[2-Pack Review] Fiber One Chocolate and Key Lime Cheesecake Bars

This is a very personal review for me. I am a massive fan of Fiber One. I can’t really explain it, but I will eat (and have eaten) every Fiber One product under the sun. It’s probably the only brand I’ve consumed more than Oreos. And I’ve housed a lot of Oreos in my life–29 flavors and counting! Probably not something to brag about…

Part of what makes Fiber One products so appealing is that you can satisfy your sweet tooth with a decently portioned, lower-calorie snack. Plus, many of their products contain 20% of the recommended daily value of fiber per serving. Of course, that leads to an interesting game of Russian roulette when I just happen to eat an entire box of Fiber One cookies in one sitting.

200% of my daily fiber, just staring me in the face.

New this summer, Chocolate and Key Lime join Salted Caramel and Strawberry in Fiber One’s line of cheesecake bars. Each bar has 150 calories, 7 grams of fat, and 8 grams of sugar–a bit high for “healthy” foods, but still pretty good compared to other processed snacks.  No matter how you look at it, it’s still healthier than the alternative.

“The alternative” = eating half of a cheesecake solo

Fiber One’s existing cheesecake bars have a distinct texture, and these new ones are no different. Each bar has a soft, airy top layer atop a denser, crumbly bottom layer. It’s missing the creaminess of actual cheesecake, but for a snack bar, it’s good enough, I guess.

Fiber One Chocolate Cheesecake Bars have a surprisingly deep chocolate flavor. There’s an element of dark cocoa in the bottom “crust” layer, but the top layer contains a richer fudge-like taste. There’s a good amount of tanginess at play, too–cream cheese is the first ingredient listed in these bars–but it clashes with the complexity of the chocolate, and the result is this weird mix of flavors where none truly stands out. Ultimately, this bar struck me more as “chocolate cake” than “chocolate cheesecake.” Still, it’s a pretty good imitation of the dessert, especially for a Fiber One bar.


Fiber One Key Lime Cheesecake Bars have the same texture as the Chocolate variety (an almost spongy top layer and a firmer bottom layer), which is just as uninspiring. These bars, however, have a strong citrusy smell right when you open the wrapper. It’s not an artificial smell, either–these bars contain real lime juice, and that should hopefully bode well for their taste, too.

Sure enough, these Key Lime Bars have a distinct citrus flavor that slowly swells through each bite. It’s strong, but not overwhelming. There’s a great balance between sweetness and tartness here, too. Fiber One really nailed the Key lime flavor, which isn’t easy to do. The cream cheese (again, the first ingredient) seemed to work better in the Key Lime Bars, as it provided a creamy, tangy flavor to complement the bold Key lime taste. The bottom layer is pretty floury and not really graham flavored at all. It could be better, but it still provides that doughy crust-like element.

Overall, I was impressed with both new Fiber One Cheesecake Bar flavors. The Chocolate variety falls a bit short of truly capturing the taste of chocolate cheesecake, but the Key Lime flavor is a convincing recreation of Key lime cheesecake. The Key Lime Cheesecake Bars are a fun summer flavor for a midday snack or post-workout treat, but you really can’t go wrong either way. If you’ll excuse me, I’m off to crush the remaining 160% daily value of fiber in these two boxes. Wish me luck. ?

In a Nutshell: Chocolate flavor has elements of cocoa, fudge, and cream cheese, but they clash too much to be fully enjoyed. Key Lime flavor is great, achieving a natural balance of sweetness and tartness, along with a tangy cream cheese factor. Today will go down in history as the first time I ended a review with a poop emoji.
Overall Score: Chocolate: 7 out of 10

  1. Chocolate and acid never really go together very well but the chocolate bars are as close as you’re going to get to the best possible outcome to it.

    The key lime bars were a very dirty lime, not really key lime and very lacking on cream. I ate the box I bought but won’t be buying again.

    I felt both varieties were a huge drop off from the caramel and strawberry bars. Where’s my center lane of chocolate and lime filling?!

    I eat entirely too many Fiber One bars (Cinnamon Crumb is still the hands down best by a huge margin) – I would say these aren’t even the top half if you ranked them.

    1. A fellow Fiber One enthusiast! I wasn’t quite as low on these, but I agree that the previous cheesecake flavors set a pretty high bar. Hopefully we see the return of the filling stripe with their next flavors!
