If the sugar-free chocolate chips you bought last time ended the evening badly, the ingredient list probably told you why, and it told you before you paid. Two of the six bags below put maltitol first. One has no sugar alcohol at all. The rest sit in between, and one of them carries a second sugar alcohol that is easy to miss.
Here is the ranking, by what is actually in the bag, then the reasoning, then the price. Every figure comes from the brand's own page or a retailer listing, opened and linked. If you want the background on why one sugar-free sweetener behaves so differently from another, allulose is not a sugar alcohol is the place to start.
The six, ranked
Per label serving, 14 to 15g on every bag here.
| Rank | Chips | Sweetened with | Sugar alcohol | Fiber | Price per oz |
|---|---|---|---|---|---|
| 1 | ChocZero Dark | Monk fruit, soluble corn fiber | 0g | 7g | $1.00 |
| 2 | Bake Believe Dark | Erythritol, inulin, stevia | 3g | 5g | $0.53 |
| 3 | Lakanto | Erythritol, monk fruit, tapioca fiber | 4g | 3g | $1.82 |
| 4 | Lily's Semi-Sweet | Erythritol, isomalt, chicory and corn fiber, stevia | 4g | 4g | $0.99 to $1.00 |
| 5 | Ghirardelli No Sugar Added Dark | Maltitol | 7g | 1g | $1.12 to $1.31 |
| 6 | Hershey's Zero Sugar | Maltitol | 7g | 1g | not found |
Regular semi-sweet chips, for scale: Nestle Toll House runs $0.46 an ounce with 8g of sugar a tablespoon.
The order is by stomach load first, because that is the failure that costs you a night rather than a batch. At the same load, the type of sugar alcohol decides it, then price.
Why maltitol sits at the bottom
Hershey's Zero Sugar lists maltitol before the chocolate. So does Ghirardelli's No Sugar Added Dark. Each carries 7g of it per 15g serving, which means close to half of every chip by weight is maltitol. (Target's listing for the Ghirardelli prints the serving as 2 tablespoons, but at about 15 servings to an 8 oz bag it works out to 15g.)
Maltitol is used because it is close to sugar in bulk and in sweetness, 75 to 90 percent as sweet by the review cited further down. Your small intestine only absorbs part of it. The rest reaches the colon, where bacteria ferment it and it draws water in, and that combination is the bloating and urgency people associate with sugar-free candy.
The research is more specific than the reputation. In a 1998 controlled study, young adults eating 30g of maltitol in milk chocolate had no more symptoms than with ordinary chocolate; at 40g they got mild rumbling and gas, but no laxative effect. In a 2007 study where young women took maltitol on its own in steps from 10g up to 45g, 29 of 34 had diarrhea somewhere along the way. The two studies differ in dose, in who took part and in whether the maltitol came inside food, so they do not reduce to one safe number. What they agree on is that the effect climbs with the dose.
Which turns the question into arithmetic you can do yourself.
The dose is the whole story
A batch of cookies usually takes about a cup of chips. USDA puts a level cup at 168g, so with a maltitol chip the whole batch carries about 78g of maltitol, or 3.3g per cookie across 24. Two cookies after dinner is under 7g, well short of the 30g that made no measurable difference in the chocolate study.
Eating the chips from the bag is a different number. It takes 64g of the Hershey's or Ghirardelli chips, a bit over four tablespoon servings, to reach 30g of maltitol. Half an 8 oz bag carries about 53g.
So the honest version is not "maltitol chips will wreck you". It is that they are usually fine inside a cookie, and a real risk eaten by the handful from the bag. Lily's prints "great for snacking straight from the bag" on its own back panel. Tolerance also varies widely from one person to the next, and the polyol review cited below found the dose that triggers symptoms sits lower in people with IBS.
Lily's has a second sugar alcohol
The current Lily's semi-sweet list reads: unsweetened chocolate, erythritol, chicory root fiber, soluble corn fiber, isomalt, a palm kernel and palm oil blend, cocoa butter. Its dark chips page carries a "NEW Rich & Creamy Recipe" tag over the same isomalt.
