Peanut Butter & Jelly Quest Bar Review (New Corn Fiber Type)

All Quest Bars are made of high quality protein and have plenty of fiber, but these days that’s not enough. Food tech has advanced to the point that a nutrition bar must also be delicious to be called the best. So in this review I’ll let you know how the Peanut Butter & Jelly Quest Bar tastes, and what difference the new fiber type has made.

Peanut Butter & Jelly Quest Bar


The official description from Quest’s website:

The yummiest sandwich in history becomes a protein-rich Quest Bar with a taste that matches, bite for bite. 20g protein and 5g net carbs mean this is one sandwich you can carry in your pocket for nutritious anytime enjoyment.

It’s an uncoated, peanut and jelly-flavored protein bar with peanut pieces (and possibly almond—I couldn’t tell if all the almond was ground, or whether there were bigger bits, too). This is what it looks like:

Peanut Butter & Jelly Quest Bar, no wrapper

Taste & Texture

It’s sweet, softly chewy, with bits of nuts adding variety to the consistency. The peanut flavor is there, but the jelly element is most prominent. The jelly aspect is basically fruity, but I was unable to determine an exact flavor.

This is a really nice protein bar. Still, because the chocolate chip varieties are so delicious I normally choose them over it, and this one is relegated to the good-for-a-change category. But that’s more of a reflection of how excellent some of the other flavors are rather than this one being at all bad.

As with all Quest Bars it’s great as it is, but it’s even more rich and dessert-like heated about 10 seconds in a microwave or baked a few minutes (which is even better because the outside goes crispy).

Corn Fiber Recipe Update

Quest Nutrition built their reputation with IMO (isomaltooligosaccharide) fiber as a main ingredient in their bars. They’ve since removed IMO from their line up entirely and now use corn fiber instead, claiming it makes a softer, longer-lasting product.

The IMO version could get quite tough towards the end of the use-by date. The updated Peanut Butter & Jelly Quest Bar I had was noticeably softer, and the new fiber type seems to be a big improvement to the texture.

(Weights of Quest Bars can vary quite a bit, leading to significantly different caloric content than stated on the label. I did a write-up here.)

Peanut Butter & Jelly Quest Bar Rating: 8/10

This is a good flavor. As mentioned, just how good some of the other varieties are, and this being one of Quest’s slightly higher calorie bars, mean I normally choose other options, but I like this for something different.

Thanks so much for reading. If this was useful, I have reviews of all Quest Bars here.
