Promix Nutrition
Mexican Hot Chocolate
TL:DR
In 2 Sentences
A light, crispy whey‑based bar that skips high‑intensity sweeteners and adds a gentle cinnamon‑chipotle warmth to classic cocoa. It packs 15g of protein in just 140 calories—more ‘cocoa cereal bar’ than candy.
When to choose Promix Nutrition Mexican Hot Chocolate
Best for pre‑ or post‑workout, or anyone who wants a not‑too‑sweet, gluten‑free, vegetarian‑friendly chocolate snack with a subtle heat. Less ideal if you want marshmallow‑style goo or avoid milk, egg, or coconut.
What's in the Promix Nutrition bar?
Promix’s Mexican Hot Chocolate Protein Puff Bar leans on classic dairy strength—whey protein isolate and concentrate—backed up by a little egg white for structure. That combo delivers complete, fast‑digesting protein in a bar that’s unusually light: just 140 calories with only 3g of fat.
The carbs skew modern rather than old‑school: quick‑energy tapioca starch and organic tapioca syrup are tempered by soluble fibers (tapioca fiber, inulin) and a touch of glycerin to keep sweetness up while sugar stays modest.
If you’re picturing the flavor, it’s built the traditional way—dutched cocoa (for a smoother, less acidic chocolate), cinnamon, vanilla, a pinch of sea salt, and a chipotle whisper for warmth—plus a bit of unsweetened chocolate and coconut oil to round the edges.
Big picture, you get mid‑pack protein, low calories, and a refined‑carb base softened by fiber, which makes this feel more like a crisp, airy snack than a heavy meal bar. It’s tailor‑made for pre‑ or post‑workout, or any time you want chocolate with a little heat without committing to a high‑calorie brick.

Protein
1515MIDMost of the 15g of protein comes from whey protein isolate and concentrate, with egg whites playing a supporting role. Whey—especially the isolate here—is low in lactose, highly digestible, and quick to absorb, which makes this bar a solid around‑workout option. The blend keeps quality high while giving the puffy texture its structure.
Fat
39LOWWith just 3g total, this is a lean bar. The fat that is present comes mainly from organic coconut oil and a little cocoa butter from the unsweetened chocolate—more stable fats and not heavy on omega‑6 seed oils. Low fat keeps calories down, though it also means less built‑in satiety if you’re using it as a stand‑alone meal.
Carbs
1720MIDCarbs here are mostly refined rather than whole‑food: tapioca starch for quick lift and organic tapioca syrup for sweetness, balanced by soluble fibers (tapioca fiber, inulin) and a touch of glycerin to hold moisture. That mix should feel peppier than oat‑ or date‑based bars, with the fibers and protein helping to smooth the rise. Think quick energy, not a slow‑burn hiking ration.
Sugar
44MIDSugar stays modest at 4g, driven mainly by organic tapioca syrup and small contributions from chocolate ingredients. Much of the sweetness and softness comes instead from glycerin (a plant‑derived humectant) and soluble fibers, so you’re not relying on a big sugar hit—or on high‑intensity artificial sweeteners. It tastes chocolatey because of the cocoa and vanilla, not because it’s loaded with sugar.
Calories
140210LOWAt 140 calories, it sits near the low end of the bar world. Most of those calories come from protein and carbs, with very little from fat. The result is a lighter bite that’s easy to slot before a workout or as a mid‑afternoon hold‑over.
Vitamins & Minerals
You get about 10% of daily calcium, primarily from added calcium carbonate, with a small assist from the dairy proteins. Otherwise, there aren’t big vitamin spikes—this is a protein‑and‑energy play more than a multivitamin in disguise.
Additives
A few functional helpers keep the puff light and stable: sunflower lecithin (an emulsifier from sunflower seeds), glycerin (to hold moisture and soften texture), and agar (a seaweed‑derived gelling fiber). The soluble fibers (tapioca fiber, inulin) are refined ingredients used to add body and curb sugar. Overall, it’s a short list of common, purpose‑driven additives rather than a long roster of harsh sweeteners.

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
Fans keep coming back to the texture and the restraint. Multiple reviewers describe it as a grown‑up crispy rice vibe—light, airy, and easy to digest—without the cloying sweetness or the telltale aftertaste of artificial sweeteners.
Several Redditors noted it’s more filling than its calories suggest and praised the “bang for your calories” ratio, especially around workouts.
Food editors at SELF, EatingWell, and Health also singled out the line for that nostalgic crunch, the lack of intense sweeteners, and a flavor profile that reads like cocoa cereal rather than a protein science experiment.
For this Mexican Hot Chocolate flavor specifically, the cinnamon‑chipotle warmth adds character without turning it spicy, which makes the chocolate feel richer than the numbers would suggest.
Main Criticism
Expectations can trip people up.
If you’re picturing a gooey Rice Krispies square, this isn’t it—several buyers called the puffs firmer and the overall bar drier than they expected, with one Amazon customer flat‑out calling it crumbly.
A few tasters picked up a slightly chalky, whey‑ish finish, and others noticed a coconut note from the coconut oil that they didn’t love. Health editors also flagged that inulin (a chicory‑like fiber used here) can bother sensitive stomachs.
And at 140 calories with just 3g of fat, it’s a light snack, not a meal stand‑in—great for the gym, underwhelming if you’re starving.
The Middle Ground
So where does the truth land? Right in the middle of expectation and design.
This bar is purpose‑built to be crisp and light, which is why it eats more like cocoa cereal squares than marshmallow treats. Lower sugar and low fat help keep calories down, but they also trade away some softness and gloss—hence the occasional dryness callout.
One Redditor loved that it “doesn’t taste super sweet,” while another complained the puffs were “larger and harder. ” Both are describing the same thing from different angles.
If you’re after a clean‑tasting chocolate crunch with a gentle cinnamon‑chipotle wink and no stevia/sucralose, you’ll likely be in the happy camp. If you want gooey nostalgia and dessert‑level sweetness, you’ll keep searching.
The smart play: treat it as a pre‑lift snack or pair it with a latte, fruit, or yogurt when you want more softness and staying power.
What's the bottom line?
Promix’s Mexican Hot Chocolate Protein Puff Bar succeeds on its own terms: 15g of quick‑digesting whey in 140 calories, a true crispy texture, and chocolate that tastes like cocoa first—not like flavoring. The cinnamon‑chipotle warmth is subtle and welcome. It’s also gluten‑free and vegetarian, though it does contain milk, egg, and coconut.
The flip side of the lean build is predictable: it can read a little dry, and if inulin bothers your stomach, proceed thoughtfully. If you want a not‑too‑sweet, crunchy chocolate bar for the gym bag or the mid‑afternoon lull, this is an easy yes. If your heart is set on gooey marshmallow, you’ll call it a near miss.
Set expectations to “crunchy cocoa cereal bar with a gentle kick,” and it delivers. Condensed listicle blurb: Crispy, not gooey—15g of whey in 140 calories with cocoa, cinnamon, and a mild chipotle warmth, and no high‑intensity sweeteners.
Great pre‑ or post‑workout; may feel a touch dry if you expect a marshmallow treat. Contains milk, egg, and coconut.
