Best Low Calorie Soy-Free Plant Protein Bars

Promix Nutrition’s Chocolate (Plant) bar leans light and crispy: pea-protein puffs plus added pea protein deliver 10 grams of plant protein, while cocoa powder, dairy-free chips, and a chocolatey drizzle supply the dessert notes.

Carbs sit mid-range and come mostly from refined binders like tapioca syrup and cane sugar, buffered by some soluble tapioca fiber and a touch of chickpea for a steadier ride than straight sugar.

Fat stays modest at 5 grams from confectionery fats such as coconut oil and palm kernel oil in the drizzle, along with cocoa butter in the chips.

The label is vegan and gluten-free with no artificial sweeteners, and it relies on just three common helpers—glycerin for softness, sunflower lecithin to keep the chocolate smooth, and agar for structure.

Mosh’s Pumpkin Spice Chocolate Chip keeps things light and plant-forward: pea protein and almonds anchor the bar, spices and cocoa bring the fall flavor, and the brand’s Brain Blend adds 100% DV vitamin B12 and 25% DV vitamin D3.

Sweetness leans on allulose—a low-calorie sugar that tastes like sugar but barely nudges blood glucose—with tiny boosts from stevia and monk fruit.

Carbs are padded by soluble tapioca fiber, a resistant dextrin refined from cassava that adds bulk and a softer chew, rather than grains; fats come mostly from almonds with a little cocoa butter and coconut oil.

There are four functional additives to keep sweetness, softness, and mixability in line, and the whole thing lands at a very snackable 150 calories.

MOSH’s Chocolate Chip Cookie builds its 11g of protein from pea protein and almonds, then layers in cocoa, cocoa butter (sometimes coconut oil), maple, sea salt, and natural flavors for a cookie‑chip bite.

It’s a light 160‑calorie bar with moderate fat from nuts and cocoa butter and carbs that lean on soluble tapioca fiber (a refined, non‑digestible fiber from cassava) and allulose (a low‑calorie sugar) rather than cane sugar.

In practice, that means sweetness without the syrupy crash; a tiny lift from stevia and monk fruit keeps it tasting like dessert, while small amounts of rice/tapioca starch help the bar hold together.

You also get the brand’s Brain Blend—vitamin D3 plus other nootropic add‑ins—though the amounts aren’t disclosed. The recipe reads mostly whole‑food ingredients supported by four functional helpers for texture and sweetness (a softener, an emulsifier, a refined fiber, and a low‑calorie sugar).

IQBAR Chocolate Sea Salt may sound like dessert, but it’s built like a purposeful plant-based snack. Protein comes from peas—both isolate and tiny crisps—while the chocolate character is real cocoa, unsweetened chocolate, and cocoa butter, finished with a pinch of sea salt.

The macro story is unusual for a chocolate bar: fat-forward, very low in digestible carbs, and modest in calories, with sweetness supplied by stevia instead of sugar. Almonds add creaminess plus a notable amount of naturally occurring vitamin E, which IQBAR also boosts with an added dose.

There’s even a light sprinkle of lion’s mane; interesting, but better treated as a bonus than a benefit.

Vegan bars that aim for keto are uncommon, and this one leans into the classic peanut-butter-and-chocolate lane with real peanut butter, peanut flour and extract, plus dark chocolate chips. Its 11g of protein comes from a plant blend—pea protein isolate tucked into cocoa crisps with brown rice protein—and a small boost from the peanut ingredients.

To keep sweetness in check, it uses soluble tapioca fiber and allulose instead of cane sugar, landing at 1g of sugar with a gentler blood-sugar impact for most people. Fats (11g) come mostly from peanuts and almonds, with cocoa butter lending that chocolate-chip snap and a modest iron bump from the cocoa and plant proteins.

A short list of refined helpers—glycerin for softness and sunflower lecithin for smooth mixing—keeps texture pleasant without piling on additives.

Stars + Honey’s Birthday Cake Chocolate Chip builds its 13 grams of protein on collagen, backed by pea protein, in a gluten‑free, dairy‑free package.

To channel birthday‑cake sweetness without a big sugar hit, it leans on allulose and monk fruit—low‑calorie sweeteners that taste like sugar but have a smaller glycemic impact—plus a bit of plant‑derived glycerin to keep the bar soft.

Most carbs come from fibers refined from cassava (tapioca), oats, and acacia, which add bulk and help with steadier energy. Fats come from almonds, cocoa butter, and a touch of coconut oil, giving the chips structure and the bar a satisfying bite.

There are four modern additives here (sweeteners, a moisture‑keeper, and an emulsifier), while the sprinkles are colored with plants like spirulina, radish, and turmeric.

Atlas leans into peanut butter and dark chocolate but rewrites the sugar script. The protein is fully plant‑based—a rice‑and‑almond base with crunchy pea‑protein crisps—boosted by peanut butter and peanut flour.

The chew comes from soluble tapioca fiber (a refined binder from cassava) and a little plant‑derived glycerin to keep things soft, while sweetness relies on allulose, a low‑calorie sugar that behaves like the real thing, plus concentrated monk fruit extract.

Fats are mostly peanut‑driven, with small amounts of cocoa butter and coconut oil for structure. Net result: a vegan, gluten‑free, keto‑friendly bar with 15 grams of protein, 180 calories, only 0.

5 grams of sugar, and a quietly impressive 38% Daily Value of iron from the cocoa components.

Love Good Fats’ Chewy Nutty White Chocolatey Strawberry leans dessert-first: dry-roasted almonds and cashews underneath, a white-chocolate-style coating with real freeze-dried strawberry on top. Protein comes from milk protein isolate plus crunchy fava-bean crisps, totaling a snack-size 8g, while carbs favor added fibers over sugar.

At 190 calories with 13g of fat and just 2g of sugar, it’s built for keto-style, fat-forward energy rather than a bulk-protein hit.

To pull off the creamy coat and low-sugar sweetness, the recipe uses roughly eight functional add-ons within a longer, about two-dozen-ingredient list—think refined fibers (to add bulk and gentle sweetness), glycerin (to hold moisture), and an emulsifier so the coating sets smoothly.

Built on a pea-and-brown-rice blend, this plant-based bar chases classic brownie flavor with real cocoa plus a touch of vanilla and salt. The macro picture is assertive: 20g protein, 25g carbs, 7g fat, 210 calories, and only 1g sugar.

To hit that low sugar, it relies on soluble corn fiber (a refined fiber made from corn starch), erythritol (a low-calorie sugar alcohol), stevia and monk fruit (high-intensity sweeteners), and a little glycerin (a plant-based syrup) to keep the texture soft.

You will also spot sunflower lecithin in the chocolate for smoothness; altogether seven modern helpers that trade whole-food simplicity for low sugar and a dense, nougaty bite.
