Homemade Peanut Butter Oatmeal Smoothie

Smoothies that are healthy AND taste good are the best! And the ones that require a spoon instead of a straw are even better. This Peanut Butter Oatmeal Smoothie is loaded with creamy peanut butter, old fashioned oats, and soy milk. Even though it’s loaded with protein and healthy nutrients, it tastes like dessert in a glass!

This homemade smoothie recipe makes just enough for one serving. It is the perfect portion size for a snack, breakfast, or midday meal. But you can easily double it if you’re making smoothies for two. (That’s my kind of love language!)

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.

Key Ingredients

  • Oats: Rolled oats and old fashioned oats work best in this smoothie. I would not suggest using steel cut oats in this recipe, as they’ll result in a gritty smoothie.
  • Creamy Peanut Butter: You can use natural nut butter in place of the peanut butter if you prefer, to cut down on the sugar. Almond or cashew nut butter would both be delicious!
  • Banana: I like using frozen bananas in this smoothie. It keeps the smoothie extra thick, and it’s the perfect excuse to use up all those overripe bananas on your counter or in your freezer! If you do not like banana, then I would suggest substituting the banana with greek yogurt.
  • Soy Milk: Almond milk, cashew milk, oat milk, or regular milk can be substituted.

TIP: For an extra chilled smoothie freeze your banana first! You could also just add some ice cubes too!

How Much Protein Is In This Peanut Butter Oatmeal Smoothie?

This Peanut Butter Oatmeal Smoothie is loaded with protein. One serving packs in 14.7 grams of protein and 4.7 grams of fiber, making this a simple, yet filling, smoothie. Here’s where all that protein comes 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 (or until smooth), and stir. Blend again for another 30 seconds to 60 seconds after stirring to ensure there are no chunks. Pour into a glass (or a bowl), and garnish with banana slices, peanut butter drizzle and oats if desired. Serve immediately or place in the refrigerator until ready to eat. You can also double or triple the recipe to have extra on hand for the week!

How To Make a Peanut Butter Oatmeal Smoothie Recipe


  • Want more protein? Add some plain Greek yogurt, raw nuts (like almonds or walnuts), and flax or more chia seeds. You could even add a scoop of your favorite protein powder!
  • Incorporate some raw veggies! Spinach is easily hidden in this smoothie, but broccoli or carrots would be good, too!
  • Need it to be colder? Add some ice!
  • Add some more fruit! Apples, frozen berries, or kiwi would be great here.
  • Add a splash of pure vanilla extract for added flavor! Works well with the peanut butter and oatmeal.
  • Add spice: A touch of cinnamon or ground cloves would be amazing in this! This smoothie reminds me so much of oatmeal in a glass.

Storage and Freezing Instructions

This smoothie is best enjoyed fresh, but you can store leftovers in the fridge for a couple hours if needed. You can also freeze this prepared smoothie in an ice cube tray or freezer-safe container. Just re-blend it before enjoying later.

    Thanks for the 1 stop, 1 jar recipe- perfect!! I’m convinced- and a new follower! Anxious to see what’s ahead!!

  • Michael S

    Delicious and just the right amount for a single serving. Tastes like banana bread to me. I used a frozen ripe banana. Great recipe!

  • Pam

    Is it a problem to use almond milk instead of soy milk?

  • No that’s no problem! Almond milk would go great in this!



  • Megan

    Do you know anything that can be used instead of banana in it? I’m allergic

  • Hi Megan,

    You can always omit the banana the smoothie should still be pretty thick without it thanks to the oats. However you can always add some flax seed to bulk up the smoothie or canned pumpkin, frozen fruit, or even avocado.

    Hope these suggestions help! Thanks!


  • Pat L

    I don’t eat bananas either. Although, I wish I could simply because of the convenience. But they make me gag! I have a smoothie for breakfast 5 days per week. Through trial and error, I’ve discovered PEAR to be a good substitute for bananas. I plan on making this Smoothie on Monday morning. Really looking forward to it! Thanks!!!
