Healthy Nutella Fudge DIY Protein Bars

Healthy Nutella Fudge Protein Bars (sugar free, low fat, gluten free, vegan) - Healthy Dessert Recipes at Desserts with Benefits

Need a quick breakfast/snack on the go?  Make these (secretly) Healthy Nutella Fudge DIY Protein Bars!  They’re no-bake, easy to make, and super fudgy and sweet.  You’d never know they’re sugar free, low fat, whole grain, gluten free and vegan!

My Healthy Homemade Nutella makes these super decadent protein bars as guilt-free as possible so you can feel good about eating them.  You can have all the taste of storebought Nutella but without all the nasty ingredients.

These are for serious chocolate lovers only  😉

You could also serve these protein bars as little cubes of fudge, just slice each protein bar into three or four.  Kind of like what I did with my Red Velvet Fudge.

These Healthy Nutella Fudge DIY Protein Bars are super healthy, packed with healthy fats, fiber, complex carbs and high-quality protein.  Yeah, I’ll take twenty.

You must make these protein bars as soon as you step foot inside your kitchen!  You will have quick and easy snacks all ready for you for the entire week!  If they last that long…

All by myself, these lasted me three days (there is NO such thing as taking things slowly).  I took them to school with me to snack in between classes.  So glad I did, they brought a huge smile to my face 😀

One protein bar for before my exam (for concentration, fuel and energy…  and a reward for all that studying!) and a protein bar for after my exam (as a post-exam reward, duhhh)

These protein bars keep very well in the fridge, but I wonder how long this chocolate-hazelnut goodness will last in YOUR home…

  1. I just went out and got the ingredients I’ll need for your other protein bars. I guess I’ll just have to add more to my list for the next trip I make! These look fantastic!

  2. OK this post could NOT have better timing! i just finished up a batch of protein bars! I made these and now they’re in the fridge, based on the dough taste they’re prettty darn good 🙂

  3. I absulutely agree that your fudge is healthier than normal fudge. BUT, if you want to compare them, you should do so for the same amount. The serving of the normal fundge (105g is the sum of nutrients in the table) is cca three times as big as in your recepe (55g, 30g of nutrients in the table). This way its a bit unfair…

    • Eliska-
      I understand what you’re saying, but the nutrition labels are actually for the same amount. Both recipes use 8×8 inch pans, so 1/10th of the final product will both be the same size 🙂
      I didn’t make the nutrition labels by weight because the Nutella fudge recipe is cooked on the stove. The cooking process causes water to evaporate and the total weight to decrease.

  4. These look interesting, I’ve never seen vegan fudge made with oat flour before! I’ve tried vegan “fudges” before and not been entirely satisfied with the too-soft texture; these look as though they have a bit more firmness and bite to them:) Will have to try… would it be possible to make these with regular cocoa powder instead of protein powder? Obviously the protein won’t be there, but that stuff is just so expensive xD

    • Shonalika-
      These protein bars are soft and fudgy, but they still hold their shape when you bite into them 🙂
      As for the cocoa powder, I’m afraid that won’t work. Cocoa powder is very bitter and the protein bars will have an overpowering bitter chocolate taste. The protein powder acts as a binder (it absorbs a lot of liquid), adds flavor and provides structure.
      Here is a cheaper brown rice protein powder:

      I’ve tried this brand in vanilla and it’s pretty similar to SunWarrior!
      Hope you get to try the recipe 🙂

  5. Aha, I live in the UK so the shipping costs might just cancel out the cheapness there – thanks though XD

    Still, I wanted to try chocolate protein powder at some point anyway, as a lot of people mention/use it and I’m curious – I’ll wait till I do eventually get some locally and then give this recipe a shot:)

  6. LOVE IT! I love how it has healthy benefits yet a decadence dessert flavor or nutella fudge!

  9. You are deadset my dream girl…. Marry me forever haha.

  10. WOW! Cannot wait to make these. Would a chocolate pea protein work well? I have the Vital one that I don’t use anymore and thought I could utilise it making stacks of these!!

