Best Low Calorie Gluten-Free Plant Protein Bars

Peanut Chocolate Chip reads like a classic—roasted peanuts and real chocolate—but the nutrition is deliberately modern. The protein base is a whey‑forward blend of whey and milk protein isolates, while sweetness relies more on low‑calorie sweeteners than cane sugar.

Most of the carbs come from soluble tapioca fiber, a refined fiber from cassava that adds body and helps keep the sugar impact gentler, with erythritol (a sugar alcohol) plus stevia and monk fruit supplying sweetness without many calories.

Fats are primarily from peanuts and cocoa butter rather than added seed oils, and MOSH folds in a small "Brain Blend" featuring vitamin D3 and B12. Net effect: a light, steady‑energy snack, not a meal replacement.

Promix Nutrition’s Pumpkin Spice (Plant) packs its protein into crunchy pea‑protein puffs, then layers on a French‑vanilla drizzle and real cinnamon‑nutmeg‑ginger spice.

Most of the carbs come from tapioca syrup and rice starch—simple, quick energy—tempered by a little soluble tapioca fiber, a refined fiber made from cassava that helps with texture and slows the rush a touch.

Fats stay modest and come from coconut and sustainably sourced palm kernel oils in the drizzle, which create a firm snap and quick melt. You also get a quiet bonus: plant‑based iron from peas and chickpea.

The label is straightforward, with a couple of functional helpers—glycerin (a plant‑derived syrup that keeps it soft) and agar (a seaweed‑based gelling fiber)—and no high‑intensity sweeteners.

Mosh’s Peanut Butter Crunch leans on dairy proteins—whey isolate, whey concentrate, and milk protein isolate—anchored by real peanuts for flavor and texture. It’s a trim 170-calorie bar with just 1 gram of sugar; sweetness comes from stevia and monk fruit rather than syrups.

Carbs are “engineered clean”: a refined, resistant tapioca fiber provides most of the bulk, with a little tapioca starch and plant-derived glycerin to keep the bar soft and cohesive. Fats land in the middle and are mostly peanut, with a touch of cocoa butter for creaminess.

Beyond that, you’ll spot a small Brain Blend and four functional add-ins—fiber to bulk and bind, glycerin to retain moisture, sunflower lecithin to emulsify, and stevia/monk fruit to sweeten—used for texture and stability rather than to goose the macros.

IQBAR’s Almond Butter Chip leans fully plant-based, anchored by pea protein and real almonds, with unsweetened chocolate and cocoa butter bringing the chocolate note. It’s built as a low-carb, higher‑fat snack that draws steady energy from nuts and cocoa fats rather than sugar, and it’s gently sweetened with a touch of stevia.

The ingredient list is short and largely pantry‑familiar, with minimal additives and no sugar alcohols. Bonus: you get a full day’s worth of vitamin E, plus meaningful iron and magnesium from the almond‑cocoa base.

Raw Rev’s Chocolate Chip Cookie Dough goes all‑in on plant ingredients: a pea‑and‑rice protein blend tucked into a cashew base, warm vanilla, and real organic dark chocolate chips. At 180 calories with 11g of protein and 20g of carbs, it leans on a tapioca‑derived prebiotic fiber for structure and mild sweetness instead of straight sugar.

Fat runs a bit higher from nuts, seeds, and a touch of coconut oil, which is why the texture reads doughy rather than chalky. Sweetness stays modest—mostly monk fruit, with a little cane sugar in the chocolate chips—so the effect is dessert‑ish without a sugar rush.

It’s a concise ingredient list with about four functional helpers to keep things soft and the chocolate behaving, all in a dairy‑free, gluten‑free package aimed at steady energy.

good! snacks’ good!

KETO Choc Fudge reads like dessert but builds its base with plant protein. Pea protein crisps team up with brown rice protein, while almond butter, alkalized cocoa, dairy-free chocolate chips, and cocoa butter create that fudge-like chew.

Instead of dates or oats, it leans on soluble tapioca fiber and allulose—a low-calorie sugar—to bind and sweeten with a gentler blood-sugar impact. Fats come primarily from almonds and cocoa, not added seed oils, and the bar stays light at 170 calories with just 1g sugar.

Additives are kept modest: two small helpers, vegetable glycerin for softness and sunflower lecithin for texture.

Stars + Honey’s Dark Chocolate Coconut builds its chocolate the old-fashioned way: cocoa powder, cocoa beans, and cocoa butter, with real coconut and coconut oil for a toasty finish. It’s dairy-free and gluten-free, with 13g of protein from pea protein plus a touch of collagen - helpful for texture but it does make the bar non-vegetarian.

Carbs lean modern rather than grain-based, using soluble tapioca fiber and allulose to deliver sweetness and chew with a gentler blood-sugar impact than cane sugar.

Fats come mostly from almonds and coconut, with a little cocoa butter, landing at 170 calories and 8g of fat, and the cocoa helps nudge iron to about 10% of the Daily Value.

A short trio of functional helpers - sunflower lecithin to help ingredients blend, vegetable glycerin for softness, and rosemary extract to keep the fats fresh - rounds out the label.

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 Dark Chocolatey Sea Salt & Almond leans plant-based and fat-first: fava bean protein crisps with a touch of brown rice protein deliver 8g of protein, while almonds, coconut oil, and some MCTs power most of the calories.

The flavor reads like dessert—dark-style cocoa, sea salt, roasted almonds—with a low-sugar profile sweetened by stevia. Carbs skew lower for the category because much of the sweetness and texture come from added fibers and glycerin, which help tame blood sugar swings.

You’ll also see modern helpers like soluble corn fiber and chicory-root inulin (refined plant fibers), glycerin (a plant-derived humectant), and sunflower lecithin/tocopherols for texture and freshness—effective tools if you prioritize low sugar over minimal processing.
