Mint Chocolate
TL:DR
In 2 Sentences
A crunchy, cereal-bar-style protein bar built from whey protein puffs, flavored with real chocolate, mint essential oil, and mint leaves—no high‑intensity sweeteners—at just 150 calories.
When to choose Promix Nutrition Mint Chocolate
Reach for it when you want a crisp, mint‑chocolate snack with moderate sweetness and 15g of quickly absorbed protein—especially pre/post‑workout or as a light afternoon pick‑me‑up.
What's in the Promix Nutrition bar?
Promix Nutrition’s Mint Chocolate Protein Bar leans on real chocolate and real mint—cocoa powder, unsweetened chocolate, semi‑sweet chips, mint essential oil, and even mint leaves—for the flavor you’re expecting. Under the hood, the protein comes from chocolate whey protein puffs (a blend of whey isolate and concentrate) with a supporting cameo from egg whites in the marshmallow layer.
The macros skew light—150 calories with modest fat—so most of what you’re paying for is protein and quick-to-moderate carbs bound together with a little soluble fiber. If you want bright mint‑chocolate with middle‑of‑the‑pack protein and a lighter calorie footprint, this bar fits that brief.

Protein
1515MIDThe 15g of protein is built on chocolate whey protein puffs—primarily whey isolate (low in lactose) plus whey concentrate—backed by egg whites in the marshmallow. That combo gives you complete, highly digestible dairy-and-egg proteins that absorb relatively quickly, great around activity or as a tidy snack. It sits around the middle of the pack for protein per bar, but the quality of the protein sources is top‑tier.
Fat
49LOWAt 4g, fat is on the lean side and comes mostly from coconut oil and the cocoa butter naturally present in chocolate. These are predominantly saturated fats (coconut more so; cocoa butter skewing toward stearic and oleic acids), but the overall amount here is small. If you rely on fat for staying power, know this bar keeps it modest—more mint‑chocolate snap than slow-burn richness.
Carbs
1720MIDCarbs here are a mix of refined sources—tapioca syrup (from cassava), a bit of cane sugar in the chocolate chips, and tapioca starch in the puffs—tempered by added soluble fibers (tapioca fiber and chicory root inulin) and a touch of glycerin for softness. Expect quicker energy from the syrups and starch, with the fiber helping to steady the ride compared with straight sugar candy. These are not whole‑food carbs like oats or sweet potato; they’re engineered for texture and binding with some fiber layered in.
Sugar
54MIDSugar lands at 5g, primarily from the cane sugar in the semi‑sweet chips and the tapioca syrup in the marshmallow. There are no high‑intensity artificial sweeteners; some sweetness also comes from glycerin (a plant‑derived humectant) and the fibers, which keep labeled sugars lower than the overall sweetness suggests. Think moderate sweetness from refined sources rather than fruit‑based sugars.
Calories
150210LOWAt 150 calories, this bar is notably lighter than most. Most of the calories come from the whey/egg protein and the cassava‑ and cane‑derived carbohydrates; fat contributes the least. It’s a clean, quick snack when you want protein and mint‑chocolate flavor without a heavy calorie load.
Vitamins & Minerals
Two minerals peek above 10% DV: iron (about 14% DV) likely comes from the cocoa and chocolate, and calcium (about 13% DV) is boosted by calcium carbonate in the protein puffs, with a little help from dairy proteins. Nothing here is megadosed—just small wins from the chocolate and a touch of fortification.
Additives
A few functional helpers keep the texture on point: sunflower lecithin for smooth chocolate, agar (a seaweed‑based gelling agent) to set the marshmallow, glycerin for moisture, and soluble fibers (tapioca fiber and inulin) for body and fiber content. These are refined ingredients used at low levels to hold everything together without resorting to artificial sweeteners. Overall, a short list of purpose‑driven additives that are common in bars like this.

Range
“I love these ProMix Protein Puff Bars. They taste kind of like a rice crispy bar. The chocolate chip is great. I also like the coconut, though the chocolate chip are better. I haven’t yet tried the other flavors.”
“I actually really like the promix bars because they don't taste super sweet (and I hate bars with artificial sweetener). I also find them more filling than other bars, probably bc they're not too sweet.”
“The promix are a little more bang for your calories”
Main Praise
Taste testers and reviewers keep coming back to two things: the throwback crispy texture and the clean sweetness without artificial sweeteners. Major outlets like SELF, EatingWell, and Health all flagged the bar as a standout for delivering that rice‑crispy‑adjacent crunch with real chocolate and mint, not stevia or sucralose.
Many folks on Reddit also appreciated that it isn’t cloying; a couple even said the lighter sweetness made it more satisfying. The macros fit neatly into a lean snack window—15g of high‑quality protein in a 150‑calorie package—so it slots well around workouts or between meals.
Add in a small bump of iron and calcium from the chocolate and fortified puffs, and you’ve got a bar that feels purposeful without tasting like a chore.
Main Criticism
Texture is the sticking point for detractors: several Amazon reviewers and a few Redditors described the puffs as denser and drier than a true rice crispy treat, sometimes even a bit chalky.
A handful found the bar crumbly or noted a noticeable coconut note from the coconut oil, which not everyone wants in non‑coconut flavors. Health’s testers also flagged that chicory‑root inulin (a soluble fiber) can bother sensitive stomachs—something to know if you’re in that camp.
Finally, some editors called out price as a drawback, and if you’re expecting marshmallow‑gooey nostalgia, the experience can feel like a bait‑and‑switch. This isn’t a dessert bar; it’s a crisp protein bar with dessert flavors.
The Middle Ground
So which is it—nostalgic treat or dry impersonator? The truth sits squarely in the middle.
If you go in expecting a gooey, buttery square, you’ll likely side with the Amazon reviewer who said “the resemblance ends there.
” But if you want a crispy, airy bar that dodges the bitter aftertaste common with artificial sweeteners, you’ll probably agree with the SELF and EatingWell teams who put it near the top of the heap.
One Redditor praised that it’s “not super sweet,” which is exactly the point: cane sugar and tapioca syrup provide moderate sweetness, while fiber helps temper the rush. The coconut note some people catch?
That’s from coconut oil; if you’re coconut‑averse, mint‑chocolate might still work, but test one bar before buying a case. And for the dryness critique, pairing it with coffee, tea, or a yogurt solves most of the quibbles—hardly scientific, but practical.
What's the bottom line?
Promix’s Mint Chocolate Protein Puff Bar is a crisp, mint‑forward chocolate snack with 15g of high‑quality protein and no artificial sweeteners, all at 150 calories. It’s vegetarian and gluten‑free, but not vegan (whey and egg whites) and contains coconut. The sweetness comes from cane sugar and cassava‑derived syrup, not fruit—so it reads as moderately sweet and clean rather than candy‑like.
If you love crunchy cereal bars and want a light, no‑nonsense protein hit, this is a smart pick for gym bags and desk drawers. If you prefer soft, brownie‑like bars, or your stomach bristles at chicory‑root fiber, you may want to look elsewhere. Manage expectations—think crisp mint‑chocolate protein bar, not gooey marshmallow square—and it delivers exactly what it promises: real mint, real chocolate, and a tidy dose of protein that won’t weigh you down.