    • Adelina-
      Hmmm, I haven’t tried using pea protein so I can’t be sure. Although, most vegan protein powders seem to work similarly — they all absorb a lot of liquid and seem to give off the same texture.
      If you give it a shot, I hope the recipe works out and that the protein bars taste DELICIOUS! 😀

  11. I just stumbled across this site yesterday and I’m completely obsessed. I’ve already purchased two products from your links and will doubtless get more as I try more recipes.

    Question regarding the vanilla flavored Stevia: could one not add actual vanilla/extract/paste to the protein bars and stick with the unflavored Stevia? I’m a vanilla fanatic (I’m making your homemade paste tomorrow) and much prefer to stick with the bean rather than flavorings.

    • Liv-
      I’m so glad you found my blog!! You can definitely substitute the 1 tsp vanilla-flavored stevia with 1 tsp of regular stevia + 1/2 tsp vanilla paste.
      If you’re a vanilla fanatic, go ahead and up the paste to 1 tsp or use the beans from about 1/2 a real vanilla bean pod 🙂
      Hope you like the protein bars!

  12. Thank you! I think I’ll use the beans themselves since the paste will add some sweetness.

    On an unrelated note, do you take challenges? Because I would dearly love to see you take on the greatness that is the Amaretti di Saronno cookie. Replicating that miraculous crunchy texture is a difficult task even using traditional ingredients. Only your diligence, fearlessness and stubborn refusal to settle for second best could make the magic happen with healthier ingredients.

  13. Hi there! Just wondering about possibly substituting the oat flour for coconut flour, will that work??

    • Matt-
      In my experience, coconut flour absorbs A TON of water… especially compared to oat flour. I have no idea how or why (probably the fiber?), so I don’t think it would work in this recipe. If you are looking for a low carb sub you can try using almond flour instead 🙂
      The texture might not be the same or hold up as well compared to the original recipe, but I think it will work just fine!
      Hope you like the recipe!

  16. Thank you so much for sharing, Jessica!! 🙂

    I’m a huuuge Nutella fan and I like some protein enhanced snacks, so this is the PERFECT combination for me.
    Love your recipe to make Nutella all from scratch too!

  17. What can I substitute the stevia for? Preferably agave or regular sugar. I can’t have stevia, Splenda or other synthetics. Thanks so much!!

    • Sherice-
      I’m afraid there isn’t a good substitution for the stevia. The stevia extract I use isn’t synthetic, it’s all-natural and organic (unlike Splenda).
      1 tsp of stevia has the sweetness of about 1 cup of sugar, and the vanilla-flavored version adds some flavor as well.
      If you don’t mind trying some recipe testing in your kitchen, I would recommend replacing the stevia with 2/3 cup of organic agave nectar. You will also need to add another ~1/3 cup of oat flour and ~1 scoop of the brown rice protein powder to balance out the extra liquid from the agave 🙂
      I hope these subs work out for you, and I hope you like the protein bars!!

  19. Would love to make these – I have egg white protein … would that work? Thanks! OH, and the homemade Nutella? My daughter is indebted to you for life! Thank you!

    • Jackie-
      No problem!! I hope you guys like the Homemade Nutella recipe!! 🙂
      Though, I’m afraid the egg white protein powder won’t work in these protein bars. Only vegan protein powders work for some reason? I only use brown rice protein powder because I find that it has the best flavor and texture.
      For some reason, whey, casein and egg white protein powders make the protein “dough” super gooey and sticky. They don’t solidify 🙁

  20. Can you suggest an alternate to the stevia, himalayan salt, and maybe the oat flour? I know, sounds crazy,but hear me out. These sound like a nice thing to try making at the Home I work at, but my budget’s only so big, and it’s hard to justify such pricey ingredients

    • PC-
      I totally understand! Thankfully, the Pink Himalayan Salt can be substituted with regular salt, and the oat flour is simply ground up oats… a pretty inexpensive ingredient 🙂
      Just put about a cup of oats in a blender or food processor and blend until flour-like.
      Unfortunately, there isn’t a substitute for the stevia. It isn’t that expensive since it’s 100% organic and you only use a small amount at a time.
      I hope you like the recipe!

  21. I just looked through the comments and found my mistake: DO NOT USE ANY OTHER PROTEIN POWDER.

    I ended up wasting a lot of ingredients to only end up with (tasty) brownie batter-like sludge. Kind of bummed!

