ONE Brands
HERSHEY'S Double Chocolate
TL:DR
In 2 Sentences
An official Hershey’s collaboration that delivers genuinely chocolatey flavor and candy-bar texture while keeping sugar to 1 gram and protein to 18 grams from high-quality milk proteins.
When to choose ONE Brands HERSHEY'S Double Chocolate
Best for chocolate-craving snackers who want a post-workout or afternoon pick-me-up that’s gluten-free, vegetarian, and low in sugar—provided you tolerate dairy and sugar alcohols.
What's in the ONE Brands bar?
This HERSHEY’S Double Chocolate collab from ONE Brands aims to taste like a candy aisle classic while performing like a protein snack. The chocolate character comes from a trio of cocoa processed with alkali (for a darker, smoother profile), natural cocoa, and real chocolate, rounded out by cocoa butter.
Under the hood, the 18 grams of protein land in the upper‑middle of the pack thanks to a blend of milk protein isolate, milk protein concentrate, and several whey proteins.
Carbs skew high for a protein bar (driven by refined bulking sweeteners and fiber syrups rather than oats or dates), while fat sits mid‑range and leans on palm oils and cocoa butter for that confectionery texture.
Sugar is strikingly low at 1 gram, which signals the sweetness is largely engineered with sugar alcohols and a tiny bit of artificial sweetener—great for keeping sugar down, but worth knowing if your stomach prefers simpler formulas.

Protein
1815MIDProtein here is dairy‑based: milk protein isolate and concentrate supply casein and whey together, while whey isolate, concentrate, and a hydrolyzed whey component round out the blend. That mix is cleanly made by filtration, delivers complete amino acids, and keeps lactose relatively low compared with milk—one reason it reaches a solid 18 grams (about the 63rd percentile among bars). If you tolerate dairy well, this is efficient, high‑quality protein; if you don’t, it’s still unmistakably milk‑derived.
Fat
99MIDMost of the 9 grams of fat come from palm kernel oil, palm oil, and cocoa butter—ingredients chosen to make a bar that snaps and melts like chocolate. That means a tilt toward saturated fats (palmitic from palm, stearic from cocoa butter) rather than heart‑healthy oils like olive or nuts. It’s a moderate fat load overall, but if you’re watching saturated fat specifically, this is more confectionery than nut‑butter bar.
Carbs
2520HIGHAt 25 grams (about the 80th percentile), the carbs are built from engineered sources rather than whole‑food staples: isomalto‑oligosaccharides and soluble corn fiber add bulk, maltitol (a sugar alcohol) and glycerin provide sweetness and softness, and a touch of tapioca starch, molasses, and caramelized sugar round out flavor. These choices generally blunt blood‑sugar spikes compared with straight sugar, but they’re still refined and can bother sensitive stomachs at higher intakes. Think steadier energy than a candy bar, yet not the slow‑burn you’d get from oats or dates.
Sugar
14LOWSugar is impressively low at 1 gram because sweetness comes primarily from maltitol (a lower‑glycemic sugar alcohol) plus a tiny boost of sucralose (an artificial sweetener), with small amounts of molasses and caramelized sugar for flavor. That keeps sugars down without making the bar taste austere, but it does mean a highly processed sweetening system. If you’re sensitive to sugar alcohols, consider how this fits with the rest of your day.
Calories
230210MIDCalories land at 230 (higher than average for bars), driven by the trio of protein, saturated fats, and the bulk from sugar alcohols and fiber syrups. Roughly speaking, protein and fat do a lot of the heavy lifting, with the remaining calories coming from those refined carb systems that aren’t sugar but aren’t calorie‑free either. The payoff is dessert‑like texture; the trade‑off is a bit more energy per bar.
Vitamins & Minerals
You’ll see about 10% of daily calcium, which naturally rides along with the milk‑derived proteins (milk protein isolate/concentrate and whey). Iron shows up at a modest level (around 8%) largely from cocoa and chocolate, with a small boost of potassium from the same sources—nice extras, though the bar isn’t fortified.
