Double Chocolate Chunk
TL:DR
In 2 Sentences
A deeply chocolatey, uncoated bar that packs 20g of complete milk protein into just 170 calories with only about 1g of sugar—pulled off with a blend of fiber, sugar alcohols, and intense sweeteners.
When to choose Quest Nutrition Double Chocolate Chunk
Chocolate lovers who want a filling, lower-sugar, high-protein snack for post-workout or afternoon cravings—and who don’t mind a chewy texture or modern sweeteners.
What's in the Quest Nutrition bar?
Double Chocolate Chunk earns its name the straightforward way: unsweetened chocolate, cocoa processed with alkali, and cocoa butter build the rich cocoa profile, while almonds add a little crunch.
The protein backbone is decidedly dairy, using milk protein isolate and whey protein isolate (with a bit of sodium caseinate) to deliver a complete, low‑lactose punch that sits well above the category average.
Sweetness comes with very little sugar thanks to a modern blend—erythritol (a zero‑calorie sugar alcohol), stevia (plant‑derived but highly purified), and a touch of sucralose—plus polydextrose fiber and glycerin for chew.
Big picture: high protein, lean calories, and carbs that skew toward low‑impact fibers and sugar alcohols rather than flour or cane sugar—more engineered than “pantry‑only,” but designed for steady energy with a deeply chocolatey bite.

Protein
2015HIGHProtein comes from a milk‑based blend: milk protein isolate (mostly casein with some whey) and whey protein isolate, with a little sodium caseinate to help the bar hold together. That mix delivers complete, highly digestible amino acids with typically low lactose and a blend of slow‑ and fast‑digesting proteins. At 20 grams, it lands well above most bars without dragging in extra sugar.
Fat
79MIDMost of the fat is from cocoa butter and almonds. Cocoa butter leans toward stearic (a saturated fat that’s relatively neutral for LDL) and oleic (monounsaturated), while almonds add more heart‑friendly monounsaturates. There are no added seed oils here, so the fat profile is a chocolate‑and‑nut story—moderate overall and mostly coming from those whole‑food sources.
Carbs
2420MIDThese are largely “designed” carbs rather than flour or sugar: polydextrose (a manufactured prebiotic fiber) provides bulk, erythritol (a zero‑calorie sugar alcohol) supplies sweetness, and glycerin (a plant‑derived, syrupy humectant) keeps the bar soft. Together they tend to hit blood sugar more gently than regular sugar, offering steadier energy. A minority of people get GI rumblings from sugar alcohols or large fiber hits, so start with one bar and see how you feel.
Sugar
14LOWSugar is kept to about 1 gram; most sweetness comes from erythritol (a sugar alcohol that adds bulk with minimal calories) plus tiny amounts of stevia and sucralose (intense sweeteners). That keeps sugars low without fruit purees or syrups, though it does rely on highly refined sweeteners. If you’re sensitive to sugar alcohols or prefer to avoid artificial sweeteners, take note.
Calories
170210LOWCalories skew low for the category because most energy comes from protein and a modest amount of fat; much of the “carb” line is low‑calorie fiber or erythritol rather than starch or sugar. Roughly half the energy is protein‑driven, which helps with fullness without pushing total calories up. It’s a compact, chocolate‑forward bar that stays relatively lean.
Vitamins & Minerals
There’s no multivitamin blend here, but you do get about 10% Daily Value of calcium from the milk proteins and a modest bump of iron from cocoa. Potassium shows up in smaller amounts. Think of this as protein‑first with a little mineral bonus, not a vitamin vehicle.
Additives
You’ll see several functional additives: polydextrose for fiber and bulk, glycerin to keep moisture, lecithin (sunflower and/or soy) to help fats and water play nicely, and a sweetener system of erythritol, stevia, and sucralose. They’re effective, highly refined tools that create a chewy, low‑sugar bar. If you want a short, whole‑foods label, this isn’t it; if you want performance texture and low sugars, it fits the brief.

