Best Low Calorie Nut-Free Vegan Protein Bars

Promix’s Mexican Hot Chocolate Protein Puff Bar leans on whey isolate and concentrate, plus a little egg white, to deliver 15g of complete protein in an unusually light package: 140 calories with just 3g of fat.

The carbs are quick and modern—tapioca starch (a fast‑digesting starch from cassava) and organic tapioca syrup—tempered by soluble fibers like tapioca fiber and inulin (refined fibers that add body) plus a touch of glycerin, a plant‑derived syrup that holds moisture so sweetness can stay at 4g of sugar.

The flavor reads classic cocoa with a twist: dutched chocolate for smoothness, cinnamon and vanilla for warmth, sea salt, and a whisper of chipotle heat. It uses a short list of four purpose‑driven helpers—think a sunflower‑based emulsifier and a seaweed‑derived gelling fiber—to keep the puffs crisp yet cohesive.

Big picture, it eats like an airy, crunchy snack rather than a dense meal bar, ideal before or after a workout or anytime you want chocolate with a little warmth.

SimplyProtein’s Peanut Butter Chocolate builds flavor from real peanuts and unsweetened chocolate, then holds it together with soy protein crisps—soy protein isolate puffed into crunchy bits.

The label stays tight: seven core ingredients by our count, plus three functional add-ins that lean on chicory-root inulin and acacia (plant fibers) and a touch of plant-derived glycerin (a syrup that keeps the bar soft) to keep sweetness gentle without artificial sweeteners.

Fats come mostly from peanuts, with small amounts of peanut and sunflower oils; carbs come from brown rice crisps and a little cane sugar, with those fibers adding body and mild sweetness.

It’s vegan and gluten-free, and it eats like a light, crisp snack rather than a dense meal replacement.

Think trail snack first, protein bar second: dates and raisins form the base, gluten-free oats add chew, and freeze-dried raspberries bring that tart pop.

Protein comes via crisp soy pieces—light and crunchy instead of dense—while additives stay minimal, with a little tapioca starch to hold the crisps and rice starch plus natural flavorings to keep the berry notes consistent.

Macros lean toward quick energy: higher carbs and sugars, very low fat, and modest protein. The sweetness comes entirely from fruit, including apple, pear, and grape juice concentrates—flavors your tongue reads as fruit, but sugars your body absorbs quickly.

Huel builds a cookie‑dough moment from a fully plant‑based protein blend—wheat gluten for structure and chew, with pea, soy, and rice proteins rounding out the amino acids—under a chocolatey coat with real chips.

At 178 calories with 13g protein and just 2g sugar, it leans on modern food tech for texture and sweetness: soluble corn fiber (a refined fiber that resists digestion), maltitol (a sugar alcohol that tastes like sugar but contributes fewer calories), and a touch of glycerol to keep it soft—no high‑intensity artificial sweeteners.

Fats come mainly from refined sunflower oil and cocoa butter, with a small whole‑food nudge from ground flaxseed, so the fat profile skews mostly unsaturated. The quiet flex is the micronutrient fortification—vitamins D3, K2, C, E, a B‑complex, and minerals—showing up at meaningful daily values.

Love Good Fats’ Chewy Nutty Peanut Chocolatey is a fat-forward, plant-based bar built around roasted peanuts and a chocolatey coating. Protein is modest at 7g, coming from peanut flour and peanuts with a little brown rice protein in the coating—so it stays dairy-free.

Carbs (15g) lean heavily on chicory-root inulin and soluble corn fiber, refined fibers that add bulk and a gentle sweetness while keeping sugar at 1g and the glycemic punch lower than a typical sugar-based bar.

The richness comes from peanuts plus a blend of peanut, coconut, MCT, and palm oils for a creamy, dessert-like bite and longer-lasting satisfaction.

A small set of functional add-ins (about four) support texture and shelf life—glycerin for moisture, sunflower lecithin to keep the chocolate smooth, stevia for sweetness, and tocopherols to help keep the oils fresh.

No Cow’s Peanut Butter Chocolate Chip reads like a dairy‑free candy bar, but its blueprint is unabashedly functional: 20g plant protein, roughly 200 calories, and only 1g sugar. Protein comes from pea and brown rice, with peanut flour and real peanuts steering the flavor alongside dairy‑free chocolate chips.

Most of the carbs aren’t table sugar; they’re from soluble corn fiber (a refined fiber made from corn starch) and glycerin (a plant‑derived syrup that keeps the bar soft), with erythritol plus tiny amounts of stevia and monk fruit doing the sweetening.

Fats stay modest and mainly peanut‑ and cocoa‑butter–based, which helps keep calories in check. To reach those numbers, the recipe leans on about seven refined helpers—common in low‑sugar bars—so it’s more processed than a date‑and‑nut option.

Misfits Brownie Batter leans into plant power: 14g of protein from soy and pea isolates deliver a complete amino profile with no dairy. The chocolate is the real deal—unsweetened chocolate, cocoa powder (some alkalized), and cocoa butter—for that melt‑in‑the‑mouth finish.

To keep sugar low, it swaps cane sugar for a modern mix of sugar alcohols and refined fibers. Across 17 ingredients and four bar‑helper additives, you get a lower‑calorie, 190‑calorie bar that eats more like a fiber‑sweetened brownie bite than a sugar‑spike dessert.

TRUBAR’s PB & Jelly leans into nostalgia with plant protein rather than whey: a pea-and-brown-rice duo delivers 12 grams, all dairy- and soy-free.

Carbs land on the higher side because the base relies on a tapioca fiber and cassava blend, with a touch of organic cane sugar to pull off the “jelly” note—there’s no actual fruit here.

Fats come mostly from peanuts, supported by RSPO-certified palm oil and a bit of MCT to keep the bar soft and melt-in-your-mouth.

The ingredient list is tidy, with two additives—think an emulsifier and natural flavors—to keep texture and flavor consistent, and you pick up about 10% of daily iron from the plant proteins.

Think soft‑baked cookie, not chalky brick: Nature’s Bakery Chocolate Chip Protein Bar leans into whole grains and real chocolate chips. Its protein is a vegan blend—wheat protein isolate first, then pea, fava, and sunflower—so you get plant power with gluten in the mix.

Carbs run higher thanks to whole wheat flour and oats paired with date paste, cane sugar, and a touch of agave, while fat stays modest from canola oil and cocoa butter.

Two simple helpers keep it tender: glycerin (a plant‑derived syrup) for moisture and gum acacia (a tree‑sap fiber) for structure. Translation: 200 calories of quick energy and chocolate‑chip comfort, with 9g of plant protein riding shotgun.
