Mint Super Cookie Crunch
TL:DR
In 2 Sentences
A rare mint-chocolate protein bar that actually eats like a meal: 30 grams of protein, a crispy-chewy cookie crunch, and a fortified, engineered build meant to satisfy—not just tide you over.
When to choose MET-Rx Mint Super Cookie Crunch
Best for long days, heavy training windows, or travel when you want a satisfying, mint-chocolate meal replacement with serious protein and calories. A smart pick for athletes or busy folks who prefer one substantial bar over piecing together snacks.
What's in the MET-Rx bar?
Meet MET‑Rx Mint Super Cookie Crunch: a mint‑chocolate, cookie‑crisp bar that behaves more like a portable meal than a dainty snack.
It packs 30 grams of protein from a multi‑source blend—soy crisps, milk protein isolate, whey, and a little egg white—then delivers the flavor with alkalized cocoa, chocolate, and minty natural flavors while the cocoa‑soy crisps supply the cookie‑like crunch.
The flip side is that carbs, sugars, and calories sit toward the top of the category, driven by syrups and starches plus a mix of plant and dairy fats for that candy‑bar melt.
It’s best suited to times when you want big protein and classic mint‑chocolate taste and are comfortable with a sweeter, more processed build.

Protein
3015HIGHThirty grams of protein puts this bar near the top of the category. Most of that comes from a blend: soy protein isolate in the cocoa‑soy crisps, milk protein isolate, whey isolate/concentrate, and a bit of egg white. Together they deliver a complete amino acid profile with fast‑digesting dairy proteins, while also flagging milk/soy/egg allergens.
Fat
109MIDAbout 10g of fat come from canola oil (mostly unsaturated), fractionated palm kernel/palm oils and cocoa butter (more saturated), a touch of dairy butterfat, and some almond butter. The almond and canola bring heart‑friendlier unsaturated fats, but palm and dairy fats push the saturated‑fat share higher than in nut‑centric bars. Expect a pleasant chocolate‑style melt from cocoa butter with a moderately saturated overall mix.
Carbs
4720HIGHThe 47g of carbs are driven mainly by added sugars and syrups (corn syrup, sugar, fructose) plus tapioca starch in the crisp. That mix leans quick‑burn and higher‑glycemic, giving a fast lift rather than slow, sustained energy; oligofructose (a chicory‑root fiber) and the bar’s protein/fat temper the spike only modestly. If you want steadier energy, this isn’t the “slow carb” style.
Sugar
244HIGHThe 24g of sugar come primarily from refined sources—corn syrup, table sugar, and fructose—with a small assist from dairy and chocolate. That translates to pronounced sweetness and a faster blood‑glucose rise; glycerin (a moisture‑holding syrup) and oligofructose add bulk and mild sweetness but are still highly processed sweeteners. If you monitor added sugars, this lands on the higher side for a protein bar.
Calories
390210HIGHAt 390 calories, this sits at the high end for bars. Most of the energy comes from carbs (~47g ≈ 188 kcal), with sizable contributions from protein (30 grams ≈ 120 kcal) and fat (~10g ≈ 90 kcal)—more like a compact meal than a light snack. Useful when you need calories and protein together; heavy if you don’t.
Vitamins & Minerals
The label shows unusually high B‑vitamin numbers (for example, 200% DV biotin and 50% DV B12) alongside vitamin E and several minerals, which is typical of fortified meal‑replacement bars. Dairy proteins and nonfat milk contribute calcium and phosphorus, cocoa brings iron and copper, and almond butter adds some vitamin E; the elevated B‑vitamins likely reflect added fortification.
Additives
Expect a fully engineered texture: glycerin keeps the bar soft, soy lecithin helps oils and water mingle, xanthan gum stabilizes, alkalized cocoa smooths flavor, and tocopherols protect freshness. All are commonly used and safe at food‑use levels, but they signal a highly processed bar rather than a short, pantry‑style ingredient list.

Range
“I buy the Met-RX Big 100 bars because they’re 30-32 grams of protein and they’re quite tasty.”
“I actually buy their cookies n cream bars pretty often. Like the taste, high protein and live an active lifestyle (commute on bike + workout often) so the calories are pretty good for my needs.”
“My favorite of all time it the Met-Rx super cookie crunch bar. 100g Bar for 410 calories, 32g protein, 42g carbs, 14g fat. It’s high in sugar but once in a while it’s my sweet meal. They taste SO good and take me a long time to eat”
Main Praise
Fans love that this bar doesn’t play small. It’s legitimately filling, tastes like mint-chocolate dessert, and delivers enough protein to matter—no “snack in disguise” here.
Reviewers who bike commute, lift, or work long shifts call it clutch: it eats slowly, feels substantial, and keeps you out of vending machines. The texture—crisp bits inside a chewy base—gets frequent compliments, and across thousands of ratings the line stays reliably high.
Even when people rank other flavors first, they often keep Super Cookie Crunch in the rotation for that cooling mint hit and easy meal-replacement utility.
Main Criticism
The sugar lands on the higher side for a protein bar, and some palates find the sweetness—and overall “engineered” flavor—too much for daily use. A few buyers report bars that feel very firm (watch those front teeth), while occasional quality-control gripes pop up across the line.
If you’re aiming for slow, steady energy or prioritize short, whole-food ingredient lists, this build won’t scratch that itch. And while many adore the mint-chocolate profile, others think it leans artificial compared with bakery-style flavors.
The Middle Ground
So who’s right—the folks calling it their favorite, or the ones warning you off cookie crunch altogether? In a way, both.
This bar is designed like a compact meal: big protein, notable calories, classic candy-bar texture, and yes, a sweeter profile. Men’s Health highlights it as a best high-calorie pick; Eat This, Not That likes the taste but flags added sugars; that’s exactly what the label telegraphs.
For a post-workout commute, long ride, or a slammed day with no lunch break, it’s a purposeful tool. For a light, slow-carb snack, it’s the wrong tool.
As for the occasional “too hard” complaints, letting the bar warm up a bit (jacket pocket, quick microwave nudge) usually softens the chew—a small tweak that can make a big difference.
What's the bottom line?
MET-Rx Big 100 Mint Super Cookie Crunch is a mint-chocolate crowd-pleaser built like a portable meal. You’re getting 30 grams of protein, substantial calories, and a crispy-chewy texture that feels indulgent yet practical. The tradeoff is a sweeter, more processed formula with sugars and syrups that bring quick energy rather than slow burn.
If your day calls for a satisfying, one-and-done bar—after lifting, between classes, on the road—this fits the brief. If you’re chasing slow carbs, minimalist ingredients, or a low-sugar routine, it’s not your lane. Note the allergens (milk, soy, egg, peanuts, almonds) and that it’s vegetarian and gluten-free by ingredients.
Condensed listicle blurb: A mint-chocolate meal-in-a-wrapper. With 30 grams of protein and about 390 calories, MET-Rx Big 100 Mint Super Cookie Crunch fills you up fast and tastes like dessert. Great for post-workout or long days; less ideal if you prefer lower sugar or a short, whole-food ingredient list.