If Lily's is the brand you settled on because it was the stevia one, the current bag is worth reading. Isomalt is a larger sugar alcohol, built like maltitol rather than like the small erythritol molecule, and in the Koutsou study of polyols in milk chocolate, 40g of isomalt produced more symptoms than 40g of maltitol, including mild laxation. The bag lists 4g of sugar alcohols per tablespoon in total and does not split erythritol from isomalt, so we cannot tell you how much of the 4g is which.
It is still a moderate load, and at about $9 for 9 oz at Target it is the cheapest widely stocked option here. It is just not an erythritol-only chip.
Erythritol: easier on the gut, and the cooling
Lakanto and Bake Believe rely on erythritol, 4g and 3g a tablespoon.
Erythritol is the small one of the sugar alcohols. A systematic review of polyols puts its absorption at around 90 percent in the small intestine; it then leaves in urine, so little of it reaches the bacteria that cause trouble. It is not unlimited. Europe's food safety authority set its acceptable daily intake in 2023 at 0.5g per kilogram of body weight, a figure it based on diarrhea in human studies.
Its signature complaint is taste rather than gut: it absorbs heat as it dissolves, which reads as cool or minty. The erythritol explainer covers that, and the heart research, properly.
Bake Believe is also the cheapest per ounce on this list, at $16.92 for a 32 oz bag at Sam's Club. That listing showed the bag out of stock when we checked, so treat the price as a ceiling on what is possible rather than what you will find this week.
ChocZero: no sugar alcohol, a lot of fiber
ChocZero's dark chips are chocolate, soluble corn fiber, sunflower lecithin, monk fruit and vanilla. No sugar alcohol at all. The bulk that sugar would normally provide is fiber, 7g per tablespoon, which is why the panel reads 8g carbohydrate and 0g sugar.
That is the best answer here if sugar alcohols are your problem. It is not a free pass for every gut. Fiber is fermented too, and a 30g handful of these chips is 15g of it. Bake Believe lists inulin second, and the chicory root fiber in Lily's is inulin by another name. A controlled study of chicory inulin found up to 10g a day was well tolerated in healthy adults, with flatulence the most common complaint.
At $19.99 for a 20 oz bag direct, it works out to $1.00 an ounce, the same as Lily's.
None of them are low calorie
Hershey's, Lily's, Lakanto and ChocZero all print "not a low calorie food" on the label, and it is true of all six. Sugar-free chips run 357 to 429 calories per 100g against 500 for regular semi-sweet.
In a batch of 24 cookies made with a cup of chips, switching from regular to sugar-free saves about 4g of sugar per cookie and 5 to 10 calories. The extra cost of that cup, measured against the regular bag, ranges from $0.42 for Bake Believe to $8.10 for Lakanto.
That is the real decision: about $3 a batch for Lily's or ChocZero, in exchange for taking roughly 96g of sugar out of the cookies. If the sugar is the thing you are managing, that is a reasonable trade. If you were hoping the chips would make the cookie light, they will not.
Where allulose fits
There is no allulose-sweetened chip on this list, because we could not find one with a nutrition panel we could open and read. Allulose would be the obvious next step for a chip: it is a rare sugar rather than a sugar alcohol, and most of it is absorbed before it reaches the colon, though at high doses it can cause the same trouble. If one turns up with a real panel, it goes in this table.
Melting any of these is its own problem, since the sweetener does not melt at chocolate temperatures. Sugar-free chocolate melting explains why a chopped bar beats chips in a bowl.
The short version
If your gut is the problem: ChocZero, then Bake Believe or Lakanto. Read the back of a Lily's bag rather than assuming it is erythritol and stevia alone. Keep maltitol chips for baking, where a cookie carries about 3g, rather than for the handful.
If price is the problem: Bake Believe in bulk when you can find it, Lily's when you cannot.
None of this is medical advice. If you have a diagnosed gut condition or IBS, sugar alcohols and fermentable fibers are worth raising with your doctor or dietitian, because the studies above were run on healthy adults and your threshold may be well below theirs.
