Homemade Quest Bars

For those of you who have never heard of a Quest bar, they are one of the newest stars on the protein bar market.  The reason why everyone is raving over them is because they contain 20 grams of protein per bar, with almost 0 grams of sugar and packed full of fiber.

Often times, protein bars are simply just glorified candy bars because of all the added sugar required to make whey protein taste better.  Quest bars have managed to keep the high protein content, while keeping sugars low without compromising their great taste.

This isn’t to say that there isn’t any sweetness to them, it’s just that they use low/no calorie sweeteners.  The sugar substitute they use is called isomalto-oligosaccharide, which comes from starch and also contains lots of fiber.  In addition, they also use small amounts of sucralose (aka. Splenda).  These bars are great post-workout snacks that keep you full for a really long time.

While I love a Quest bar now and then, they are pretty pricey.  A box of 12 bars costs around $30, a price that I’m not willing to pay regularly.  However, recently I found a recipe that allows you to make your own homemade quest-like bars!

There are a few recipes that call for the isomalto-oligosaccharide, but I’m not willing to go hunting around for weird ingredients like that.  So instead, I am sharing this recipe below because it uses pretty simple ingredients and can be modified to a myriad of different flavours!


Homemade Quest Bars 

Makes 5 bars

Basic Ingredients

  • 4 Scoops of vanilla protein powder (about 1/3 cup a scoop)
  • 1/4 cup nut or seed butter of choice
  • 1/3 – 1/2 cup sweetener (like honey, agave, stevia, splenda, etc)
  • 4-6 tbsp. water (add tbsp by tbsp and judge consistency)
  • 1/4 cup oat flour or fiber powder or even ground flaxseeds (Omit for lower carbs, best with)


  • In a large bowl, combine the protein powder, oat flour (if using), nut butter and sweetener together. If using stevia / splenda, you’ll need more water than if using honey or agave.
  • Scoop out the dough, shape into 5 bars and add to a sheet lined with parchment paper, refrigerate for 30-40 minutes to firm up.

Per bar (varies with protein powder):


Fat: 8 

Protein: 20

Carbs: 11

Fiber: 5

Sugar: 2


  • Vanilla Almond Crunch: Use almond butter, a tsp of vanilla and some chopped almonds.
  • Cinnamon Roll: add 1/2 tbsp. cinnamon and 1 tsp vanilla
  • Chocolate Brownie: add 2 tbsp. cocoa powder and use chocolate protein powder (not necessary)
  • Lemon Cream Pie: Use sunflower butter and 1 tbsp. lemon juice
  • Chocolate Chip Cookie Dough: add 1/4 – 1/3 cup chocolate chip and don’t omit oat flour
  • Peanut Butter Supreme: use peanut butter.
  • PB & J: Use peanut butter and 3-4 tbsp. mashed or dehydrated strawberries or 2 tbsp. jam.
  • Coconut Cashew: Use cashew butter and 2-5 tbsp. coconut shreds
  • Chocolate Peanut Butter: Use chocolate protein powder and peanut butter
  • Mixed Berry Bliss: use 1 tbsp.  of each blue- rasp- black- and strawberries, mashed or dried.
  • White Chocolate Raspberry: Use 3-4 tbsp. mashed or dried raspberries or jam, and best with sunflower butter

Invent your own flavours and let me know in the comments which ones were your faves!  I personally love anything with peanut butter 😉

    1. These ones aren’t as chewy as the real quest bars, but that’s because they don’t contain that isomalto-oligosaccharide ingredient. You can actually find it online; its trade name is Vitafiber. But these ones are still pretty decent! 🙂

  1. OMG !!! I love them ! they were missing some fiber so I add some linseed to have something more similar to Quest bar nutritional information. Way cheaper than the original and way more natural

  2. Hi I was just wondering does the protein powder component make up 1/3 cup or 4 x 1/3 cup = 1 cup and 1/3 cup. My protein powder doesn’t come with a scoop so I can’t go by scoops. Thanks in anticipation!

  3. We made these tonight with Maria Emmerich’s homemade milk chocolate bars. A few things we noticed. Yes it required more water. We also found it better with a little more powdered xylitol and an extra scoop of protein powder. We also added vanilla to both batches (we only did 2, chocolate brownie with chocolate chunks and cookie dough). Hoping to make more later on and soon!

    1. Hi Beth, thanks for trying out the recipe and providing some feedback! I love hearing how people modify the recipe to make it their own unique treat!

  4. I have made these twice now! First time didn’t work out to well!! They kept falling apart and weren’t very good!!!! Second time I decided to add some coconut oil and. Vanilla extract they were much better!! They were chewy and so much flavour!!!!!

  5. I have found that oat flour and oat fiber cook VERY DIFFERENTLY! Kaitlyn, I’m curious as to which you use/prefer….and you other ladies too!

  6. Thank you for this awesome post!!!! these are amazing! I have made two variations so far and we love them! for those struggling with the powdering issue, i just added more waster till it became dough… its a sticky stinker though lol,

  7. Hi!! I just made these last night! The flavor is AMAZING! But mine are still gooey even after staying in the fridge all night. Do you know what I could have done wrong?

  8. These are so yummy! I made some with rhubarb jam & chopped white chocolate chips. I also made your cinnamon roll recipe, and added some pecans to it. Deee-lish!

  9. I had to put another two scoops of protein powder and some more oat flour into the mixture to make it stiff enough to handle. It is very sticky even yet. Next time I make these the water will be the last thing added

  10. My nephew eats the Oreo Quest bars and the Chocolate Chip Cookie Dough after his morning workouts. I’d like to try some homemade for him, but he’s allergic to peanuts/peanut butter. (I don’t know about other nuts.) Suggestions?

    1. You could try sunflower seed butter, tahini, or other nut-free butters that you can find in the organics section of a supermarket

  11. Do we need to use nut butter? Just asking because I ran out of almond butter and would still like to try them out 🙂

    Also, can oat flour be replaced with coconut flour?


  12. I used a mix of psyllium husk and ground LSA instead of oats for extra fibre. I also crushed and mixed in two sugar free chocolate digestive biscuits to make them like the chocolate chip cookie dough quest bars

  13. Can’t wait to try these! You can replace nut butter for sunflower seed butter. Never tried it, but my niece brings sunflower butter and jelly for lunch because of the nut allergies in her school.

  14. I am really interested in trying the strawberry cream cheese bar, but I don’t use cream cheese and don’t want to buy a whole container just for a few tablespoons. Do you think you could replace it with greek yogurt? (Or anything else?)

  15. We have made them 2 times with stevia but both times it’s so sticky it’s hard to get offl the wax paper any suggestions?

  16. No nasty aftertaste like some Quest flavors I have tried. I made mine with cashew butter, phylum husks, 1/4 c honey and 5 Tbs of water. I split the dough in half. Half I added PB2, water and raspberries. The other half I added raw walnuts and cinnamon. I baked one up for breakfast this am and it was like eating a cookie. Thank you for the recipe and saving me a TON of money! 🙂

  17. I love this, I used pure maple syrup for the sweetener, coconut flour for oat flour and added dark chocolate chips which makes it taste like cookie dough.

  18. When I put this in my fitness pal as separate ingredients with chocolate chips added, it says that 1 bar is 322 calories?! Not sure what I am doing wrong. I used:

    Protein powder
    Natural PB
    Ground flax seed
    Chocolate chips

  19. I made the strawberry cheesecake ones with pay fiber and they are very watery. I only used 1/4 cup water. I’ve added another scoop protein powder and a bit more oat fiber and they’re still runny. Amy suggestion how to fix them? Maybe some coconut flour?
