Perfect Keto Collagen Protein Bar Cookie Dough is my pick for most people. It has 4g net carbs without a sugar alcohol deduction, 11g protein and almond butter as its first ingredient. I’d look at Quest for more protein, or Munk Pack for plant protein with separately listed allulose.
These are nutrition and ingredient comparisons as of October 24, 2026, with no taste ratings. Net carbs here means total carbs minus fiber, with erythritol or allulose subtracted where the label identifies the amount; think! lists erythritol as its only sugar alcohol. Glycerin and maltitol stay in the count. Labels change, so check the package before buying.
Compare the labels
All figures are per bar. Carbs means total carbohydrate, before deductions.
| Product | Serving | Calories | Fat | Carbs | Fiber | Protein | Calculated net carbs |
|---|---|---|---|---|---|---|---|
| Quest Chocolate Chip Cookie Dough | 1 bar (60g) | 190 | 9g | 22g | 12g | 21g | 4g subtracting sugar alcohol line; 10g counting it |
| Perfect Keto Cookie Dough | 1 bar (45g) | 230 | 18g | 12g | 8g | 11g | 4g |
| think! Delight Chocolate Peanut Butter Pie | 1 bar | 180 | 14g | 14g | 3g | 10g | 4g |
| Munk Pack Peanut Butter Cup | 1 bar (57g) | 210 | 14g | 22g | 6g | 15g | 5g |
| No Cow Peanut Butter Chocolate Chip | 1 bar (60g) | 210 | 5g | 27g | 16g | 20g | 4g subtracting sugar alcohol line; 11g counting it |
Quest’s 6g sugar alcohol line and No Cow’s 7g line don’t separate erythritol from glycerin, so choose Perfect Keto, think! or Munk Pack if you need a firm 5g cap. The two counts show the result with the whole sugar alcohol line deducted and with none of it deducted.
The five picks
Quest Chocolate Chip Cookie Dough: most protein
Quest’s brand label lists 21g protein in a 60g bar, the highest protein amount here. It supplies 190 calories and 9g fat. The protein blend is milk protein isolate and whey protein isolate; almonds and unsweetened chocolate also appear in the ingredients.
Most of its listed fiber is polydextrose. Sweeteners include erythritol, stevia and sucralose. The label declares milk, almonds and soy. This is the protein-first choice in the group, with more protein than either of the plant options. If avoiding sucralose is a priority, Perfect Keto uses monk fruit and stevia instead.
Perfect Keto Cookie Dough: best overall
The Cookie Dough label gives 12g total carbs minus 8g fiber, or 4g net. It lists 230 calories, 18g fat and 11g protein per 45g bar, with no added sugar or sugar alcohols.
Almond butter, soluble tapioca fiber and bovine collagen peptides lead the ingredients. It also contains coconut-derived MCT ingredients and uses monk fruit and stevia. This is my straightforward choice for carb accounting, though it doesn’t match the protein in Quest or No Cow. The collagen also rules it out for anyone avoiding animal ingredients.
think! Delight Chocolate Peanut Butter Pie: clear erythritol math
The think! brand panel lists 14g carbs, 3g fiber and 7g sugar alcohols. Erythritol is the only sugar alcohol in the ingredients, so the calculation is 14 minus 3 minus 7, giving 4g net.
It has 180 calories, 14g fat and 10g protein per bar. Peanuts come first, followed by erythritol; whey and milk protein isolates and chicory root fiber also feature. Milk, peanut and soy are declared allergens. It meets the protein minimum for this list exactly. Don’t mistake the protein-bar name for a larger protein serving.
Munk Pack Peanut Butter Cup: best allulose option
Munk Pack’s Peanut Butter Cup label lists 22g carbs, 6g fiber, 11g allulose and 1g glycerin. Subtracting fiber and allulose gives 5g net carbs. The wrapper’s 4g claim also requires deducting glycerin, which stays in the count here.
The 57g bar has 210 calories, 14g fat and 15g protein from a blend including soy, peanut, fava and pumpkin seed proteins. Allulose and monk fruit provide sweetness. I’d choose it for plant protein without erythritol, rather than the Probiotic wording on the wrapper. Its allergen statement lists peanuts, cashews, almonds and soy.
No Cow Peanut Butter Chocolate Chip: most plant protein
No Cow’s label image lists 20g protein, 210 calories and 5g fat per 60g bar. Brown rice and pea proteins supply the protein, while soluble corn fiber accounts for much of its 16g fiber.
The ingredients include peanuts, chocolate chips, erythritol and stevia leaf Reb M. Glycerine appears third. This is the higher-protein plant option among these picks. Its fiber comes largely from an added ingredient, rather than whole nuts, so the short name on the wrapper doesn’t tell you the whole story. Read the ingredient list if you’re choosing between it and Munk Pack.
How to choose a keto bar
Start with the calculation
For a low-carb protein snack, I look for at most 5g net carbs and at least 10g protein per bar. “Net carbs” isn’t an official FDA term, so read the ingredients and deductions instead of trusting the front wrapper.
FDA guidance on allulose says it remains part of total carbohydrate. That’s why Munk Pack needs an allulose deduction. Perfect Keto needs only fiber subtracted. Same shopping category, different arithmetic.
Read the sweetener and protein sources
These bars use added fibers such as polydextrose, soluble corn fiber, tapioca fiber and chicory root fiber. Use the dietary fiber amount on the label when doing the subtraction. Then check where the protein comes from: milk, collagen and plant blends suit different shopping priorities.
A bar’s protein total also needs some context. Perfect Keto has less protein than Quest, but it skips sugar alcohols. No Cow has more plant protein than Munk Pack, while Munk Pack skips erythritol. Pick the trade-off you care about before stocking a drawer with a whole box.
There’s also an open question around erythritol. A 2023 Nature Medicine study associated higher blood erythritol with cardiovascular events and reported increased platelet reactivity in experimental work. That doesn’t establish that eating these bars causes cardiovascular harm. It leaves a question worth following, rather than a verdict on the ingredient. Perfect Keto and Munk Pack’s selected labels contain no erythritol.
What to avoid for this shortlist
- IQBAR’s lower review-site counts. The Peanut Butter Chip brand label and Chocolate Mint Chip label show 17g carbs, 9g fiber and 0g sugar alcohols: 8g net. Some reviews list 2g or 3g. Use the current package, not recycled numbers.
- Atkins’ glycerin deduction. The Chocolate Peanut Butter label has 23g carbs and 12g fiber. Its 8g sugar alcohol line is glycerin, making 11g net under this guide’s rule, rather than the brand’s 3g.
- Maltitol bars. ONE Maple Glazed Doughnut’s wrapper lists maltitol and maltitol syrup. Barebells Speculoos Cookie Butter does too, with a laxative-effect warning. Both miss the ingredient rule here. A review of sugar alcohols describes differing glucose and insulin responses to maltitol and erythritol. They aren’t interchangeable deductions.
