Peanut Butter Oatmeal Smoothie

Smoothies that are healthy AND taste good are the best! One’s that require a spoon instead of a straw are even better. This smoothie is loaded with creamy peanut butter, old fashioned oats, and soy milk. This smoothie tastes like dessert in a glass.

This recipe makes just enough for one serving. It is the perfect portion size for a snack, breakfast, or midday meal.

With only a few simple ingredients this smoothie comes together quickly. It can be made in under 5 minutes! Perfect for hectic mornings when you are running out the door.


  • Oats: Rolled oats and old fashioned oats work best in this smoothie. I would not suggest using steel cut oats in this recipe.
  • Creamy peanut butter: You can use natural nut butter in place of the peanut butter if you prefer.
  • Banana: I like using frozen bananas in this smoothie. It keeps the smoothie extra thick. If you do not like banana I would suggest substituting the banana with greek yogurt.
  • Soy milk: Almond milk, cashew milk or regular milk can be substituted.

Peanut Butter Smoothie Recipe

This Peanut Butter Oatmeal Smoothie is loaded with protein thanks to the creamy peanut butter and banana. One serving of this smoothie pack 14.7 grams of protein and 4.7 grams of fiber.

Here’s where all the protein is coming from

  • 1/2 cup of Soy Milk -> 4 grams of protein
  • 2 tablespoons Peanut Butter -> 8.0 grams
  • 1 whole Banana -> 1.2 grams
  • 1/4 cup Old Fashioned Oats  -> 2.7 grams

How to make a Peanut Butter Oatmeal Smoothie

To make the smoothie simply add all of the ingredients to a blender, blend for 30 seconds and stir. Blend for another 30 seconds to 60 seconds. Pour into a glass and garnish with banana slices and oats if desired. Serve immediately or place in the refrigerator until ready to eat. Double or triple the recipe to have extra on hand for the week.

If you have frozen bananas on hand you can always use them instead of fresh. It is a great way to use up leftover bananas!

  • I made a variation of this for breakfast today – I used almond milk and added half a scoop of chocolate plant based protein powder! So good and definitely one of the best PB smoothies I’ve had. Next time I’ll probably double everything, keep the PB amount the same because it didn’t make very much and I was totally craving more when I was finished drinking it. Great recipe, Kelley! 🙂

    Hi! This is a silly question but i’m genuinely not sure… Are you supposed to cook the oats first?

  • Hi Steph,

    Thanks for the question. No the oats do not get cooked before adding them in.



  • Mike

    Can you use single serve packets of “instant oatmeal” instead of old fashioned oats.

  • Hi Mike,

    I personally prefer the old fashioned oats in the smoothie. Regular oats can be substituted. I’ve actually never tried the instant oatmeal in this. It should thicken the smoothie up and give it texture so it should work. I just wouldn’t choose one with lots of flavor in it already (maybe plain or cinnamon and sugar). Hope this helps!

    Thank you,

    tip to cut down on the calories and add more thickness:
    use cashew milk…and add a touch of cinnamon.
    …and instead of peanut butter (225 cal per 2 tbsp)
    use either one tbsp and/or 2 tbsp of powdered peanut butter
    (only 45 cal and same lovely peanut taste with protein)
