Protein Fluff

My favorite way to drink my protein shakes is in the form of what I call “fluff“.

Two things make my protein shakes look and taste like a milkshake. A frozen banana and a food processor. I’ve figured out the combination of these two things make a wonderfully whipped shake that resembles the Wendy’s frosty.

Caught your attention?

I do multiple variations of these shakes but below are the key ingredients:

  • 1 frozen banana (in slices)
  • 1/4 cup of unsweetened vanilla almond milk
  • 1 scoop of protein powder of choice- my favorite!
  • a handful of ice cubes
  • a food processor (I use one similar to this Cuisinart)

If you want to add more fruit to your shake, sometimes I do frozen strawberries or blueberries when using my plain vanilla powder, nix the ice cubes!

Here is exactly how I make my shakes:

  1. Pulse the frozen banana in the food processor for about 5-10 seconds
  2. Add the almond milk and mix for 5 seconds
  3. Add the protein powder and mix for 1 minute continuously
  4. Add the ice cubes and mix continuously for 2 minutes (or the frozen fruit)
  5. Pour and enjoy!

Vanilla bean fluff! Vanilla protein powder, 1 frozen banana, 2 madagascar vanilla beans, ice cubes, and unsweetened almond milk

I will sometimes drink with a straw but I also like to eat with a spoon. The fluff creates a lot of volume too so it looks like you are getting a HUGE serving, but the calorie count is still the same!

Another fluffy shake!

Depending on the fruit, the shakes average in around 220-235 calories. Not too shabby for a milkshake huh?

Here is the nutritional info for a standard fluff: 220 calories, 3.1 grams of fat, 27.6 grams of carbs, 2.9 grams of dietary fiber, 15.6 grams of sugar (banana), 24-26 grams of protein (depending on the brand of whey)

    when you eat your shakes for breakfast do you eat anything else with them??

    1. Katie

      Yeah usually I do since they only come in around 230 cals, so I will do oatmeal or egg whites or something too!

    Can you taste the bananas in the fluff? I REALLY don’t like bananas (sad, I know) and I’m scared to try this recipe because of them. But I know it won’t be as fluffy and creamy without the bananas. Such a dilemma! Thanks!

    1. Katie

      If you add enough protein powder you cannot taste it at all! Try adding cocoa powder too to cover up the taste, or maybe some PB2 or peanut butter. You can also try adding just HALF of a banana!

      1. Kelsey

        Thanks! I’ll give it a try!

      2. Rebecca

        You can swap mangos for bananas which give the same creaminess, but I’d stick with a fruit flavor. Mango and chocolate sound like a strange combination.

    2. Kelda

      One trick I do is I use chocolate protein powder then add frozen cherries. You don’t taste banana at all and it’s like chocolate covered cherries. Or add cocoa powder like Katie suggested! Delicious and you get all the fluffiness from using the whole banana!

    3. Angela

      I use a tablespoon or two of sugar free jello pudding powder to my shakes sometimes no fruit at all makes it thicker expecially if i use greek yogurt too.

  4. Maisie

  6. Elizabeth

    I cant seem to get it to fluff??

    1. Katie

      the air helps, so are you doing it slowly? Also are you using a protein whey powder? because that is why it poofs up

  7. Susan

    would you send me a good brand name for the
    protein powder?

    1. Katie

      cellucor is good, and PEScience!

  8. Sheryl hazelett

    I am allergic to bananas. Most shakes I see have them. Is there a substitute?

    1. Katie

      Any fruit will help. I’ve used strawberries in the past and it worked well.

  9. Marlene

    Are these protein shakes considered a liquid diet? Can I lose weight using them?

    1. Katie

      They are just a substitute for a meal. I don’t recommend liquid diets.

  10. Lindsey

    This looks awesome! Do you need a food processor to make this? Or can you use a blender?

    1. Katie

      I use a blender or a food processor!

  11. Elaine

    You make those look yummy enough to try!!

    1. Katie

      They are so fluffy and good!

  12. Jean Gilchrest

    This was delicious! I usually can’t stand the taste of the protein powder. It totally masked the flavor!

    1. Katie

      Glad you love it. Years later and it’s still my go to!

  13. Cynthia

    I put bananas in a ziplock bag and mash them up and freeze. The frozen banana is what helps make it thick. I use protein powder as well,almond milk,spinach,kale and blueberries or some other frozen fruit. Just like a thick milkshake. I drink mine after a 4 mile walk,which counts as my lunch.

  14. LD

    This fluff is life!!! Saved me from eating cookies.

    1. Katie

      Haha I love fluffs too!

  15. Emma Watson

    I do this all the time! For a treat add a table spoon of peanut butter! Adds 4g of protien & is ridiculously good with chocolate flavoured protein powder 🙂

    1. Katie

      Thanks! I’m not too big on PB in my shakes though, I’d rather eat it off the spoon lol

  16. Carol

    Would the Quest protein powder work alright with the Fluff?

    1. Katie

      Yes! Makes it even fluffier because they have casein!

  17. Joyce

    Would muscle milk protein powder work in this also?

  18. Claire

    What kind of protein powder would you suggest? I haven’t had any luck with finding one that doesn’t taste like chalk! I also am in college so am looking for one that isn’t to expensive. Would love to gain some insight from the Skinny Minnie!!!

  19. Lori Nicholson

    I put pomengranate juice, blueberries and vanilla protein powder, it’s addicting!

  20. Monica

    I can’t eat anything that has tree nuts or peanut butter. Very allergic. What can be used in place of the almond milk.

  21. Sarah

    So delicious
    Was so fluffy

  22. Cayla

    A teaspoon of xantham gum really helps with the frosty like consistency. I got mine on Amazon!

  23. Jody

    What about pea protein? Allergic to dairy, whey is dairy.

  24. Donna

    Can you use 2% milk instead of almond milk?

  25. Beth

    I’m curious if I could use avocado instead of banana and still get a creamy consistancy with less sugar.

  26. Regan

    Can you use almond milk instead of vanilla almond milk? I normally just buy the unsweetned original ?

  27. Regan

    I made this with my protein powder and it was so good, but it was so filling and I didn’t end up eating dinner. How many servings is it?