    I’ll have to get brown rice protein powder and try again.

    • Devyn-
      Oh no! Sorry about that, I’ll update the recipe to give readers a little warning about other protein powders.
      (I tried using whey in these protein bars once and all I got was Nutella “goo”)
      If you try the recipe again using brown rice protein powder, I hope you love em!! 🙂

      • I came back to look at this site and realized I had commented on this. Thank you so much for editing the recipe a bit to make it more obvious that Whey is a “no-no.” You’re awesome!

  22. Why can’t you use whey protein for this recipe? What does it do to the final product texture? These look fantastic btw! Thank you for sharing all your recipes!

    • Mandy-
      I’m afraid whey protein just doesn’t work 🙁
      For some reason the bars don’t solidify and the dough turns all gooey and sticky. I’ve tried making this recipe with whey so many times and each time it’s a complete fail!
      Brown rice protein powder is the magic ingredient here 🙂

  23. I can’t wait to make them, they look fantastic!!! I live in Romania and here I could find only unflavored brown rice protein. Do you think I could use it instead and flavor it with coco powder or just with chocolate extract?

    • Tatiana-
      Unflavored brown rice protein will work just fine! But you’ll definitely need to add some more cocoa powder and some sweetener. I’d say about 1 tablespoon of cocoa powder and ~20 drops more of the stevia extract (or you can use a packeted sweetener, like Truvia or stevia… about 2-4 packets).
      I hope you like the recipe Tatiana! 🙂

  24. Could you use natural peanut butter in place of the homemade Nutella?

  25. Jess, I replaced the nutella with 2 tbls natural peanut butter and 4 tbls PB2…. and I did half almond flour mixed with the oat flour. I also added 1/4 cup of all natural honey (I have an insane sweet tooth!). They turned out great! Seriously tastes like peanut butter fudge. My bars were 169 calories and 15.7 grams protein. SUCCESS!!!! Thank you so much for the recipe.

  26. Karine Gosselin

    Hello !!! Love your site !
    Can I use chocolate soy protein powder ? thank you 🙂

    • Karine Gosselin-
      Thank you so much!! I haven’t tried this recipe with soy protein powder so I can’t be sure, but I think it might work 🙂
      All I know is that whey, casein and egg proteins DO NOT work… at all 🙁
      I’m crossing my fingers the substitution works out for you!!

  27. Why no whey protein?

  28. I really want to make these and I only have whey!!! 🙁
    Just wondering, for when I need to stock up on protein powders again, what are your views on the best ones? Are there any benefits, health, taste or performance wise, of vegan over whey?
    I might get brown rice protein just so I can make these!! haha Haven’t seen any in the shops in the UK though, maybe just because I wasn’t looking for it!

    So happy I found your site!!

    • Chloë-
      I’m so glad you found my blog too! 🙂
      I think all protein powders are definitely good to keep around as supplements and for recipes such as this 😉
      Whey is easily digested and the protein has a higher bioavailability compared to brown rice protein. I prefer the taste/texture of whey, but whey just doesn’t work in a lot of recipes 🙁
      One thing to keep in mind when you’re buying whey is to buy all-natural! I used to get Optimum Nutrition which has sucralose and artificial ingredients… and then the “natural” one has added sugar. I also took a university course on cows and cow farming practices from an actual member of MONSANTO, just so I could learn the dirty details. For this reason, I only buy organic, grass-fed whey now (the class really horrified me… the teacher was all FOR pumping cows full of hormones!).
      I haven’t bought this whey yet, but it’s in my Amazon shopping cart for when I want to make some recipes with whey (it’s organic, grass-fed and pretty cheap compared to others):
      My favorite brown rice protein is SunWarrior, although there are cheaper brands out there:
      Also, protein powder is much cheaper online (I save about $10 PER package by buying online). I hope this helps Chloë!

  29. This sounds awesome!!! However what can I do to substitute the vanilla flavored stevia? It doesn’t ship to Canada ): and I have no idea where I could pick it up here.

  30. Hi love the recipe but one question, why not use whey protein? That’s all I have…thanks.
