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

Cad, I can imagine as clear as day you and David carrying out your banana phone shtick. No one would be better at it! And 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!
Cadry says
We’ll have to get the girls involved next time! It can be the new, “Do you like pancakes?” 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! 😀

I love that you talk to King Kong on a banana phone! Matt and I have inside jokes too and sometimes we say to ourselves – “what if someone was actually listening to us, they’d think we’re crazy!”.
I, on the other hand, do not think you’re crazy and I think it’s awesome. 🙂
Your smoothie sounds perfect. I love a good banana and peanut butter anything. 🙂
Cadry says
Haha! Thanks for clarifying that you DON’T think we’re crazy! 😀 It seems to be a natural part of couple-dom that you develop your own language with time.

Thanks for another few innovative recipes.
Love peanut butter and banana, so if this smoothie is as delicous as it looks, then am going to be real happy!. Can’t wait to try the PB cookies, yum, yum!.
Cadry says
Thanks, Simon! I hope you love this smoothie as much as I do. Since you are a fan of peanut butter & bananas, I bet you’ll be into it! And yes, those peanut butter cookies are delicious. I need to make another batch!
Dianne says
Your banana telephone running joke is so cute! I’m not a big fan of bananas, but I don’t mind them in smoothies, and this one looks like something I’d really like!
Cadry says
Thanks, Dianne! That’s too bad that you’re not a big fan of bananas, but maybe the peanut butter would win you over.
Bianca Phillips says
Hahahaha, y’all are so cute!
“And after the movie plans have been finalized, the phone can be eaten on its own or frozen for a smoothie.”
Hahahahahaaha. I’ll never look at a banana the same again.
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.
Cadry says
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! 😀
Amey Mathews says
ha ha. Hello? Are you there? I can’t hear you! This is bananas!
“Bananas!” is my favorite expression lately. These smoothies look so good. I almost never buy bananas, since we have an abundance of local organic fruit to choose from, throughout the year… but a couple times a year I”ll splurge and buy some. I actually have a few that went brown in the freezer — waiting to be made into banana muffins sometime soon!

Cadry says
Cute, Amey! I like your punning! 😀
Yes, with the abundance of local produce in California, I can see why you stick to what’s readily available. You’ll have to give this recipe a whirl during one of your splurges. 😀
Amy Katz from Veggies Save The Day says
I love this story! So cute. And this smoothie looks amazing! I love peanut butter and bananas.
Cadry says
Thank you, Amy! Peanut butter and bananas are just so good together. It’s a perfect match!
Jenn says
Bahahaha! Love your little joke! And I love peanut butter banana smoothies! Totally like milkshakes – yum!
Cadry says
Thanks, Jenn! We definitely embrace silliness around here. I’m glad you’re a fellow PB & banana smoothie fan. 😀
Sarah says
You two are hysterical! I can totally picture the two of you in your kitchen doing this routine! And 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!
Cadry says
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!
Susan says
You two are hilarious! I love it.
Cadry says
Thanks, Susan! <3
David says
So delicious and healthy too!
