Quest Chocolate Chip Cookie Dough Protein Bar: 21g Protein, Labelgrade B+ (83/100)
B+ 83 / 100 — The benchmark for the 'engineered protein bar' category. 21g protein + 14g fiber + 1g sugar from a milk-protein-isolate + soluble-corn-fiber + erythritol/stevia/sucralose formula. Trade-offs: sucralose (Quest's mainstay), 12-ingredient panel, and saturated fat from cocoa butter.

Quest Chocolate Chip Cookie Dough delivers 21 g of protein, 14 g of fiber, and just 1 g of sugar in a 200-calorie, 60 g bar (USDA FDC 2629232). That works out to 35 g of protein per 100 g — about as protein-dense as a bar this size gets — and effectively zero added sugar. This is the bar the whole engineered-protein-bar category is measured against: Quest more or less defined the format of “candy-bar flavor, macros of a protein shake.” It earns a Labelgrade B+ (83/100), with perfect marks on protein density, fiber, and sugar. What keeps it out of the A range is the means to that end — a milk-protein-isolate base, soluble corn fiber, and a sweetener blend that includes sucralose.
Why the B+
| Dimension | Grade | Score | Why |
|---|---|---|---|
| Protein density | A+ | 100 / 100 | 35 g per 100 g — at the formula ceiling for the category |
| Fiber | A+ | 100 / 100 | 14 g per bar, almost unheard of for a bar — but it’s all soluble corn fiber |
| Sugar load | A+ | 100 / 100 | 1 g sugar (residual lactose), 0 g added sugar |
| Saturated fat | B- | 70 / 100 | 3 g per bar (5 g/100 g) from cocoa butter — moderate |
| Ingredient quality | B- | 70 / 100 | A dozen ingredients; sucralose and soluble corn fiber are the flags |
| Sodium load | C+ | 65 / 100 | 200 mg per bar (~333 mg/100 g) — the weakest dimension |
The pattern here is unusually clean: Quest aces every macro target a protein bar is supposed to hit, and the only real knocks are on how. Ingredient quality (B-) is the honest soft spot — the protein is a highly processed isolate and sucralose sits in the panel. Sodium (C+) is the other; 200 mg is forgettable in one bar but stacks fast if you treat these as daily fuel. Notably, the fiber “A+” comes with a footnote rather than a free pass: 14 g is a real number, but it’s engineered fiber, not whole-food fiber, and your gut may notice the difference.
The fiber is the whole trick
The headline math — 21 g carbs but only ~7 g net — runs entirely on soluble corn fiber, the second ingredient by weight. Subtract the 14 g of fiber from 21 g total carbohydrate and you get 7 g; subtract the erythritol too (a sugar alcohol the body doesn’t burn for energy) and Quest’s wrapper math lands near 4 g net carbs. Either way, only 1 g of the bar is actual sugar, and that’s residual lactose from the milk protein, not anything added.
This is the lever that makes the entire “low-sugar, high-protein, still tastes sweet” category possible, and it’s worth understanding rather than just trusting. Soluble corn fiber is a manufactured fiber the FDA recognizes as dietary fiber; some evidence suggests a mild prebiotic effect. The practical cost is tolerance. 14 g of soluble fiber in one sitting is a lot, and it’s the reason Quest bars are famous for being both extremely filling and, for some people, the cause of bloating — particularly at two bars a day (28 g), which pushes most people past comfortable. Great for satiety, occasionally rough on digestion. That trade is the bar in a nutshell.
Sweeteners: where the B- comes from
Quest sweetens this with three things working together. Erythritol does the heavy lifting — it’s the bulk sweetener, near-zero glycemic, and clean-tasting, which is why it appears high in the panel. Stevia and sucralose ride in the “less than 2%” tail to round out the sweetness erythritol alone can’t deliver (stevia turns bitter at higher doses; this is why it’s blended, not solo). The sucralose is the deciding factor in the ingredient-quality grade. It’s effective and it’s been Quest’s signature since day one, but it’s an artificial sweetener, and that’s exactly the line a whole-food-leaning shopper won’t cross. If that’s you, the honest move is a date-sweetened bar — you’ll trade away the low sugar to get an unprocessed label.
How it compares
Against the bars in our database it’s most often cross-shopped with, the contrast is stark — and it explains why “just eat a Quest” is the default answer:
| Product | Protein | Fiber | Sugar | Sweetener approach | Calories |
|---|---|---|---|---|---|
| Quest Cookie Dough (this bar, 60 g) | 21 g | 14 g | 1 g | Erythritol + stevia + sucralose | 200 |
| RXBAR Chocolate Chip (52 g) | 12 g | 5 g | 13 g (from dates) | None — whole food | 220 |
| Premier Protein Dark Chocolate Mint (72 g) | 30 g | 3 g | 10 g | Sugar + sucralose | 280 |
| Kind Fruit & Nut Delight (40 g) | 6 g | 3 g | 9 g | Honey | 200 |
Read it by the job you’re hiring the bar to do. Quest wins outright on protein-per-calorie and on sugar — 21 g of protein and 1 g of sugar for 200 calories is a combination none of the others touch. Premier packs more absolute protein (30 g) but spends 280 calories and 10 g of sugar to get there. RXBAR is the bar to reach for when you want a label you can read aloud, and you accept 13 g of sugar from dates and barely half the protein to get it. Kind isn’t really in this fight — at 6 g of protein it’s a nut-and-fruit snack wearing a bar wrapper.
