Best Highest Calorie Protein Bars

FITCRUNCH’s Caramel Peanut looks and eats like a candy bar—peanuts, a caramel‑style layer, and a chocolatey shell—but its core is whey and milk protein isolates with a small dose of soy.

Most carbs come from refined sweeteners and softeners rather than grains: sugar alcohols and glycerin that keep sugar modest and texture soft. Fats tilt saturated because of palm and palm‑kernel oils, with some lift from peanut and almond fats and a touch of cream.

You’ll also see roughly 11 functional additives (emulsifiers, stabilizers, color) that make the coating smooth and shelf‑stable. Under the hood it packs 30 grams of protein in a 380‑calorie bar.

MET-Rx Big 100 Vanilla Caramel Churro leans hard into dessert nostalgia while packing serious protein. Its METAMYOSYN protein blend starts with soy protein crisps, then layers in whey and milk protein isolates plus egg white—an animal-and-plant mix that drives a big protein number.

On the flip side, it’s high for carbs, sugar, and calories, so it behaves more like a small meal than a light snack. The churro-caramel profile comes from cinnamon, classic sugars and syrups (corn and brown rice), and creamy touches like yogurt powder, butter, and heavy cream.

You’ll also see a modern bar build: eight functional additives keep it chewy and shelf-stable, and the label is heavily fortified—think protein bar meets multivitamin.

Gatorade’s Mint Chocolate Crunch is a dessert‑style recovery bar: chocolate coating, semisweet chips, minty natural flavor, and cookie‑crisp bits wrapped around 20g of dairy protein. The protein is mostly whey with some milk protein, while the carbs and sugars sit high thanks to classic candy‑style sweeteners, caramel, and chocolate.

Fats come from palm‑based oils plus cocoa and dairy fats that help those layers hold together. Expect a longer, confection‑leaning ingredient list with about nine common stabilizers and emulsifiers to keep everything snappy and shelf‑stable—more “treat with benefits” than minimalist snack.

Perfect Snacks’ Dark Chocolate Almond reads like a pantry bar first and a protein bar second: almond butter and honey lead, with dark chocolate, nonfat dry milk, and a little egg and rice protein holding things together.

The protein lands at 12g from a milk-and-egg–led blend, while fats sit higher at 19g thanks to almonds, cocoa butter, and a small mix of olive and seed oils. Carbs reach 25g, including 17g of sugar from honey and dark chocolate—there are no sugar alcohols or artificial sweeteners.

A sprinkle of fruit and greens powders rounds out the label, and the texture stays soft when you let it warm slightly from the fridge.

Exo’s PB & J (Classic) tastes like a lunchbox staple because it’s built like one: roasted peanuts, a jammy mix of strawberries and apricots, honey, and a touch of vanilla. The twist is the protein—cricket powder—an animal-derived, complete protein that also brings vitamin B12 you rarely see in fruit-and-nut bars.

The ingredient list is short and leans real‑food, with no sugar alcohols or artificial sweeteners; the strawberry component uses apple juice concentrate to boost sweetness and a little citric acid for tartness, much like adding lemon to jam.

Macros skew richer—higher carbs, sugar, fat, and calories—so think trail fuel or a hold‑you‑over snack rather than a feather‑light bite.

Built like a mini meal, Premier Protein’s Dark Chocolate Almond leans on a soy–whey blend with a touch of collagen to deliver 30g of protein. The chocolate‑almond character comes from alkalized cocoa, vanilla, and dry‑roasted almonds.

It’s an ingredient‑dense bar (about 21 items) with four common bar helpers—glycerin to keep it soft, chicory‑root inulin to add fiber and body, soy lecithin to hold it together, and stevia to stretch sweetness without more sugar.

Expect top‑tier protein, carbs on the higher side, moderate fat, and 290 calories, which puts it closer to a small meal than a light snack.

Think classic PB–chocolate, but built to do more than treat your sweet tooth. The protein base is whey protein isolate—complete, comparatively low in lactose—with freshly ground peanut butter doing double duty for flavor and a little extra protein.

It runs richer than the average bar because the fat comes mostly from real peanut butter (plus a touch of coconut oil and cocoa butter), and the carbs come from certified gluten‑free oats and familiar sugars like honey, brown rice syrup, and coconut sugar.

There are no sugar alcohols or intense artificial sweeteners, so the sweetness reads like a pantry, not a lab. If you want something that tastes like dessert yet behaves like a small meal, this is squarely in that lane.

Chocolate mint fans, meet a plant-powered heavy hitter: CLIF’s Chocolate Mint Protein Bar uses soy protein isolate and concentrate to hit 20g of complete protein. For sweetness and structure it leans on cane sugar and brown rice syrup—fast-burning carbs—plus a palm-kernel-oil chocolate coating that stays crisp in a backpack.

It’s vegan and gluten-free, with its mint-chocolate flavor coming from cocoa, unsweetened chocolate, and a touch of natural mint. You also pick up meaningful iron and phosphorus from the soy and cocoa, and a couple of standard bar additives keep the texture stable and the coating smooth.

The tradeoff is higher sugar and carbs than many bars, so think fast fuel plus protein rather than a slow, all-afternoon nibble.

Dark chocolate meets roasted almonds, with puffed brown rice for a chewy‑crisp bite and a sticky swirl of brown rice syrup holding it together. The protein is a plant‑based pairing of organic pea and sprouted brown rice, clocking in at a lighter 10 grams per bar—no whey, no soy.

Where it leans hard is energy: 37 grams of carbs, mostly from brown rice syrup and coconut sugar (including what’s in the dairy‑free chocolate chips). Fat lands at a moderate 10 grams from almond and sunflower seed butters plus a touch of cocoa butter, which rounds the sweetness and keeps it satisfying.

The ingredient list reads like a pantry—organic nuts, seeds, cocoa, rice—with no artificial sweeteners, sugar alcohols, or preservatives.
