Homemade “Quest” Protein Bars

So I LOVE the taste the (most of) Quest Nutrition Protein Bars, particularly Double Chocolate Chunk, Cookie Dough, and Peanut Butter. But I have to say it is a pain having to order them all of time. Also at $25 for a box of 12 they are not exactly cheap. However, I must note that I don’t think this is crazy expensive either as it is in line with many other leading brands of  protein bars out there. But, needless to say, I thought to myself there has to be a way to make a version of these Quest bars myself. And that way, I could add whatever I wanted and I would know exactly what was in them. So of course I Googled it , because….well….that’s what we do, we Google it! 🙂

There are a TON of videos and posts of there about how to make your own “Quest” bars. I tried many of them. Many. Of. Them.

And finally, after all my trials and errors (and there were many!) I came up with 2 perfect base homemade Quest protein bar recipes. Both recipes have 3 ingredients, protein powder , peanut butter, and VitaFiber.

  1. Protein Powder – Not all are created equal. I have found that the Quest Peanut Butter flavor protein powder is the best. It is the perfect consistency powder to make bars out of. The best part is that the peanut butter flavored protein powder is great because there are some many different things you can add in to change it up. You can try different brands until you find one you like, but I really recommend this one.
  2. Peanut Butter- I prefer Creamy Jiff. You can use any brand you wnat, but note I have not made these with natural types  (you know where the oil is on top) and so cannot say how that will work.
  3. VitaFiber – (IMO – isomalto-oligosaccharide) is syrup-like low calorie, high fiber sweetener that is used in actual Quest bars. Or at least it used to be, now they seem to be making it with corn syrup instead. But I am not going to get into a long explanation of what it is because this is probably not the first post you have read about it. I am also not going to go into the argument of the fiber and whether it counts as “fiber” or not. You can go here to check it out if you want. Needless to say you need it to make a the perfect bar consistency and can buy it here on Amazon. Be sure to get the Vitafiber SYRUP and not the powder!


The first base recipe is what I use when I am going to add in extras to the bar, such as chocolate chips, fruit bits, etc.

BASE RECIPE 1 – For when adding in extras.

(Nutrition – Calories: 202, Fat: 4.8g, Protein: 20.8g, Fiber: 25.8g, Carbs: 31.7g)
• 7 teaspoons (35g) Vitafiber
• 25g protein powder
• 1/2 Tablespoon Peanut Butter


• Ghirardelli 60% dark chocolate chips (I use 6 chips in each bar)
• Peanut Butter Chips
• Oreos
• Peanuts
• Chocolate covered peanuts
• Fruit Jam of choice
• Banana Chips
• Flavored extract, such as raspberry or strawberry
• Anything else you can think up!


This second recipe is for when you want a plain peanut butter bar, which I have to say is my favorite! It uses a teaspoon less of the Vitafiber and 1/4 tablespoon more Jiff, so it’s really got a nice peanut-buttery flavor. Yummy!

BASE RECIPE 2 – For when making a plain peanut protein butter bar with no extras.

(Nutrition – Calories: 217, Fat: 6.8g, Protein: 21.7g, Fiber: 22.6g, Carbs: 28.7g)
• 6 teaspoons (35g) Vitafiber
• 25g protein powder
• 3/4 Tablespoon Peanut Butter



My instructions below tell you how to make them with or without extras. The pictures included show me making them with Ghirardelli Chocolate Chips. You need a silicone baking pan of any shape you desire. Mine is a muffin one. I like to quadruple the ingredients and make 4 at a time. 🙂

One thing to keep in mind, you have to have everything measured out in bowls and ready to go BEFORE you start because you have to put this together very quickly before the vitafiber hardens. 

1. Heat the Vitafiber in a small saucepan until it starts to bubble, about 30 sec – 1 min.
2. Immediately remove from heat.
3. Immediately add in the Peanut Butter and mix it around until melted in.
4. Immediately add the protein powder and vigorously stir it until it is incorporated. (It will look like the picture below. It will be kind of dry looking, but it is fine.)

5. Then add in any UN-MELTABLE extras and stir that in gently. If you are using something that is meltable, such as chocolate, jam, etc you will want to add it to the mixture in small increments.
6. If not adding any extras – Immediately press the mixture into a silicone pan, either a bar pan or a muffin pan depending on what shape you want it to be. If adding MELTABLE extras – Press only half of the mixture into a silicone pan, add in your extras, then add the rest on top and press it down using firm pressure.

7. Remove from the silicone pan, and holding it in your hands kind of cup it in your hands and firmly press it together so it is solid. Then set it on a clean counter and press down to flatten it slightly.

8. Refrigerate for 1 hour, then remove from fridge. I keep mine in  Tupperware on the counter as I like them room temperature.
