Fluffernutter Banana Smoothie


This post may contain affiliate links.

It’s a bit of a funny name, but fluffernutter is just code for two favorites rolled into one:

Fluffer = Marshmallows

Nutter = Peanut Butter

Add bananas, and you’ve got yourself a fabulous treat.

Marshmallow Peanut butter and banana smoothies

This borders on dessert-in-a-cup and that’s just fine by me on this hot holiday weekend.

I almost added cocoa powder but would have had to crack the seal on a new container and figured it wasn’t necessary and as it turned out, not adding cocoa powder allowed me to concentrate more fully on marshmallows without chocolate clouding my judgment. We’ve all been there.

I love the top layer of hot chocolate with an abundance of softened marshmallows. It’s one rare situation in which I enjoy mushy and squishy food. And this smoothie is another.

Some marshmallows are blended into the body of the smoothie and a few more are added as a garnish. Slurping those softened little squishy white globes is so much fun.

I added enough peanut butter that this frothy little number turned amber-hued. I wasn’t complaining.

It was cold and creamy and went down fast and easy.

Bananas go from good to great when they’re frozen and then blended. They add so much creaminess and fluffiness to smoothies and this was no exception. Plus, peanut butter and bananas is always a good combo.

Nah, I never missed the cocoa powder in this one.

Fluffernutter Banana Smoothie (vegan and gluten free, as indicated below*)

Makes about 12 ounces

2 ripe small/medium bananas (previously frozen in chunks is preferred)

1/2 to 2/3 cup cream or milk (or vegan milk)

1/3 cup creamy peanut butter

2 tablespoons granulated sugar, optional and to taste

1/2 teaspoon vanilla extract

1/3 to 1/2 cup mini-marshmallows

Combine all ingredients except for marshamllows in a blender and blend until smooth and creamy. Add marshmallows and pulse or blend until just incorporated, allowing some texture to be retained. Garnish with a few additional marshmallows. Serve immediately.

Optional add-ins: 1 to 2 tablespoons cocoa powder, 1 whole graham cracker, 1/ 4 cup semi-sweet, peanut butter, or white chocolate chips or chocolate syrup; 1/4 cup shredded coconut flakes, 1 to 2 ounces marshmallow-flavored vodka or light rum, 1 scoop protein powder, add 1 scoop of ice cream for a milkshake, garnish with whipped topping or whipped cream, coconut flakes, graham cracker crumbs, dollop of peanut butter, or sprinkles.

*To keep vegan, use vegan marshmallows (here or here) and vegan milk (coconut, cashew, almond, soy, rice). Most conventional-brand marshmallows are inherently gluten-free but use those that are linked for certified gluten-free marshmallows.

Do you like marshmallows? Peanut butter?

The fact that many of my favorite recipes use marshmallows and peanut butter, and bananas, at least shows I’m consistent. Peanut butter recipes and comparing peanut butter never gets old. Nor do marshmallows. Or bananas.

    1. I linked TWO brands of vegan marshmallows and as I told another commenter, not much I can do past that other than give folks the info about how to make this vegan and then let people make their own choices :)

  1. Yum any smoothie with peanut butter and banana in it is my favorite so adding marshmallows tops it off! :) I just made peanut butter at home last night thanks to your inspiration!

  2. This sounds sooo tasty and indulgent! Marshmallows and PB are definitely a match made in heaven! And since I have an abundance of bananas this week so I just may give it a shot ;)

  3. I’m not sure I’ve ever had fluffernutter, though I’ve certain enjoyed the two main components. This makes me want to try it! Gorgeous as always.

    1. Exactly. Which is why I provided links to TWO types of vegan marshmallows. Not much more I can do other than provide the info and after that, folks need to do their own homework and make their own choices.

  4. What a blast from the past! I don’t know if it’s carried in the grocery stores outside of the Boston/New England area, but Fluff was a staple for me in the ’70s.
    Yum, ice cream sundaes with fluff, and fluffernutter sandwiches in my Wonder Woman lunch box. it’s all coming back to me now…. Oh, but as I grew older and more sophisticated, I began to use Nutella instead of PB. LOL

  5. sounds amazing! growing up, I had a friend who always had a fluffernutter sandwich on fridays at school. i was always so jealous! haha

  6. I like the name: fluffernutter…:) As of your question… I think I am going to comment on another posts, I’ve missed a few… :)

  7. This is inspired, Averie— I love the idea of blending the marshmallows. And now I’m also craving your white chocolate marshmallow cake bars!

