Peanut Butter Chocolate Crunch

In 2 Sentences

When to choose MOSH Peanut Butter Chocolate Crunch
A low‑sugar, dairy‑protein snack between meals or post‑workout when you want something lighter than a 20‑gram protein brick—and you like peanut butter and chocolate.
What's in the MOSH bar?
MOSH Peanut Butter Chocolate Crunch leans into classic flavor with real peanuts and unsweetened chocolate while building its macros around dairy proteins and low-sugar sweetening. The protein comes from a trio of whey protein isolate, whey protein concentrate, and grass‑fed milk protein isolate—think fast‑acting whey plus slower‑digesting casein from the milk protein.
Carbs are kept low by swapping much of the sugar and starch for soluble tapioca fiber, a touch of agave, vegetable glycerin, and zero‑calorie sweeteners (stevia, monk fruit) with erythritol for bulk.
Most of the energy comes from peanuts and cocoa butter, delivering satisfying fats without relying on added seed oils. A small “Brain Blend” adds vitamin D3 (you get 15% DV here) alongside citicoline, lion’s mane, and ashwagandha.
Peanut butter and chocolate do the flavor heavy lifting; fibers, sweeteners, and lecithin handle the texture and sweetness.

Protein
1315MIDThe 13 grams of protein come from a dairy blend: whey protein isolate and concentrate plus grass‑fed milk protein isolate. Whey is highly digestible and low in lactose—great quality for muscle repair—while milk protein isolate brings casein, which digests more slowly for steadier satiety. It’s a moderate protein dose for a bar, and because it’s dairy‑based, it’s not suitable for those with milk allergy (lactose is low but not zero).
Fat
119MIDFat here leans naturally sourced: peanuts contribute mostly monounsaturated fats, while cocoa butter adds a mix of stearic (a saturated fat that’s relatively neutral on LDL) and oleic acid. There are no added seed oils—just minor sunflower lecithin for texture—so you’re getting richness that supports fullness without a heavy dose of omega‑6 cooking oils. Expect staying power from these fats, not a greasy finish.
Carbs
920LOWCarbs are kept low and largely “engineered” for a gentler glycemic impact: soluble tapioca fiber (a resistant dextrin) supplies most of the carbohydrate, with small amounts from tapioca starch, a little agave, and naturally occurring carbs in peanuts and chocolate. This setup favors steadier energy over quick spikes, though it’s fiber from a refined source rather than whole‑food grains or tubers. It’s more of a low‑carb snack than a carb‑fuelled pre‑workout bar.
Sugar
14LOWOnly 1 gram of sugar—sweetness instead comes from a sugar alcohol (erythritol) and high‑intensity sweeteners (stevia and monk fruit), with a touch of agave for balance. That keeps blood sugar impact low, but people sensitive to sugar alcohols may notice GI rumbling if they stack multiple products in a day. Taste skews sweet-without-sugar rather than fruity or syrupy.
Calories
170210LOWAt 170 calories, this bar sits on the lighter side for the category. Most of those calories come from fats in peanuts and cocoa butter, with a meaningful contribution from the dairy proteins; the carb share stays modest thanks to fiber and low‑calorie sweeteners. The result: a satiating snack that doesn’t feel like a meal replacement.
Vitamins & Minerals
You get 15% of your daily vitamin D, supplied by added vitamin D3 in the brand’s “Brain Blend.” There’s also a small bump of calcium from calcium carbonate, plus minor iron and potassium inherent to the recipe, but this isn’t a multivitamin bar. The D3 is the standout micronutrient here.
Additives
A modern bar toolkit shows up: vegetable glycerin to keep it soft, sunflower lecithin for smooth mixing, soluble tapioca fiber to add fiber without grit, and a blend of erythritol, stevia, and monk fruit to deliver sweetness with minimal sugar. The nootropic “Brain Blend” (citicoline, lion’s mane, ashwagandha) and natural flavors are refined extracts rather than whole-food additions. It’s a relatively clean label for texture and sweetness, but still built with several highly processed helpers common to keto‑style bars.

Main Praise
Fans highlight a modern, well‑balanced build: approachable flavors, a chewy‑crunchy texture, and macros that feel thoughtful rather than extreme. Several outlets back that up—SELF named MOSH Best Protein Bar in its 2025 Pantry Awards, and EatingWell and Health both praised the line’s low‑sugar approach and satisfying bite.
On Amazon, happy reviewers call out the portion size (170 calories) as perfect for snacking and appreciate the dairy‑based protein instead of trend‑chasing filler. The Peanut Butter Chocolate Crunch flavor plays it safe in a good way—real peanuts and cocoa provide familiar richness, while the bar stays tidy in a backpack or desk drawer.
For many, it lands exactly where they want a weekday bar to land: convenient, not cloying, and steadying.
Main Criticism
The pushback clusters in three places: taste, protein amount, and price. A slice of reviewers find some flavors dry or a bit artificial‑tasting, and a few note a detectable sweetener finish—common with erythritol, stevia, and monk fruit.
Protein sits at 13 grams, which lifters chasing 20–25 grams per snack will consider light. Reddit threads also bristle at the Brain Blend: doses aren’t disclosed, and some users question the implied benefits; Health magazine flagged the same point.
Add in comments that the bars feel small for the cost, and you have a product that’s polished but not universally convincing.
The Middle Ground
So, is it a candy bar in a lab coat, as Redditor AntoniaFauci joked? Not really.
The macros are far leaner than a candy bar—1 gram of sugar, whey‑forward protein, and fats coming mostly from peanuts and cocoa butter. But it’s also not a brain supplement.
Citicoline (often studied at 250–500 mg/day), lion’s mane (typically 500–3000 mg), and ashwagandha (around 300–600 mg of KSM‑66) show up here without disclosed amounts, so it’s prudent to view the blend as a bonus, not a promise.
On taste, the safer bet is exactly this flavor: peanut butter and chocolate tend to wear low‑sugar sweeteners more gracefully than fruit‑forward recipes that some reviewers called “off. ” If you’re sensitive to sugar alcohols, start with one bar and see how you feel—erythritol can bother some people at higher daily totals.
And if you want 20‑plus grams of protein, Redditor moderatenerd’s aside that it “looked tasty” may matter less than your macro target; you’ll need a heftier bar.
What's the bottom line?
MOSH Peanut Butter Chocolate Crunch is a well‑engineered snack: 13 grams of dairy protein, 170 calories, and a classic flavor profile that feels comforting without the sugar crash. The fats come from peanuts and cocoa butter rather than added seed oils, and you get a small micronutrient nudge (notably 15% DV vitamin D). ” The catches are straightforward.
Taste can be polarizing if you dislike stevia/monk fruit sweetness, the protein is moderate rather than gym‑bro high, and the Brain Blend reads more like thoughtful garnish than guaranteed benefit. ally, this one earns its spot. If you need vegan, peanut‑free, sugar‑alcohol‑free, or 20‑plus grams of protein, you’ll be happier elsewhere.
Condensed listicle blurb: Peanut‑butter‑cup energy without the sugar rush—13 grams of whey‑based protein, 170 calories, and just 1 gram of sugar, plus a small Brain Blend and 15% DV vitamin D. Great for low‑sugar afternoons and post‑workout snacks; skip if you need 20+ grams of protein or avoid sugar alcohols.