“I personally love the quest bars. They don’t really taste like the real thing, but they’re a reasonable facsimile. They are nicely soft and chewy and if any particular bar has icing, it is also on the bottom. They do have big chunks of chocolate in them, if applicable. If you’re a sweet tooth person who’s trying not to eat like an asshole these definitely scratch that itch. And a super high protein/calorie ratio for a bar like this. My favorites are Cookie Dough, Raspberry White Chocolate, Lemon Cake, Birthday Cake. Be aware that a lot of people do NOT agree on my picks though haha. Least favorites are the brownie and peanut butter chocolate. Kinda nasty. Best to grab a bunch of singles and give them a try and see which are for you. Also their peanut butter cups are BANGING and their cookies are really good. Just keep an eye on the nutrition facts”
“Quest bars are perfect. A goodly amount of protein in a tasty bar. I’m mad they quit making my favorite from years ago, peanut butter supreme. I don’t like the ones with chocolate coating as much. When I did Adkins I ate them daily. They are high quality.”
“I just want to express my love of them. I really look forward to them every morning like I would a muffin or brownie. I love them melted and I love them cold. I mostly love that they keep me full for hours and hours by some magical science probably called fiber. Who else agrees?”
Main Praise
Fans love that this flavor actually tastes like, well, chocolate—rich cocoa, real chocolate chunks, and a brownie-adjacent chew that feels substantial.
The macros are the headline: 20g of high-quality milk protein at 170 calories is a rare ratio, and it shows up in how full people feel; one Redditor even said it keeps them satisfied for hours.
Editors at mainstream outlets back that up, calling Quest one of the most filling picks because of the protein-plus-fiber duo. Texture-wise, supporters appreciate that it’s soft and chewy rather than chalky, with a cleaner bite than many coated bars.
And for many with a sweet tooth, it scratches the dessert itch without leaning on cane sugar.
Main Criticism
The very things that keep sugars down are the flashpoints: erythritol, stevia, and a touch of sucralose. A slice of reviewers notice a lingering sweetener aftertaste or a subtle "backnote" that reminds them it’s a protein bar.
A smaller but vocal group reports GI grumbling from sugar alcohols or large hits of refined fiber—if your stomach is sensitive, that’s worth testing. Texture can also be polarizing: chewy is satisfying to some and too tacky to others, and older bars can firm up uncomfortably if they’re past their prime.
Finally, it’s not a minimalist label—if you want only pantry ingredients, this is more performance-oriented than purist.
The Middle Ground
So which is it: candy-bar clever or lab-made letdown? The truth sits between.
If you enjoy a brownie-like chew and you’re comfortable with low-sugar sweeteners, Double Chocolate Chunk is a reliable win—filling, legitimately chocolatey, and efficient on calories for the protein you get. If sugar alcohols don’t love you back, or you’re hypersensitive to stevia/sucralose aftertastes, you’ll notice the engineering behind the flavor.
Texture divides the room, but part of the drama comes from freshness—several buyers found that older bars harden, so checking a best-by date wherever you pick them up is practical, not fussy.
And while The Guardian panned a coated Quest variant for being chalky and plasticky, this specific flavor is uncoated and tends to avoid that waxy shell feel. In short: fans want a functional, chocolate-forward protein hit; critics want a pastry.
Neither camp is wrong—they’re just shopping for different things.
What's the bottom line?
Quest Double Chocolate Chunk is a purpose-built, chocolate-first protein bar: 20g of complete dairy protein, 170 calories, and just about 1g of sugar, delivered via fiber and sugar alcohols in a dense, chewy format. It’s excellent for post-workout recovery or an afternoon holdover, especially if you like a brownie-like texture and prefer to avoid sugary syrups. The trade-offs are straightforward: modern sweeteners you can taste if you’re sensitive, a label that reads more “food science” than “farmers’ market,” and potential GI rumblings for a minority of people.
It’s also not for anyone avoiding dairy, almonds, or soy lecithin. Condensed listicle blurb: Deep cocoa, big protein, lean calories. Chewy and sweetener-forward in a way some love and others don’t; great if you want a low-sugar chocolate fix that actually fills you up—less great if sugar alcohols upset your stomach or you want a short, whole-foods ingredient list.
