What's in the Peanut Butter Chocolate SimplyProtein bar?

SimplyProtein’s Peanut Butter Chocolate builds flavor from real peanuts and unsweetened chocolate, then holds it together with soy protein crisps—soy protein isolate puffed into crunchy bits.

The label stays tight: seven core ingredients by our count, plus three functional add-ins that lean on chicory-root inulin and acacia (plant fibers) and a touch of plant-derived glycerin (a syrup that keeps the bar soft) to keep sweetness gentle without artificial sweeteners.

Fats come mostly from peanuts, with small amounts of peanut and sunflower oils; carbs come from brown rice crisps and a little cane sugar, with those fibers adding body and mild sweetness.

It’s vegan and gluten-free, and it eats like a light, crisp snack rather than a dense meal replacement.

What are people saying?

Main praise: People love the deliberate cereal-like crunch and crowd-pleasing peanut-butter–chocolate flavor, plus 13 grams of plant protein with very little sugar—and no stevia or sucralose.

Main criticism: For some, the crisp reads as dry or chalky with a faint aftertaste, and 13 grams of protein won’t satisfy anyone chasing a 20-plus-gram bar.

Bottom Line

Choose this if you want a lighter, dairy‑free protein snack with an actual crunch and restrained sweetness. Great between meals, with coffee, or after a light workout when you want something tidy and not cloying.

What's in the Choc Orange TREK bar?

TREK Choc Orange plays the classic combo straight: real cocoa, a bright hit of orange oil, and a plant‑based build that feels like dessert. The protein backbone is soy protein isolate, with peanut butter and cashews adding richness and staying power.

Macros land mid‑pack—219 calories with 15. 8g protein, 9.

1g fat, and 15g carbs—while most of the carbs come from fruitier sources (dates, concentrated grape) and a vegan caramel. You won’t find intense artificial sweeteners here; instead, a short list of familiar ingredients plus a few kitchen‑style helpers (like sunflower lecithin and glycerol) keep the layers smooth and soft.

What are people saying?

Main praise: Fans love that it tastes like a real chocolate‑orange candy bar—bright orange oil over proper cocoa—while staying vegan, gluten‑free, and made with familiar ingredients instead of intense sweeteners.

Main criticism: It’s not the leanest protein‑per‑calorie play, the roughly 12g sugar reads sweet for some, chicory‑fiber can rumble sensitive stomachs, and it’s off the table if you avoid soy, peanuts, or tree nuts.

Bottom Line

Best for dairy‑free or sweetener‑averse snackers who want a chocolate‑orange fix that still brings meaningful protein—perfect for afternoon slumps, hikes, or a post‑gym treat when taste matters as much as macros.

What's in the Dark Chocolate Nut KIND bar?

True to its name, this bar is a pile of roasted peanuts and almonds held together and finished with real dark chocolate and a pinch of sea salt. The protein backbone is soy protein isolate, a concentrated, complete plant protein, with a smaller boost from the nuts themselves.

Sweetness and sticking power come from glucose syrup and honey (quick energy), steadied by chicory root fiber and the nut matrix so it doesn’t feel like a candy rush. Cocoa butter and a touch of palm kernel oil give the chocolate its clean snap.

The ingredient list is short and recognizable, with minimal additives (we count one: natural flavor).

What are people saying?

Main praise: Reviewers love that it tastes like actual food—crunchy nuts and true dark chocolate—with zero chalky aftertaste.

Main criticism: The 12g of protein and refined sweetness won’t thrill macro hawks, and chicory root fiber can bother sensitive stomachs.

Bottom Line

Best for an afternoon pick‑me‑up or travel snack when you want crunch and satiety without chasing 20–30 grams of protein; great for gluten‑free vegetarians who eat honey and soy.

What's in the Chocolate CLIF bar?

This bar doesn’t make you choose between flavor and function: it packs 20g of soy‑based protein beneath a real chocolate profile built from unsweetened chocolate and cocoa. The sweet side is not shy—31g of carbs with 17g of sugar—driven by cane syrup and cane sugar (concentrated sugarcane) plus brown rice syrup, which your body absorbs quickly.

Nine grams of fat from palm kernel oil, seed oils, and cocoa butter give a smooth, creamy bite. It’s plant‑based and gluten‑free, and it’s built more like performance fuel than a minimalist whole‑foods bar.

What are people saying?

Main praise: Reviewers consistently rave about the chocolatey, crunchy taste and the staying power of 20g of complete soy protein—plant‑based, gluten‑free, and genuinely satisfying.

Main criticism: The downsides are the higher sugar and calories, a more processed ingredient list (including palm kernel oil), and a texture some find dense in cooler temps.

Bottom Line

Best for post-workout recovery, long hikes, or any day you need a substantial, chocolate-forward refuel. Less ideal if you’re aiming for a lower-sugar, low-carb snack.

What are people saying?

Main praise: Reviewers love the candy‑bar taste and satisfying heft, plus a legit 20g of complete soy protein—with none of the sugar‑alcohol aftertaste.

Main criticism: The 12g of sugar and a dense, sometimes chalky chew turn off folks who want a lighter, less‑sweet daily bar (and soy is a nonstarter for some).

Bottom Line

Best for post‑workout refueling or long afternoons when you want both protein and quick energy in one wrapper—especially if you prefer real sugar over sugar alcohols.