    1. I don’t know how inspired it is, but it sure is good. A little too good :)

      And okay those white chocolate marshmallow cake bars – the photography is a little iffy but seriously, one of the best desserts on my site. Totally ripe for improvisation, too. Make them for your girls!

  8. Great combination of flavors and textures. I never thought to put marshmallows with pb and banana! Plus, I love the photos looking directly down in the glasses. Could we just dive right in, please? ;-)

    Truth be told, my heart always skips a little beat when I look at the photos of those white chocolate vanilla marshmallow cake bars. White chocolate is probably one of my favorite things in the world to eat. Drool!!

    1. I knew you liked the white chocolate vanilla marshmallow cake bars but I didn’t realize how much until a few comments ago (I was in Aruba) and remember reading your comment about how much you REALLY loved them – good to know :)

  9. Pretty sure you’re either a mind reader or secretly hiding out in my apartment, ha! I’m having the toughest time keeping up with bananas lately (i.e., they ripen way faster than I can eat them) and fluffernutter is my absolute favorite childhood combo. I think I have no choice but to make this. ;)

  10. Growing up, my sister would always ask for fluffernutters and I would ALWAYS ask for PBJs. She loved them SO much and whenever I see PB & marshmallow together, I think of her. I’ve grown to LOVE pb & marshmallow together, esp marshmallow creme. I’m actually convinved PB goes with just about anything. :)

    The melty soggy marshmallows at the top of the hot cocoa are my favorite too. Being a texture freeeeeeak, I gotta have at least some “chunks” in my smoothies too. Whether that means a few chunks remaining from the frozen banana or a a handful of bluberries throw on top, or in this case… some marshmallow… I love the extra texture. PB, fluff, and banana sounds too good to be true.. a combination I’ve NEVER tried!!!!

    1. that’s a cute story about your sister – truth be told, I’d probably side with the PB & J rather than fluffernutter – we think alike! And yes, PB goes with anything!

      Texture freak is my middle name. There has to be many diff textures going on and never just one-dimensional. That’s why I love making bars so much is there are so many ways to add diff textures!

  11. This looks insanely delicious! And genius too! Gorgeous pictures as always, Averie! Have a great weekend!

  12. Be still my heart! I love me some fluffernutters and this smoothie looks INCREDIBLE. So light and frothy and the marshmallow “sprinkle” on top is not only adorable, but super tasty. Love that they soak up all that banana and cocoa-y goodness.

  13. I love the fun, whimsical name of this smoothie and it sounds yummy too! PB, bananas, and marshmallow is a great combination (I have been known to put all of that on a bagel and then brown the marshmallows under the broiler). I made a small loaf of banana bread and it is so good–truly a great recipe Averie! I wish I could have used my homemade vanilla but it won’t be ready for a couple of weeks.

    1. The next 3 weeks of banana bread are already typed and pics taken. You are going to love them I think! They all start with this recipe as the base, and then branch out, and the icing/glaze is even one-up’ed if I do say so myself. I hope you made that part and glad you loved the recipe!

      I have homemade vanilla going too but couldn’t start it til after Aruba so I have like 5+ weeks to go. ugh.

      And ‘all of that on a bagel and then brown the marshmallows under the broiler’ <--Wow.Yes.please.

  14. Fluffernutters are the best, especially because of the funny name! They were always a serious treat as a kid, since marshmallow fluff was a rarity around here. Marshmallows are still my great weakness, so I’m craving this more refreshing version of the classic like crazy! Those pictures are so enticing.

  15. Yum! Marshmallow, peanut butter, and bananas are three of my favorite things . . . not to mention staples in my diet.

  16. Fantastic!!!! I need to make some homemade nut butter today. I love peanut butter…marshmallows are good in certain recipes and I think this is one of them.