Note on the rest of the lineup
This page is the standard 2.12 oz (60 g) Chocolate Chip Cookie Dough bar (UPC 888849000012). Quest’s classic line runs 20-plus flavors — Cookies & Cream, Birthday Cake, S’mores, and the rest — and the macros are nearly identical bar to bar (~21 g protein, ~14 g fiber, ~1 g sugar, ~200 cal), so this grade travels across the standard flavors. The exceptions worth flagging: Dipped bars add a chocolate coating and shift the macros, and Hero bars use a different protein blend with less fiber and a more candy-bar feel. If you’re buying one of those, read the actual wrapper — the numbers here won’t match.
Ingredients
Protein blend (milk protein isolate, whey protein isolate), soluble corn fiber, almonds, water, unsweetened chocolate, erythritol, natural flavors, cocoa butter.

Frequently Asked Questions
How much protein is in a Quest Chocolate Chip Cookie Dough bar?
21 g per 60 g bar (USDA FDC 2629232) — about 35 g per 100 g, which is roughly the ceiling for a bar this size. The protein is a milk protein isolate + whey protein isolate blend listed first by weight, so the 21 g is real dairy protein, not padded with collagen or gelatin the way some 'high-protein' bars are.
How can it have 21 g of carbs but only ~7 g net carbs?
Fiber. Of the 21 g total carbohydrate, 14 g is fiber (soluble corn fiber, the second ingredient by weight), leaving 7 g of non-fiber carbohydrate. Most of the remaining sweetness is erythritol, a sugar alcohol the body doesn't metabolize for energy — Quest and the keto community subtract it too, which is how the wrapper gets to a ~4 g 'net carb' figure. Only 1 g is actual sugar (residual lactose from the milk protein), and 0 g is added sugar.
What's the deal with 14 g of fiber — is that real fiber?
It's soluble corn fiber, which the FDA does recognize as a dietary fiber, but it's not the same as the fiber in oats or beans. It's the trick that makes the whole formula work: it adds bulk and the 'fiber' line without sugar or many usable calories. Some research points to a mild prebiotic benefit; the practical catch is GI tolerance. 14 g in one sitting is a lot of soluble fiber, and people who eat two bars in a day (28 g) commonly report bloating or loose stools.
What sweeteners does it use, and is there sucralose?
Three sweeteners: erythritol does the bulk of the work (near-zero glycemic, no aftertaste), with stevia leaf extract and sucralose in the 'less than 2%' tail. Yes, there's sucralose — it's been Quest's mainstay since the brand launched, and it's the single biggest reason this bar lands a B- on ingredient quality rather than higher. If you specifically avoid sucralose, this is the wrong bar; a date-based bar like RXBAR uses no artificial sweetener at all.
Does it actually taste like cookie dough?
It's the closest the Quest line gets. Real chocolate chips and chopped almonds are pressed into a dense, fudgy base, and Chocolate Chip Cookie Dough has been the flagship flavor for years. But manage expectations: it's a protein bar first. The texture is chewier and slightly chalkier than real dough, and the 14 g of fiber is what makes it that dense. It's a convincing approximation, not a dessert.
How does it compare to RXBAR or Kind?
They're not really the same product. Quest is engineered to maximize protein and minimize sugar: 21 g protein, 1 g sugar, sweetener blend. RXBAR Chocolate Chip is whole-food — egg whites and dates — at 12 g protein but 13 g natural sugar and no artificial sweeteners. Kind Fruit & Nut Delight is barely a protein product at 6 g, closer to a trail-mix snack. Quest wins decisively on protein-per-calorie and sugar; RXBAR wins on a label you can read; Kind isn't competing for the same job.
Is it keto-friendly?
Yes. After subtracting the 14 g of fiber and the erythritol, net carbs land around 4 g per bar — under the ≤5 g-per-snack threshold most keto frameworks use. The macro split helps too: 9 g of fat (3 g saturated, mostly cocoa butter) against only 1 g of sugar. It's one of the more keto-defensible bars on the shelf.
How much sodium is in it?
200 mg per bar, about 9% of the 2,300 mg daily limit. That's fine for one bar, but on a per-100 g basis it's ~333 mg — above the FDA's 140 mg/100 g 'low sodium' line. It earns a C+ here, the bar's weakest dimension after ingredient quality, and the number to watch if you're eating two or three a day.
Is it officially 'high in protein'?
Yes. 21 g is 42% of the FDA's 50 g Daily Value for protein, well past the 20% needed to make a 'high in protein' claim — which is why it's printed across the front of the wrapper.