Additives
This is a modern, engineered bar: glycerin keeps it soft, soy lecithin helps chocolate disperse smoothly, maltitol and soluble fibers provide bulked sweetness, and sucralose adds a precise finishing sweetness at tiny doses. These are highly refined ingredients chosen for sweetness control, texture, and shelf life. Most people tolerate them fine, but sugar alcohols and some fiber syrups can cause gas or loose stools for sensitive folks, especially when combined with other similar products.

“i just had a ONE glazed maple donut bar and it was so good. i recommend if that’s your thing.”
“The maple glazed are amazing!!”
“I LOVE ONE BARSSS I converted because they don’t give me acid reflux on my run. I have one about 20-40min before and it’s just simply such a worry and pain-free run without being hungry or worrying about my burp bringing up a surprise. I love the maple glazed donut and birthday cake. Just got a variety box on Amazon to try the other flavors. They’re perfectly sweet, not too much not too little.”
Main Praise
Taste is the headline.
Across expert reviews, ONE is consistently praised for nailing flavor and texture in a way that feels like a treat rather than a chore, and this Hershey’s tie-in doubles down on that strength.
Men’s Health and Prevention have singled out the line as a smart post-workout option thanks to the protein-to-sugar math, and BarBend called ONE a favorite in taste tests. Real-world feedback backs it up: Amazon ratings hover around 4.
3 out of 5 across thousands of reviews, with plenty of “not sawdust” and “actually delicious” comments. Even on Reddit, where protein bars go to be roasted, you’ll find runners saying ONE bars sit well before a run and fans praising the sweetness balance.
The macro profile—18 grams of complete dairy protein, 230 calories, and just 1 gram of sugar—lands in that sweet spot for a satisfying snack that doesn’t blow up your day.
Main Criticism
Not everyone is smitten. A recurring theme in consumer chatter is texture: some find certain ONE bars dry, a little pasty, or distinctly “protein-y.
” Others point to the engineered sweetening system—maltitol and a touch of sucralose—as a potential gut irritant if you’re sensitive to sugar alcohols. Calorie counters sometimes note that, at 230 calories, ONE sits higher than some competitors in the 160–170 range, and cost can feel steep depending on where you buy.
Ingredient lists are longer and more processed than date-and-nut bars; if you’re after minimalism, this isn’t that.
The Middle Ground
Here’s the trade: to deliver recognizable Hershey’s-level chocolate with just 1 gram of sugar, ONE leans on fiber syrups and sugar alcohols for sweetness and texture. That choice creates the dessert-like bite many people love—but it also explains why a subset reports dryness or digestive grumbles.
The protein story is strong: 18 grams of milk-derived protein means complete amino acids and decent satiety, even if the line’s marquee flavors sometimes reach 20 grams while this collab lands slightly lower.
Reddit user takes range from “soap” and “dog food” (tough crowd) to “perfectly sweet” and “favorite bar,” which mostly underscores how personal texture and sweeteners are.
Compared with a whole-foods bar built on nuts and dates, this feels more confectionery; compared with a super-lean, lower-calorie bar, it tastes better to many but costs you some calories and a longer ingredient deck.
The truth sits in the middle: it’s a modern, engineered bar that prioritizes chocolate joy and sugar control, not purist simplicity.
What's the bottom line?
ONE Brands x HERSHEY’S Double Chocolate is a protein bar dressed like dessert: authentically chocolatey, satisfyingly chewy, and surprisingly restrained on sugar. chocolate craving shows up. It won’t win over minimal-ingredient purists, and if sugar alcohols bother your stomach, test with half a bar first.
But if you want a gluten-free, vegetarian, sweet-tooth-satisfying snack that behaves better than a candy bar, this collaboration hits the mark. Think of it as the chocolate bar that went to the weight room—and learned portion control.
