Best Low Carb Nut-Free Vegetarian Protein Bars

MOSH Peanut Butter Chocolate Crunch leans into the classic pairing of real peanuts and unsweetened chocolate, but its engine is a dairy trio: whey isolate, whey concentrate, and grass-fed milk protein isolate.

To keep sugar low without a chalky texture, it uses soluble tapioca fiber (a refined fiber from cassava) for body, a little agave and vegetable glycerin for moisture, and stevia and monk fruit (concentrated plant sweeteners) with erythritol (a zero-calorie sugar alcohol) for sweetness.

Most of the calories come from peanuts and cocoa butter rather than added seed oils, which lends richness without feeling heavy. A small 'Brain Blend' adds citicoline, lion’s mane, and ashwagandha, plus vitamin D3 for a 15% daily value bump.

Altogether it’s 21 ingredients, with about five modern bar 'helpers' keeping the texture soft and the sugar in check.

Huel’s Dark Chocolate Raspberry wraps a dark cocoa coating around a tart raspberry layer, then keeps sugar low by leaning on maltitol (a sugar alcohol) and a pinch of stevia (a plant-based high-intensity sweetener) instead of added sugar.

The protein is fully plant-based—pea, rice, and wheat gluten—while carbs come mostly from soluble corn fiber (refined from corn starch), with a little glycerol (a plant-derived humectant) to keep the bite soft.

Fats are plant-derived too, mainly sunflower oil and cocoa butter with a touch of flax. At 180 calories and 1g sugar, it reads like a modern, engineered bar, and that is intentional: roughly 10 additives are used to deliver a soft chew and stable sweetness.

A built-in micronutrient blend boosts vitamins and minerals, but if you avoid gluten or react to sugar alcohols, note the wheat gluten and maltitol.

Fiber One's Peanut Butter Chocolate Protein Bar plays the light-but-satisfying card: 10g protein, 10g carbs, 2. 5g fat, 1g sugar, 90 calories.

The protein base is a soy-first blend supported by whey and casein, with a pinch of collagen; flavor comes from peanut flour, real peanuts, Dutch cocoa, and a little peanut oil.

To hit those macros, it leans on five refined helpers - soluble fibers and low-calorie sweeteners that provide sweetness and chew while keeping sugars low - rather than oats or dates; most people find the energy steadier, though sensitive stomachs can notice sugar alcohols.

Fat stays minimal and mostly structural, coming from palm-derived oils with small contributions from peanuts and canola. Net-net: think tidy peanut-chocolate pick-me-up, not a meal.

David Protein’s Cinnamon Roll bar reads like a protein shake in bar form: milk protein isolate, whey, and egg white do the heavy lifting, with a small dose of collagen for texture.

You’re looking at 28g of protein, 12g carbs, 2g fat, and 0g sugar in 150 calories.

Sweetness and chew come from refined helpers—soluble corn fiber and modern sweeteners like allulose and maltitol, with a touch of sucralose and Ace-K—which keep sugar low while maintaining a soft bite.

Fat stays unusually low because the bar uses EPG, a modified plant fat designed to give body with little absorbable fat. The label isn’t minimalist: 19 ingredients, including roughly five additive-style tools that trade simplicity for performance macros.

BHU Foods’ Peanut Butter Chocolate Chip Cookie Dough bar is a keto‑leaning, fully plant‑based recipe built around organic pea protein and peanuts. It skips added sugar in favor of monk fruit and uses soluble tapioca fiber—a cassava‑derived fiber that gives the doughy chew—to bind everything together.

Calories come mostly from peanuts, cocoa butter, certified‑sustainable red palm oil, and coconut‑based MCTs, for 260 calories with 13g of protein and 1g of sugar.

The label stays short, with two functional helpers (sunflower lecithin for stability, monk fruit for sweetness), and the flavors read like your pantry: roasted peanut, vanilla, dark‑chocolate chips with a quiet lift from baobab.

Mint Chocolate Chip from Love Good Fats plays the candy-bar role - real cocoa, a chocolatey coating, and mini chips - yet keeps sugar low by using erythritol (a low-calorie sugar alcohol), stevia (a plant sweetener), and chicory-root fiber (a prebiotic that adds body).

Protein comes from a hybrid blend: pea protein plus whey protein isolate, with a small hit of brown rice protein in the coating, for broad amino-acid coverage with minimal lactose, but it lands at a snack-like 9 grams.

It's intentionally higher-fat and lower-sugar, built on sunflower-seed butter, palm and coconut oils, and cocoa butter for that creamy snap at 190 calories. Expect roughly five functional add-ins to keep sweetness, softness, and structure in line, typical of keto-style recipes even if this one isn't strict keto.

Pulsin’s Caramel Choc Peanut gets its flavor from actual peanuts and dark chocolate, with the caramel note coming from brown rice malt and agave. Protein is a pea‑and‑rice blend supported by the peanuts, so it’s fully plant‑based and gluten‑free.

Macros skew fat‑forward thanks to peanuts and cocoa butter, while total carbs are relatively modest for a bar, with some sugars from those caramel‑style syrups and a touch of grape juice concentrate.

The chips lean on xylitol (a sugar alcohol) to keep the chocolate tasting rich without piling on sugar.

It’s a short label with 0 flagged additives on our count—more nuts, plant protein, and chocolate than lab‑speak—plus familiar helpers like sunflower lecithin and vitamin E to keep texture and fats stable.

Keto Bars’ Chocolate Peanut Butter sticks to the headline: real peanut butter and chocolate, with coconut for chew and richness. It’s a plant-protein bar because the protein comes from peanuts, so the texture is soft and nutty rather than shake-in-a-wrapper chewy.

The ingredient list is short—peanut butter, chocolate, coconut, water, and salt—with two sweeteners (erythritol, a sugar alcohol, and a pinch of stevia) standing in for sugar. Fats from peanuts, coconut, and the cocoa butter in chocolate do most of the fueling, which is why a small bar feels surprisingly satisfying without a syrupy crash.

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.
