Double Chocolate Chunk 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 Double Chocolate Chunk Quest Bar tastes, and what difference the new fiber type has made.

The official description from Quest’s website:

Step One: Add Chocolate. Step Two: Add MORE Chocolate! Now add 20g of protein and what do you get? The Double Chocolate Chunk Quest Bar! And with 4g net carbs, this is a #CheatClean surprise that tastes as good as it is good for you!

It’s an uncoated chocolate protein bar with chocolate chunks interspersed. This is what it looks like:

Taste & Texture

It has a sweet, chocolatey, plain base, which is similar to the chocolate brownie flavor. However, the chocolate chunks in this make it incomparably better, adding a lot to both the overall flavor, and very pleasantly breaking up the texture of the chewy base.

The Double Chocolate Chunk Quest Bar is a perennial favorite—especially considering it’s one of the slightly lower calorie varieties (which is appreciated when dieting).

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). This flavor is especially fantastic heated because the chocolate melts, which makes for even more gooey richness.

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. In the Double Chocolate Chunk Quest Bar I’ve had variable textures in different boxes. The ones I had most recently were noticeably softer than the IMO version, but a box before that seemed about the same. Perhaps the previous box was mislabelled, I’m not sure.

(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.)

Double Chocolate Chunk Quest Bar Rating: 8/10

This is a great flavor, and I buy it regularly.
