Salty, nutty, and sweet. This peanut butter banana smoothie is such a pleasure, it could almost be dessert. Vegan, gluten-free, and soy-free.

A peanut butter banana smoothie is flawless in its simplicity. A perfect combination with nothing to stand in its way.

When you don’t want anything to distract from the joy that is PB & banana coming together, this is the smoothie you need.

The salty nuttiness of the peanut butter mellows the gentle sweetness of the banana. Flaxseed increases the whippy viscosity while adding omega 3’s.

Frozen bananas are a must

When it comes to smoothies, frozen bananas are essential.

You could just throw a banana into the blender right after peeling. But giving the banana time to freeze solid means that the smoothie will have a wonderfully creamy texture that it wouldn’t get otherwise. It pushes the smoothie almost into shake category.

To freeze bananas, peel them first. Break them into chunks. Then freeze in a freezer safe resealable bag or glass container.

When you’re ready to use the frozen banana, just pull out as many pieces as you need.

How to make this peanut butter & banana smoothie recipe

Here’s what you’ll need.

Blend the following in a high-speed blender until smooth:

Non-dairy milk
Frozen banana chunks
Peanut butter
Ground or whole flaxseed

If you’re not using a high-speed blender, you’ll need to grind the whole flaxseeds first in a clean coffee grinder, or use ground flaxseed. (Remember to store opened bags of ground flaxseed in the refrigerator.)

This peanut butter banana smoothie recipe makes enough for two small drinks. Even though they’re on the diminutive side, they’re quite filling with the PB & flaxseed inside. Or you can enjoy it in one tall glass.

Make it your own

Make this smoothie your own by varying the ingredients:

Use any non-dairy milk you prefer in plain or vanilla – cashew, soy, oat, or almond milk
Try it with a different nut butter like cashew, almond, walnut, or pistachio butter
Replace flaxseed with chia seeds or omit it altogether

I will second your thoughts on frozen bananas for smoothies. This is one of the many tricks you’ve taught me over the years for which I’m very grateful!

  I’m glad I was able to convert you to the frozen banana side. Whenever I hear that people are still using room temperature bananas for smoothies, I feel a little sad for what they’re missing! 😀

Bananas in smoothies are MUST for me. A smoothie just isn’t a smoothie without one. And a PB & Banana Smoothie is basically perfection in a glass. You’re making me crave one right now.

  I totally agree about bananas being essential to a smoothie. Plus, it seems like the other option is avocado for creaminess and body. Avocados are way too pricey & delicious to be hiding in a smoothie. Last week when I was creating/photographing this recipe, I had a PB & banana smoothie 3 days in a row. No complaints! 😀

The smoothie of course looks delicious—great idea to add the flax for texture and consistency! Plus healthy! My boys would love this, and we have a great nut free peanut butter sub that would be perfect!

  Thanks, Sarah! When it comes to smoothies, I always add chia or flax. I love that whippy viscosity that they give. That’s a great idea to do a peanut butter sub for your boys. You’ll have to let me know if you try it!
