Peanut Butter Banana Oatmeal Smoothie

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.

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.


  • 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.

  1. 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.

    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.

    1. 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!

  3. 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!

    If you wanna get crazy…use chocolate milk. Fairlife is really tasty and has extra protein and relatively low sugar for its taste.

    1. 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.

  5. Really yummy, exactly what I was craving. I used frozen banana, so less ice, and a bit more cinnamon and ate two servings:)

      1. 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!! :-) :-)

  6. 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!

  7. 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!
