Peanut Butter Banana Smoothie Recipe Ingredients

Here’s what you’ll need to make this peanut butter banana smoothie recipe:

  • Peanut butter, of course! Creamy natural peanut butter is best for this recipe. Use store-bought, or make your own!
  • Frozen banana – It makes the smoothie sweet and creamy. To freeze a banana, remove the peel and place it in an airtight bag or container. It’ll keep in the freezer for up to 3 months. Tip: Wait to freeze bananas until they’re ripe and spotty. That way, they’ll have the sweetest banana flavor.
  • Whole rolled oats – They give the smoothie extra staying power and perfect its smooth, thick consistency.
  • Almond milk – Or any milk you like! Regular milk or my homemade oat milk would work here too.
  • And ice – To make the smoothie cool and frosty.

Find the complete recipe with measurements below.

Pouring almond milk into blender with smoothie ingredients

Place the banana, oats, and peanut butter in a blender, and pour in the almond milk. Blend until smooth. Then, add a handful of ice cubes and blend again.

That’s it! Pour the smoothie into 1 or 2 glasses and enjoy. If you like, top the peanut butter smoothies with banana slices, chocolate chips, and drizzles of peanut butter for a more decadent treat.

Peanut Butter Banana Smoothie Variations

We love this peanut butter and banana smoothie recipe as written, but it lends itself well to all sorts of variations. Feel free to change it up! I hope you have fun making it your own.

Here are a few ideas to get you started:

  • Swap the nut butter. Use almond butter or cashew butter instead of peanut butter.
  • Bump up the protein. Add a scoop of Greek yogurt or your favorite protein powder.
  • Spike it with a superfood. Blend in a tablespoon of chia seeds or a spoonful of maca powder.
  • Make it chocolatey. Add cocoa powder and a drizzle of maple syrup. A little vanilla extract would be great here too!
  • Or coffee-y. Mix in a splash of cold brew coffee.

Let me know what variations you try!

    I add a squeeze if Hershey’s syrup (or another brand) and we have called it a Chocolate Banana Whiz since I was a child (in the 50s- 60s, way before the term smoothie came into use.)

    That was amazing and my 2.5 yr old loved it too! We did just a small scoop of chocolate chips and tasted like a Reese’s blizzard with the consistency of a Starbuck’s frappuccino. Thank you!

    My PB-obsessed daughter started Kindergarten this year, and it’s a nut-free school. I made this smoothie for breakfast last week to get her PB fill in before the school day started. She and her 2 year old sister loved it. Thank you!
