How I Created My Own High-Fiber Protein Powder

ingredients for a homemade high-fiber protein powder

(For a brief audio explanation of how this High-Fiber Protein Powder was created, listen to the Odds & Ends ending of The College Admissions Episode.)

I’ve been on the hunt for the perfect protein powder for years. In fact, just last season I recorded an entire episode of the podcast devoted to protein powders. You can listen to The Protein {Powder} Episode here OR simply open your podcast app where you’ll find it re-released as this week’s {wednesday rewind}. You’re welcome 🙂

I tried some really good ones. And some really not good ones.

The one thing they all had in common, though, is that they all lacked a substantial amount of fiber. And if you know me, you know there’s one thing I value as much, if not more, than I value protein and that’s FIBER.

Fiber keeps you feeling fuller longer, it lowers cholesterol, helps manage blood sugar levels, helps you “go” potty better and easier, and perhaps my favorite benefit — fiber functions as prebiotic fuel for a healthy gut. (Be sure to listen to The Probiotics & Prebiotics Episode).

Sure, there are protein powders that SAY they contain fiber. But seriously… 3 grams? Pssshhh… not even worth my time to scoop that out.

So when fellow dietitian Tanya Zuckerbrot recently launched her F-Factor 20/20 Protein Powder (the 20/20 stands for 20 g protein and 20 g fiber), I was super intrigued. I watched on Instagram as thousands of her fans posted pictures of yummy looking protein-packed, fiber-filled recipes, all made with her 20/20 protein powder. As a result, I quickly developed a serious case of fiber-FOMO and decided to purchase a bag of the 20/20 vanilla powder myself to give it a try.

The first thing I made with the powder was a High-Fiber Protein Waffle…

…and I immediately understood the hype. One serving made 3 VERY filling waffles that boasted more than 25 grams of protein and 22 grams of fiber just simply from using the 20/20 protein powder.

I was so blown away with how good the structure of these waffles turned out, that I immediately grabbed a different brand of protein powder out of my pantry to see if these “magic waffles” could be recreated with another powder.

I quickly learned they could not.

There was something special about all of the fiber in the 20/20 powder (it’s actually “hydrolyzed guar gum,” which is NOT the same a “guar gum”) that gave the powder enough structure to yield the perfect protein waffle. There was only one problem. The monk fruit sweetener used in the powder was NOT to my liking.

And so, my quest continued.

I started doing a little research and found that I could simply purchase the same type of fiber online and add it to the unflavored protein powder I already had on hand. (Thanks Cabot Creamery for hooking me up with so much whey protein!)

And so, I spent the last couple of months weighing and measuring to get just the right ratio of whey, fiber and erythritol (my preferred non-nutritive sweetener) to come up with my own Homemade High-Fiber Protein Powder recipe.

And today, I’m sharing it with you.

At $2.32/per serving, it’s an affordable way to boost both the protein in your diet and the fiber as well. While I’ve become a fan of using the one-serving recipe for the homemade high-fiber protein powder listed below in waffles, rest assured you can also use it anywhere you’d normally use protein powder, including in your favorite smoothie recipes. I added erythritol to the high-fiber protein powder recipe to sweeten up the powder enough such that you could simply mix it with water or milk and have a basic high-fiber protein smoothie. But if you wanted to use the powder in a recipe that called for additional sweetener, you could probably omit it. It’s really just a taste preference.

It’s also worth mentioning that I’ve been asked by more than one person if you could use another fiber in place of the hydrolyzed guar gum and the honest answer is, I dunno. I’m not sure you’d get the same structure to make things like waffles, pancakes, etc., OR that a different fiber in this amount would be as tolerable on the GI system. My personal opinion is if this works, why mess with success?

I hope you’ll give it a try and let me know what you think! ~Regan

(Note: I’ve probably made around 100 waffles using this recipe since I first created this homemade powder. Through much trial and error, I’ve tweaked the original High-Fiber, High-Protein Waffle Recipe to work best with my homemade high-fiber protein powder and have listed the recipe below.)


Homemade High-Fiber Protein Powder

ingredients for homemade high-fiber protein recipe

After years of searching for the perfect protein powder, I finally created my own Homemade High-Fiber Protein Powder using this surprisingly simple recipe.

  • Author: Regan Jones, RD
  • Yield: 1 serving



  1. Combine dry ingredients (whey, hydrolyzed guar gum and erythritol). When ready to prepare a smoothie, protein waffle/pancakes, etc., add vanilla extract for flavoring, if desired.  


*NOTE: Hydrolyzed guar gum and guar gum are NOT the same. Using “guar gum” (i.e. not labeled as hydrolyzed) will not yield the same results and may result in gastrointestinal distress. I recommend using the Nestle NutriSource Fiber Supplement as it’s the only fiber source I’ve tested with good results.

High-Fiber High-Protein Waffles

  • Author: Regan Jones, RD
  • Yield: 1 serving (3 waffles)


  • Cooking spray
  • 1 recipe of Homemade High-Fiber Protein Powder (listed above) OR F-Factor 20/20 Vanilla Protein Powder
  • 1/2 teaspoon baking powder
  • 1/2 cup liquid egg whites
  • 1 tablespoon water (optional)


  1. Preheat waffle maker to medium-low. (I use my Cuisinart Belgian Waffle Maker and turn it to Setting 3.)
  2. Coat waffle maker with cooking spray (waffles will stick if you skip this step.)
  3. Whisk together high-fiber protein powder and baking powder. Add liquid egg whites and whisk until smooth. Whisk in water if mixture is too thick. Let stand a minute to thicken while waffle maker preheats.
  4. Pour about 1/3 of waffle batter into center of waffle maker, being careful not to overfill. (This batter spreads during cooking and will overflow waffle maker if filled too full.) 
  5. Repeat with remaining batter. Serve waffles warm with syrup.

    This is great! Only problem is that the best nutrisource doesn’t seem to be available in Canada. Do you recommend something that can be purchased in Canada? Thank you 🙂

    • thisunmillenniallife on May 4, 2019 at 3:49 am

      Perhaps check to see if Sunfiber is available for purchase. I believe it’s the same type of fiber. Let me know if that helps!

        Yes found it! Thank you so much ❤️

    I was wondering if you could make these with whole eggs rather than egg whites? Thank you.

    • thisunmillenniallife on June 9, 2019 at 7:36 am

      Yes! I think it tastes a little more “eggy” when you use the whole egg, but I like it just as well 🙂

    You are amazing!! Thank you so much for this! Been playing around with a dupe but couldn’t find the right recipe. I am going to put this together ASAP!

    • thisunmillenniallife on June 17, 2019 at 1:03 pm

      I’m so glad you found this recipe 🙂 I worked on it for a while to get it just right. Let me know what you think!
