Best Sugar-Free Frosting (2026): 6 Brands Ranked by Net Carbs and Price

Sugar-free frosting ranges from just-add-water mixes with 0g net carbs to supermarket tubs loaded with maltitol and sorbitol. We compared six brands on their nutrition labels and ingredient lists, not on how they taste. That way you can pick the one that matches your carb count and your tolerance for sugar alcohols.

Key takeaways

• Keystone Pantry and Keto and Co list 0g and 0.5g net carbs per serving. That's because they're sweetened with allulose or an erythritol blend instead of sugar.
• Good Dee's Cream Cheese Frosting Mix and Keystone Pantry's mix are the only two here with zero grams of sugar alcohol per serving. Both use allulose, a rare sugar, not a polyol (the chemical family sugar alcohols belong to).
• Pillsbury's Zero Sugar Creamy Supreme is the cheapest option, at about $0.18 per ounce. But its label lists four sugar alcohols: maltitol syrup, sorbitol, isomalt and polydextrose. It also has 4g net carbs per 2 tablespoons, the highest of the six.
• FitBake's jars are the only ready-to-eat frostings in this roundup. Everything else is a mix you prepare with water, butter or cream cheese.
• Three of the six contain erythritol: Keto and Co, FitBake Vanilla and FitBake Chocolate. Makers and food scientists note that erythritol can leave a cooling feeling in the mouth. In frosting that chills and sets again, like frosting left in the fridge, it can also turn gritty as it forms crystals again.
• None of the six list wheat as an ingredient. But FitBake and Good Dee's are made in facilities that also process tree nuts and peanuts. Check that if you're baking for a nut allergy.

How we ranked these

We ranked every product on what's printed on the label or listed on the maker's product page, not on taste. Here's what we looked at:

Net carbs and sugar alcohol grams per serving, from the nutrition facts panel. First-five ingredients, to see what's actually sweetening and thickening the product. Certifications the brand states, such as kosher, non-GMO or gluten-free. Format: ready-to-eat, or a mix you finish with water, butter or cream cheese. Price per ounce, worked out from a store listing we read this month.

We have not tasted or baked with any of these products. So nothing below is a texture or flavor verdict. Where we mention taste or texture, we say plainly whether it's the maker's claim or a guess based on how the sweetener is known to behave.

Keto and Co Buttercream Frosting Mix: the cheapest per ounce, but you supply the fat

Keto and Co's mix is mostly its Wondrose sweetener blend. That blend is erythritol, non-GMO soluble corn fiber, inulin, monk fruit and natural flavors. You heat it with water, then whip in your own butter or cream cheese and vanilla. Albertsons lists it at $4.79 for the 8.1 oz (18-serving) bag. That works out to about $0.59 per ounce, the lowest of any product here. Per serving, the label lists 12.8g total carbs, 5.8g fiber and 6.3g erythritol. That leaves 0.5g net carbs. Erythritol is the main sweetener. So you'd expect the same cooling aftertaste seen in most erythritol-based bakes. You'd also expect the same crystals forming when chilled. Our guide to sugar alcohols in baking explains why.

Keystone Pantry Sugar-Free Butter Cream Frosting Mix: zero sugar alcohols, just add water

Keystone Pantry's mix lists only five ingredients: allulose, cream cheese powder, butter powder, vanilla and salt. It needs nothing but water to become frosting. The single-bag listing we found was Lang's Chocolates, at $7.99 for 7.9 oz. That's about $1.01 per ounce. Amazon sells it as a 6-pack. The brand's own claim is zero net carbs per serving. Allulose is a rare simple sugar, not a sugar alcohol. So its chemistry doesn't predict the cooling effect erythritol produces. That's a guess based on chemistry, not a taste test. The product is certified kosher dairy.

Good Dee's Cream Cheese Frosting Mix: the only mix here with a full nutrition label we could verify

Good Dee's lists a complete nutrition panel. Two tablespoons (19g) prepared gives 60 calories, 11g total carbs and 1g net carbs. The ingredients are allulose, cream cheese powder and butter powder. There's no maltitol and no sugar alcohol at all, since allulose isn't one. Walmart lists it at $13.99 for the 8.2 oz box. That comes to about $1.71 per ounce. So it's one of the pricier mixes, despite the simple formula. It's made in a facility that also processes tree nuts, pecans and peanuts. Nuts aren't an ingredient. Even so, it's not a fit for a strict nut-free kitchen.

