilled you enjoyed it!
Really good! reduces the urge to snack!
So glad you enjoyed!
Really good! Thanks….reduces the urge to snack!
