Best High Protein Wheat-Free Vegetarian Protein Bars

David Protein’s Fudge Brownie is built like a macro tool: very high protein and very low calorie. The protein backbone is a dairy-and-egg blend (milk protein isolate, whey protein concentrate, egg white) with a little collagen, which keeps lactose low while delivering a robust amino profile.

The chocolate flavor comes from Dutch-process cocoa and unsweetened chocolate rather than added sugar.

Sweetness and chew are engineered from refined sweeteners and binders instead of fruit or cane sugar, and the bar uses EPG, a modified plant oil that mimics fat with fewer calories, alongside a touch of coconut oil.

Big picture: it’s a highly formulated, lean, chocolatey bar; if you want whole-food carbs and richer fats, plan to pair it with fruit or nuts.

Chocolate leads the flavor, but the build is decidedly protein-first: whey isolate and crunchy whey crisps backed by egg whites, with a supporting dash of bovine collagen. Sweetness and chew come from cassava-derived tapioca syrup and a milk-chocolate coating made with Dutch-processed cocoa, with a little erythritol to keep labeled sugars in check.

Fats stay modest, mostly from the coating’s palm and palm-kernel oils, a touch of canola, and some coconut, so the profile reads classic chocolate rather than nut-butter.

The ingredient list is modern and polished, using glycerin (a plant-based syrup that holds moisture) and soluble corn fiber (refined from corn starch to add bulk) to lock in that soft-crisp bite.

This plant-based S’mores bar leads with numbers: 20g protein from a pea-and-brown rice blend, just 4. 5g fat, and 1g sugar at 190 calories.

The campfire flavor comes from dairy-free chocolate and sugar-free marshmallow pieces sweetened with sugar alcohols and set with carrageenan—a gelling agent made from seaweed. Carbs clock in at 26g, but most of that comes from refined fibers and low-calorie sweeteners rather than table sugar, which for many people means a steadier energy curve.

It’s a modern, engineered recipe with about 11 additives—think soluble corn fiber (refined from corn starch), glycerin (a plant-based syrup for moisture), and a blend of erythritol, stevia, and monk fruit—so if sugar alcohols or prebiotic fibers usually bother your stomach, pace yourself.

Kirkland Signature’s Chocolate Brownie is built like a protein-first bar: a whey-and-milk isolate base for the heavy lifting, real cocoa for the brownie notes, and sweetness handled without much sugar. Most of the carbs come from soluble tapioca fiber—a refined resistant dextrin made from cassava—that gives chew while contributing fewer digestible carbs than syrups or flours.

Erythritol (a sugar alcohol made by fermentation) and stevia (a plant-derived high-intensity sweetener) provide sweetness with a smaller glycemic nudge than cane sugar. Fat stays modest and mostly comes from cashews and cocoa butter.

The trade-off is an ingredient list that’s concise but clearly engineered, which helps keep calories lean for the amount of protein you get.

Quest’s Peppermint Bark leans into dairy proteins—milk protein isolate and whey protein isolate, plus a touch of sodium caseinate—to deliver 21g of complete protein in a compact 180‑calorie bar. The macros skew protein‑forward with modest fat (7g) and very low sugar (1g), with most carbs coming from low‑glycemic sweeteners and fibers rather than oats or dates.

Flavor cues are straightforward: cocoa for the chocolate, natural flavors for the mint. And yes, those red sparkles are real—tinted with radish juice—signaling a bar that embraces modern food science to keep sweetness high and sugar low.

ONE Brands x HERSHEY'S Double Chocolate is built to taste like the real thing—thanks to cocoas (including alkalized cocoa for a deeper, smoother profile), real chocolate, and cocoa butter. Beneath that flavor-first coating sits a dairy-based protein blend that delivers 18 grams per bar.

Carbs run higher and come largely from refined fiber syrups and sugar alcohols—ingredients designed to be sweet and chewy while absorbing more slowly than table sugar—rather than oats or dates. Fat is mid-range and skews saturated because palm oils and cocoa butter are doing the chocolate-texture work.

It’s a 24-ingredient recipe with four functional additives that manage sweetness, softness, and shelf life—very much a modern, engineered bar.

Chocolate peanut butter shows up honestly here—cocoa, cocoa butter, peanut butter, and real peanuts—wrapped around a plant‑protein core. The 20g of protein comes from soy protein isolate and concentrate.

Carbs and sweetness run higher for a protein bar because the recipe uses cane syrup and cane sugar (straightforward sucrose) plus brown rice syrup, which is made by breaking rice starch into simpler sugars for quick energy.

Chicory root fiber contributes soluble, prebiotic fiber, and the fats come from peanuts alongside palm kernel and cocoa butter, a mix that’s creamy but a bit higher in saturated fat. Vegan and gluten‑free, it reads like a performance snack engineered for texture and reliability.

KIND’s Crispy Chocolate Peanut Butter looks like a treat, yet it’s built like a serious snack. Its muscle comes from soy protein isolate—a complete, dairy‑free plant protein—while peanuts drive flavor and add a little extra protein.

Sweetness skips table sugar in favor of allulose (a low‑calorie sugar) plus soluble fibers refined from cassava (tapioca fiber) and chicory (inulin), and fats from peanuts, palm kernel oil, cocoa butter, and peanut oil deliver that crisp bite.

You’re looking at 20 grams of protein, 250 calories, and only 1 gram of sugar, with just two true additives: soy lecithin to keep things blended and mixed tocopherols (vitamin E) to protect the oils.

The trade‑off is that carbs come mostly from engineered fibers—great for steadier energy for many, though some people feel GI rumbling from chicory or larger amounts of allulose.

Think! Brownie Crunch is built for brownie lovers who want protein: 20g per bar from a blend led by soy protein isolate, supported by whey isolate and calcium caseinate.

The sweetness skips cane sugar entirely, leaning instead on maltitol syrup (a sugar alcohol) and vegetable glycerin (a plant-derived syrup) to keep sugar at 0g while preserving a soft, fudgy chew.

Cocoa and a little real chocolate carry the flavor, while 8g of fat come from almond butter plus small amounts of palm kernel and sunflower oils. It’s a fairly processed formula that uses three modern helpers—maltitol, glycerin, and lecithin (an emulsifier)—for texture and sweetness, totaling 230 calories in a gluten-free bar.