FitBake Vanilla and Chocolate Buttercream Frosting: the only ready-to-eat jars

Both FitBake flavors skip the mixing step. You open the jar and frost. The vanilla and chocolate versions share a base of palm fruit oil and an erythritol-monk-fruit sweetener blend. The chocolate version adds cocoa powder. The brand's own facts panel lists 90 calories and 4g total carbs per serving for each. FitBake nets that out to 0g using its own net-carb math. The brand's site charges $13.95 for an 8 oz jar (vanilla) and a 9 oz jar (chocolate). That's about $1.74 and $1.55 per ounce, the highest prices in this roundup. That fits with paying for convenience instead of a mix. The sweetener is erythritol-based. So crystals can form if the jar goes into the fridge and back out. That comes from how erythritol behaves, not from any claim FitBake makes. Both are made in a facility that also processes tree nuts and peanuts.

Pillsbury Zero Sugar Creamy Supreme Vanilla: the cheapest, and the one with the most sugar alcohols

Pillsbury's tub lists maltitol syrup as its first ingredient. Next come palm oil, polydextrose, water, maltodextrin, sorbitol, isomalt and canola oil. Sucralose and artificial colors (Yellow 5, Red 40) sit further down the list. A 2-tablespoon serving has 100 calories, 17g total carbs and 4g net carbs. That's more net carbs per serving than any other product in this table. Walmart lists it at $2.72 for the 15 oz tub, or about $0.18 per ounce. It's by far the cheapest. It's also the only frosting here you can buy at nearly any grocery store. Maltitol, sorbitol, isomalt and polydextrose are all sugar alcohols. Food-science research on sugar alcohols keeps finding the same thing. In larger amounts, they can upset some people's stomachs. Our sugar alcohols explainer covers why in more depth.

Who should buy each type, and who should skip it

Buy a mix (Keto and Co, Keystone Pantry, Good Dee's) if you want the lowest net carbs and don't mind five minutes at the stove or with a mixer. Keystone Pantry and Good Dee's need only water. Keto and Co needs your own butter and vanilla, which is why it's cheaper per ounce.

Buy a FitBake jar if you want to frost a cake in one step and price per ounce isn't your main concern.

Buy Pillsbury if you're avoiding added sugar but not counting net carbs strictly. It suits you if you want something from a regular supermarket and aren't sensitive to sugar alcohols.

Skip Pillsbury if you're following strict keto net-carb limits or have a sensitive gut. Four different sugar alcohols in one tub add up fast. That's especially true if the cake underneath is also sweetened with sugar alcohols.

Skip any of the erythritol-based options (Keto and Co, both FitBake flavors) if you've noticed a cooling aftertaste from erythritol before. Reach for Keystone Pantry or Good Dee's instead, since both use allulose rather than a sugar alcohol.

Want to understand the sweeteners before buying anything? Our guide to choosing sugar alternatives and our erythritol vs. stevia comparison break down how each behaves in a bake.

Here's a hypothetical example (no real order). Frosting two dozen cupcakes takes roughly 12 ounces of frosting. At Keto and Co's $0.59 per ounce, that's about $7 in frosting. At a FitBake jar's $1.74 per ounce, the same batch runs closer to $21. That's a $14 difference for the same cupcakes, before you count the butter the mix also needs.

Frequently asked questions

Is sugar-free frosting keto-friendly?

It depends on the product, not just the “sugar-free” label. Keystone Pantry, Good Dee's and both FitBake flavors list 0g net carbs per serving on their own nutrition panels. That fits most keto carb limits. Pillsbury's Zero Sugar tub lists 4g net carbs per 2-tablespoon serving. That's higher, but still far below Pillsbury's regular, full-sugar Creamy Supreme Vanilla Frosting. A 2-tablespoon serving of the regular version has roughly 23g of total (and net) carbs.

Does sugar-free frosting have sugar alcohols?

Some do and some don't. Keystone Pantry and Good Dee's use allulose, a rare sugar rather than a sugar alcohol. So their labels show none. Keto and Co and both FitBake flavors use erythritol. Pillsbury's tub lists four sugar alcohols: maltitol syrup, sorbitol, isomalt and polydextrose.

What is the best sugar substitute for frosting?

Based on label data alone, allulose-sweetened frostings (Keystone Pantry, Good Dee's) have the lowest net carbs with no sugar alcohols. Erythritol blends (Keto and Co, FitBake) come close. But they carry erythritol's known cooling aftertaste and its habit of forming crystals when chilled. For more on how single sweeteners do in baking in general, see our best sugar substitute for baking roundup.

Can I make sugar-free frosting without a mix?

Yes. Swap the powdered sugar in a standard buttercream recipe for a granulated or powdered erythritol or allulose blend. Chemically, that works the same way these mixes do. Our allulose syrup brand comparison and the confectioner's sugar substitution page cover ratios for DIY versions.

Does Pillsbury sugar-free frosting taste different from regular frosting?

We haven't tasted it ourselves, so we can't give a verdict. Pillsbury's own product description markets it as a like-for-like replacement. The sugar alcohols it uses (maltitol, sorbitol, isomalt) are chosen because they're close to sugar in sweetness and bulk. That's what a maker would point to when it claims the swap works.
