Chunky Peanut Butter
TL:DR
In 2 Sentences
A rare combo: 20g of protein from a soy/casein/whey blend with 0g sugar and real peanut chunks for texture—gluten-free and decidedly peanut-forward.
When to choose think! Chunky Peanut Butter
Choose this bar if you want a dense, chewy, peanut-heavy snack that delivers post‑workout‑level protein, travels well, and you generally tolerate sugar alcohols.
What's in the think! bar?
think! Chunky Peanut Butter leans on a tri‑blend of soy protein isolate, calcium caseinate, and whey protein isolate to deliver a top‑tier 20g of protein without leaning on sugar.
Sweetness and chew come from an engineered mix—maltitol syrup (a sugar alcohol) and a bit of vegetable glycerin—while a touch of tapioca starch helps hold the bar together.
Fats sit in the middle ground, mostly from peanuts and peanut oil, with smaller contributions from sunflower oil, cocoa butter, and milk fat—so you get a mix of unsaturated and saturated fats.
As for the “chunky,” that’s the real peanut pieces and peanut flour doing the heavy lifting, with a bit of chocolate adding cocoa warmth. Below, we unpack how those ingredients shape the macros you see and what that means for energy, fullness, and comfort.

Protein
2015HIGHThe 20g of protein come from a blend of soy protein isolate plus dairy proteins—calcium/sodium caseinate and a little whey isolate—so you get a complete amino‑acid profile with both fast (whey) and slow (casein) digestion. It’s a refined mix, but quality is high, and the isolates keep lactose low even though it still contains milk. Net result: a near top‑of‑category protein hit that works well for recovery or a substantial snack.
Fat
109MIDFat is driven by peanuts and peanut oil (mostly monounsaturated), with supporting roles from sunflower oil and smaller amounts of cocoa butter and milk fat. That tilts the profile toward unsaturated fats while adding some saturated fat from the dairy and cocoa fats. It’s a moderate‑fat bar—enough to help with satiety without feeling overly heavy for most people.
Carbs
2320MIDThe carbs skew engineered rather than whole‑food: maltitol syrup (a sugar alcohol) and vegetable glycerin provide sweetness and softness, while a bit of tapioca starch acts as a refined binder. Polyols typically raise blood sugar less than table sugar, and the ample protein and fat help steady energy, though some people get GI rumbling from sugar alcohols. Expect steadier energy than a candy bar, but not the slow burn you’d get from oats or dates.
Sugar
04LOWThe label shows 0g sugar because the sweetness relies on maltitol syrup (a sugar alcohol) and a touch of glycerin rather than cane sugar—even with a little chocolate for cocoa notes. That generally means a smaller immediate glucose bump than a sugary bar, though maltitol still contributes calories and can nudge blood sugar modestly. If you’re sensitive to sugar alcohols, consider starting with half.
Calories
240210HIGHAt 240 calories, this sits in the higher‑snack/mini‑meal zone. Roughly a third comes from the 20g of protein (~80 calories), another chunk from the 10g of fat (~90), and the rest from the polyol‑heavy carb system—which carries slightly fewer calories than equivalent sweetness from sugar. It’s sized to bridge a long gap between meals or to bookend a workout.
Vitamins & Minerals
This isn’t a multivitamin bar. You get about 10% Daily Value of calcium from the milk proteins and a modest iron bump (around 8%) likely from cocoa and soy/peanuts, with most other micronutrients in trace amounts. Think protein and flavor first, not fortification.
Additives
To keep sweetness high and sugar low, the bar uses maltitol syrup and vegetable glycerin—highly refined sweeteners/humectants that mimic sugar’s body—plus a small amount of lecithin to keep the mixture stable. Natural flavor rounds out the peanut profile. It’s a typical low‑sugar bar playbook: functional and shelf‑stable, though more engineered than a simple fruit‑and‑nut bar.

Range
“I am eating think protein bars. Decent amount of protein (20g). Dont repulse me like so many out there”
“the Think high protein brownie crunch bar is honestly good if you want a different flavor, I found the one on the top to be pretty decent but defo think the brownie one is better”
“Chocolate brownie one was AMAZING!”
Main Praise
The throughline in praise is simple: this bar satisfies. Reviewers highlight a dense, chewy bite that reads “treat” without the sugar rush, with the Chunky/Crunchy Peanut Butter flavor often singled out by fans on Reddit as a favorite.
Editorial roundups back that up: SELF named the think! line a runner‑up overall for taste and satiety, while BarBend leaned into the candy‑like nostalgia that still delivers 20g of protein.
Amazon reviewers echo the staying power—several note it actually keeps them full—and one even uses half a bar to fuel a 12‑mile bike ride. Texture gets nods for being cohesive rather than chalky, and the macros are reliably consistent across the High Protein line, so you know what you’re getting when you grab one.
Main Criticism
The biggest knock is digestive: maltitol and friends don’t play nice with everyone. Some users report bloating or gas, especially if they down more than one bar.
Taste isn’t universally adored either—occasional comments mention a weird aftertaste or a drier chew on certain days. Allergens also narrow the audience: this is not soy‑free, peanut‑free, or dairy‑free, which sidelined at least one peanut‑butter‑loving Redditor with a soy allergy.
And while 240 calories is sensible for a mini meal, a few folks expecting a super‑low‑calorie bar find it heavier than the name suggests.
The Middle Ground
So where does the truth land?
If you want big, steady protein in a bar that actually tastes like peanut butter, this one succeeds more often than not—SELF and BarBend aren’t throwing around compliments lightly, and plenty of everyday eaters agree.
The texture invites repeat buys; one Redditor even praised the macros and taste in the same breath. But the sugar‑alcohol trade‑off is real: another commenter bluntly cited “foul gas,” which is both memorable and, for some, accurate.
That doesn’t make the bar “bad”; it just means your tolerance matters. Compared to a date‑sweetened bar, you’re swapping simpler ingredients and natural sugars for engineered sweetness that keeps sugar at 0g but may test your gut.
If you’re unsure, start with half a bar and water—that small tweak often decides whether this becomes your weekday staple or a once‑in‑a‑while grab.
What's the bottom line?
think! Chunky Peanut Butter is the definition of a purposeful protein bar: 20g of complete protein, a peanut‑forward chew, and no sugar on the label. It’s engineered, yes, but in service of taste and satiety more than novelty.
If you handle sugar alcohols well, it’s a reliable bridge between meals or a solid post‑workout bite that doesn’t taste like a compromise. If your stomach is sensitive, the very thing that enables the 0g sugar claim may be the deal‑breaker.
In that case, look for bars that sweeten with fruit or a modest amount of regular sugar and accept the trade of a few extra grams of sugar for better comfort. For everyone else who wants dense protein, real peanut pieces, and a familiar peanut‑chocolate profile, this bar delivers what it promises—and doesn’t repulse you while doing it, which in protein‑bar land is high praise.
