Best High Protein Nut-Free Gluten-Free Protein Bars

David Protein’s Peanut Butter Chocolate Chunk is the definition of protein-first: a milk-protein–based bar with 28g per serving and very little fat or sugar on board. The recipe leans on milk protein isolate and whey, plus egg white, with a little collagen for texture.

Flavor comes from defatted peanut flour, peanut extract, and dark cocoa, so you get the profile without a lot of peanut oil. Sweetness is built from modern, low-calorie sweeteners, and a modified plant fat called EPG supplies creaminess with fewer calories than regular oil.

With roughly six functional additives keeping everything soft, sweet, and stable, this is a deliberately engineered bar aimed at clean macros over minimal processing.

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.

Kirkland Signature’s Chocolate Peanut Butter Chunk sticks to a classic dairy duo for protein—milk protein isolate plus whey isolate—then leans on real peanut butter, peanut flour, and Dutch‑processed cocoa to land the chocolate‑chunk flavor.

Carbs come mostly from soluble tapioca fiber, a refined fiber made from cassava, with erythritol and a touch of stevia providing sweetness instead of sugar. Fat stays modest and mostly peanut‑derived, with a little cocoa butter for richness.

The additive list is short and functional—sweeteners plus a pinch of sunflower lecithin to keep everything smooth—yielding 21g of protein, 23g of carbs, 6 grams of fat, and just 2g of sugar in 190 calories.

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.

Pure Protein’s Chocolate Peanut Caramel leans on dairy isolates for the bulk of its 20g of protein, with a small assist from soy isolate and a touch of collagen.

Sweetness sidesteps table sugar in favor of sugar alcohols (low‑calorie sweeteners that taste like sugar but digest differently) plus a pinch of sucralose—processed, yes, but effective for keeping sugar low and calories tight.

Fats come from a mix of palm‑derived and dairy sources, balanced by peanuts and a little almond butter. Flavor cues are familiar: roasted peanut, alkalized cocoa, and buttery caramel.

It’s a 31‑ingredient, additive‑forward build (nine notable sweeteners/texture helpers), engineered more like a modern protein treat than a minimalist 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! Banana Oat Muffin runs on a dairy duo—milk protein isolate and whey protein isolate—for 20g of protein at a lighter 200 calories.

The muffin vibe comes from whole‑grain oats, and the banana note is from natural flavors rather than fruit. Carbs skew higher on the label, but much of that is low‑calorie fiber and sugar alcohols, not table sugar.

Fat is moderate and comes mostly from almond butter and cocoa butter. You’re looking at a modern low‑sugar build with a handful (seven) refined sweeteners and texture aids—useful for keeping energy steadier, though some people feel them in their gut.

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.
