FITCRUNCH
Peanut Butter Cookie
TL:DR
In 2 Sentences
A chef-made, six-layer style bar that truly eats like candy while delivering a whey-based 16g protein hit and only 1g of sugar, achieved with sugar alcohols and a highly engineered ingredient list.
When to choose FITCRUNCH Peanut Butter Cookie
Best for dessert-lovers who want a gluten-free, low-sugar protein snack after the gym or between meetings and don’t mind processed sweeteners; not ideal for those sensitive to sugar alcohols or for vegetarians (it contains bovine gelatin).
What's in the FITCRUNCH bar?
FITCRUNCH Peanut Butter Cookie leans into two things: classic peanutty comfort and a protein core anchored in whey.
The 16 grams of protein come primarily from a whey blend (isolate + concentrate), backed by soy protein isolate and a little sodium caseinate, while the peanut butter, peanut flour, and roasted peanuts drive the flavor.
Carbs sit on the lower end for bars, thanks to sugar alcohols and sucralose doing most of the sweetening, and the richer bite comes from palm‑based fats that give it that firm, candy‑bar texture.
If you’re looking for a low‑sugar, bakery‑style bar with mainstream protein quality, this is squarely in that lane—just know it’s built with a longer list of engineered sweeteners and emulsifiers rather than dates and oats.

Protein
1615MIDMost of the 16g of protein is delivered by a whey blend—whey protein isolate (low in lactose, fast‑digesting) plus whey protein concentrate—supported by soy protein isolate and a touch of sodium caseinate. That mix gives you complete, highly digestible protein with a quick hit from whey and a steadier trickle from casein, while peanut flour adds a small plant‑protein boost. It’s a dairy‑forward formula with solid quality, sitting a bit above average for protein among bars.
Fat
119MIDThe 11g of fat largely come from palm kernel oil and palm oil (also present in the peanut butter), which are more saturated and help create that firm, candy‑like bite. Peanuts/almonds and a bit of sunflower oil contribute unsaturated fats and vitamin E, but the palm sources still dominate the texture and fat profile. If you’re watching saturated fat, note the reliance on palm alongside the nut oils.
Carbs
1420LOWAt 14g, carbs are on the lower end for bars and skew toward engineered binders and sweeteners rather than whole‑grain bases. Sugar alcohols (maltitol and sorbitol) and glycerin keep the bar soft and sweet with fewer sugar calories, while small amounts of glucose syrup and maltodextrin add quick‑digesting bulk; there’s a little brown rice flour, but it’s not the star. Expect a smaller sugar spike than a sugar‑heavy bar, though some people feel digestive rumbling from polyols—start with one bar to gauge your comfort.
Sugar
14LOWSugar is low at 1g because sweetness is driven by sugar alcohols (maltitol, sorbitol) and a pinch of sucralose (a high‑intensity, zero‑calorie sweetener), not fruit or honey. There are tiny amounts of refined sugars (glucose syrup, dextrose, and sugar), but they’re not the primary sweeteners. That approach can blunt blood‑sugar spikes versus a syrup‑sweetened bar, though polyols may bother sensitive stomachs if you overdo it.
Calories
210210MIDAt 210 calories, this lands near the middle of the bar landscape, with most energy coming from fat (palm + nuts) and protein, and a smaller share from carbs. Because part of the sweetness comes from sugar alcohols, which carry fewer calories than sugar, the bar keeps sugars low without pushing calories sky‑high. It’s a compact, satiating snack rather than a carb‑heavy fuel bar.
Vitamins & Minerals
There aren’t standout vitamins or minerals over 10% Daily Value, but peanuts/almonds and sunflower oil naturally contribute a little vitamin E. You’ll also see “natural tocopherols” on the label—these are vitamin E compounds used mainly to protect oils from going rancid, not to fortify the bar. In short, this one is about macros and flavor, not micronutrient density.
