Best Highest Fat Protein Bars

FITCRUNCH Chocolate Brownie leans dessert: deep cocoa, chocolate chips, and a chocolate coating wrapped around 30 grams of protein. The protein is a whey‑first blend (isolate and concentrate) supported by soy isolate and a touch of caseinate, putting it near the top for sheer protein per bar.

Texture and richness come from palm oils and cocoa butter, while the carbs lean on refined syrups and starches plus sugar alcohols (low‑calorie sweeteners that some stomachs notice) to keep sugars modest.

You’re also looking at a long, confectionery‑style label—40 ingredients and 14 additives—to engineer that soft‑center, candy‑bar bite. At 410 calories, it’s hefty: more mini‑meal than snack.

Perfect Snacks’ Coconut Peanut Butter bar reads like a pantry, not a lab: peanut butter and coconut lead the flavor, honey holds it together, and the protein comes from milk and egg with a small assist from rice protein.

It’s intentionally rich—22g fat and 350 calories—so it behaves like a mini meal, with 16g protein and a higher‑than‑average carb load mostly from honey and a light dusting of fruit powders.

There are no sugar alcohols, artificial sweeteners, gums, or emulsifiers here—zero additives by our count—just recognizable foods plus a sprinkle of organic greens and seed oils for extra vitamins and minerals.

If you prefer familiar ingredients over engineered sweeteners, this bar stays firmly on the “real food” side of the fence.

This one leans into real chocolate and fruit: cocoa liquor brings deep, dark richness while actual strawberries add a tart‑sweet pop. It’s a keto‑first recipe that prioritizes fats from coconut oil, coconut, almonds, and cocoa butter for slow, steady energy.

Sweetness comes from erythritol—a fermentation‑derived sugar alcohol that provides sweetness with little impact on blood sugar—plus a tiny touch of stevia; there’s no cane sugar. Protein is plant‑based and modest at 5g, so think nut‑and‑cocoa snack rather than protein shake.

The ingredient list is short and purposeful, with minimal additives aimed at preserving that chocolate‑berry profile while keeping sugars low.

Built around pumpkin and sunflower seeds, this vegan, gluten-free bar leans on dark chocolate chips and vanilla for its Chocolate Chip Blondie character. The macro balance is distinctive: 21g of fat leads, carbs stay modest, and protein lands at 12g.

The recipe is short—11 ingredients total—with just one additive (sunflower lecithin to keep the chocolate smooth). Sweetness comes from maple syrup, brown rice syrup (a rice-based sweetener), and the sugar in the chocolate—no sugar alcohols or artificial sweeteners.

Exo’s Banana Bread (Classic) is built like something you’d actually make at home—bananas, sunflower seeds, flaxseed, warm spice, and vanilla—with cricket powder quietly boosting the protein. The macros lean toward fuel rather than a pure protein hit: at 290 calories, fats from seeds and fruit‑forward carbs outpace the 10g of protein.

There’s just one functional additive here, sunflower lecithin, to keep the texture cohesive; chicory root fiber (a soluble prebiotic from chicory) adds body without resorting to syrupy sweeteners. Flavor stays cozy and familiar—ripe banana and banana chips—while the cricket flour brings complete protein and a small bump of iron, not any “buggy” taste.

Perfect Keto’s Chocolate Chip Cookie Dough bar is fat-forward and collagen-powered, with almond butter, cocoa butter, vanilla, and flecks of unsweetened chocolate chips delivering the cookie-dough feel. Its protein comes mostly from bovine collagen peptides—great for skin and joint support, less focused on muscle.

Carbs come from refined fibers—soluble tapioca fiber (a resistant dextrin made from cassava) and acacia from the MCT oil powder—which are generally low-glycemic but can be fermentable for sensitive stomachs. Sweetness comes from monk fruit and stevia, so sugar stays very low without relying on sugar alcohols.

Net effect: classic keto energy and a shorter ingredient list than many bars, just not a protein heavyweight.

KIND’s Almond Butter Dark Chocolate Protein Bar leans on roasted nuts and real dark chocolate for flavor, with soy protein isolate doing most of the protein work and small assists from almonds, peanuts, and a touch of nonfat milk powder.

Despite the “Protein Bar” label, it sits on the lighter side at 12g, while fat leads at 17g—so it’s more filling and clocks in at 230 calories. Carbs are split: prebiotic chicory root fiber helps steady things, and the sweetness comes from honey, table sugar, and a little glucose syrup (a simple liquid sugar).

There’s just one true additive here—soy lecithin, an emulsifier—to help the chocolate set cleanly and stay snappy.

BHU Foods’ Double Dark Chocolate Cookie Dough bar is plant‑based and keto‑leaning: organic pea protein for structure, deep cocoa and no‑sugar‑added chips for flavor, and monk fruit for sweetness.

It reads more like a low‑sugar snack than a protein heavyweight at 8 grams of protein, while fats from cashews, cacao butter, coconut‑derived MCTs, and certified‑sustainable red palm oil do the heavy lifting on fullness.

Carbs stay modest and come largely from soluble tapioca fiber—a cassava‑derived fiber syrup that binds the bar and helps blunt sugar spikes compared with table sugar. The ingredient list skews organic and keeps additives to two, leaning on a touch of lecithin for texture and monk fruit for sweetness.

The result is a soft, fudgey bite that tastes like dessert, not diet food.

Rise Bar Almond Honey keeps the label disarmingly simple: almonds, honey, and whey protein isolate. The whey isolate (a filtered milk protein) drives a sturdy 18g of complete protein, while almonds bring most of the fat and their own mild nuttiness.

Honey binds the bar and supplies familiar sweetness, so the carbs skew quick rather than slow.

With zero additives—no gums, emulsifiers, or sugar alcohols—the flavor reads like real almonds and honey, not a flavor lab, though that clean approach does come with higher sugar and calories than engineered low-sugar bars.