Additives
This is a highly engineered bar: humectants (glycerin, sorbitol) keep it soft, sugar alcohols provide bulked sweetness, and multiple emulsifiers (mono‑ and diglycerides, acetylated monoglycerides, propylene glycol mono esters, lecithin) hold the texture together. Potassium sorbate helps with shelf life, and titanium dioxide is used for whitening—permitted in the U.S., though no longer allowed in EU foods. If you prefer very short, minimally processed labels, this won’t be your simplest option.

Range
“Just gotta toss a shout out for the Robert Irvine Fit Crunch bars. I just had a PB&J one for breakfast. Each bar has 30g of Protein. They taste really really good.”
“The Fit Crunch bars are great if you want something that tastes like a candy bar, but almost has the macros of a legit protein bar 190cals, 16g protein, 8g fat, 14g carbs”
“The Robert Irvine’s fit crunch bars. Just found these at Costco, they don’t spike me, and almost reminds me of Reese’s.”
Main Praise
Taste is the headline act. Across Reddit and Amazon, fans keep coming back to the candy-bar experience—some call it Reese’s-adjacent—and say it’s surprisingly satisfying for a low-sugar option.
The 16g of whey-based protein punches above its weight for a bar that feels indulgent, and many reviewers note it tides them over between meals without a sugar crash. Flavor consistency is another bright spot: even skeptical bar-eaters report that FITCRUNCH is the one they actually look forward to.
And for people managing sugar carefully, several users say it doesn’t spike them the way syrup-sweetened bars can.
Main Criticism
The trade-off for that taste is a long, very processed ingredient list, including multiple sugar alcohols and sucralose. Plenty of reviewers enjoy it with no issues, but a vocal minority—like Redditor Pixieflower—report stomach upset from polyols.
Others flag that 16g of protein feels a bit light for a bar that eats like a treat, wishing it were closer to 20g. There’s also the fat profile: palm-derived fats drive the texture and push saturated fat higher than nut oils alone would.
A few buyers describe an occasional artificial edge to the flavor and note the coating can melt in heat; texture also suffers if a bar has been stored poorly. Lastly, it’s not vegetarian (bovine gelatin), and the label includes titanium dioxide, which is allowed in the U.
S. but no longer permitted in EU foods.
The Middle Ground
So where does the truth land between “best-tasting bar ever” and “ingredient lab in a wrapper”? Probably in the middle.
If your top priority is joy-per-bite with a respectable protein boost, FITCRUNCH delivers—Redditor Checkers10160 nailed it calling it a candy bar’s cousin with legit macros. On the other hand, if you’re chasing a short, whole-foods label or your gut balks at sugar alcohols, Pixieflower’s cautionary tale may feel familiar.
About the protein: some commentary (like trainer reviews) argues only part of the 16g is “usable,” but whey protein is among the most digestible proteins available; for most people, 16g is meaningfully supportive of daily needs.
Calorie worries also need context: this specific bar sits at 210 calories—squarely snack territory—even though larger FITCRUNCH variants do run higher. The real fork in the road is philosophy: clean-and-simple or taste-and-texture?
If you’re in the latter camp and your digestion is cool with polyols, this bar is hard to beat for pure enjoyment.
What's the bottom line?
FITCRUNCH Peanut Butter Cookie is the rare bar that nails candy-bar pleasure and still shows up with 16g of whey-based protein, 1g of sugar, and gluten-free credentials. It’s tailor-made for the person who wants a sweet-feeling snack without the syrupy sugar crash. The compromises are clear: a long, highly engineered label; sugar alcohols that can bother some; palm-heavy fats; and no-go status for vegetarians.
If those don’t bother you, it’s an easy bar to keep in the bag for post-workout or afternoon save-me-from-the-vending-machine moments. If they do, you’ll find better fits in the whole-foods aisle.
Condensed pick for listicles: A candy-bar–level peanut butter cookie flavor with 16g of whey protein and just 1g sugar. Fantastic taste, but rely on sugar alcohols and palm oils—great for dessert-like satisfaction, not for sensitive stomachs or ingredient minimalists.
