Peanutty Caramel
TL:DR
In 2 Sentences
Candy‑bar texture and flavor with legit macros: 20.6 grams of protein, 1.8 grams of sugar, and 213 calories—plus a “peanutty” profile achieved without peanuts.
When to choose Oatein Peanutty Caramel
A post‑workout treat or afternoon sweet fix when you want real protein and low sugar in a candy‑bar format, and you’re comfortable with sugar alcohols and gluten.
What's in the Oatein bar?
Oatein’s Peanutty Caramel bar plays a clever double act: big, top‑decile protein from a multi‑source blend, yet low sugar and only modest fat. The protein backbone is mostly dairy—milk protein isolate and whey isolate—supported by soy protein isolate and hydrolyzed wheat protein, which lifts the total to 20.
6 grams but also means it isn’t gluten‑free or vegan.
Carbs are engineered more than rustic: sweetness and structure come from sugar alcohols and refined fibers (think maltitol, tapioca‑derived resistant dextrin, and chicory‑root oligofructose), with a small nudge of oat flour.
That keeps sugars to 1. 8 grams and helps steady energy for many, though sensitive stomachs may prefer a slow introduction.
Fat stays low at 4. 9 grams, largely from cocoa butter and a bit of coconut oil, so the bar leans light rather than rich.
And despite the name, there are no peanuts here—the peanutty caramel profile is built with flavors, a pectin‑set caramel layer, and cocoa components (cocoa mass, cocoa butter, and cocoa powder).

Protein
2115HIGHProtein comes from a blend led by milk protein isolate and whey isolate, with soy protein isolate and hydrolyzed wheat protein rounding things out. Dairy proteins are highly digestible and complete, while soy adds plant protein and wheat improves solubility (but introduces gluten and has a more modest amino‑acid profile). The mix lands a top‑tier 20.6 grams per bar—great for recovery, with the caveat that it’s not milk‑ or gluten‑free.
Fat
59LOWAt 4.9 grams, fat is on the low side and comes mostly from cocoa butter (chocolate‑style firmness and melt) and a touch of coconut oil, plus small amounts from dairy powders. That means more saturated than unsaturated fats here, but not much overall. The result is a lighter, less calorie‑dense bar rather than a nut‑butter‑rich one.
Carbs
2320MIDMost carbs don’t come from fruit or grains; they’re engineered for sweetness and texture. Sugar alcohols (notably maltitol) and refined fibers (tapioca‑derived resistant dextrin and chicory‑root oligofructose) do the heavy lifting, with a little oat flour and some refined starches (like maltodextrin) for structure. Expect lower sugar and steadier energy than a sugar‑sweetened bar, though the refined starch portion is faster‑burning and the prebiotic fibers/sugar alcohols can bother sensitive stomachs.
Sugar
24MIDOnly 1.8 grams of sugar, largely because sweetness comes from sugar alcohols (such as maltitol) plus a tiny boost from an artificial sweetener (sucralose), with glycerin and prebiotic fibers adding body and mild sweetness. That’s far less sugar than a typical chocolate‑caramel bar, but it’s achieved with highly processed sweeteners rather than fruit or honey. If you’re sensitive to sugar alcohols or quick‑fermenting fibers, start with half and see how you feel.
Calories
213210MIDAt 213 calories (about average for bars), most energy is split between the protein blend and the carbohydrate system; fat plays a smaller role. The low‑fat approach keeps total calories in check, while the fiber and sugar‑alcohol matrix trims sugars without making the bar ultra‑dense. Practically, you’re getting a protein‑forward snack rather than a high‑fat treat.
Vitamins & Minerals
There aren’t standout vitamins or minerals called out above 10% Daily Value. Any small contributions likely come from the dairy ingredients (a bit of calcium and riboflavin) and the oats (trace minerals), but this bar is built for macros and texture, not micronutrient fortification.
Additives
This is a highly engineered bar. Emulsifiers (soy/sunflower lecithin) keep the chocolatey layers smooth; humectants (glycerin) lock in softness; pectin and xanthan set the caramel; and modified starches, fibers, and low‑/no‑calorie sweeteners create a candy‑bar bite with low sugar. If you prefer short, minimally processed labels, note the longer list and the reliance on refined sweeteners and texturizers.

“I can recommend Oatein Hype bars. They are heading in the direction of getting more and more laden with maltitol but for now it's acceptable level. They're delicious. Like Mars bars or milky way.”
Main Praise
Taste and texture are the headline acts. Reviewers consistently describe a soft, fudgy chew under a chocolate shell—more Mars bar than health bar—with sweetness that lands in the “not too much” pocket.
One Redditor even said it’s like a Mars or Milky Way, which is rare praise in protein‑bar land. Independent reviewers on abillion echo the theme: rich chocolate vibe, not cloying, and genuinely satisfying for the calories.
The numbers back up the appeal: 20. 6 grams of protein with just 213 calories and minimal sugar, which makes it an easy swap for a candy bar when you want a protein hit.
Trustpilot shout‑outs also flag good taste‑to‑price value, a nice bonus if you’re stocking up.
Main Criticism
The catch is how Oatein achieves that candy‑bar experience.
Sweetness and structure lean heavily on maltitol and refined fibers, which some people tolerate just fine and others absolutely don’t—bloating or urgency can happen, especially if you’re new to sugar alcohols.
It’s also not gluten‑free or vegan: the protein blend includes dairy and wheat (plus soy), which rules it out for several diets. A small but fair quirk: “Peanutty Caramel” without peanuts may feel odd if you’re expecting actual nuts.
And while some praise the flavor, others note it’s straightforward—tasty, yes, but not layered or complex.
The Middle Ground
So where does the truth land between “tastes like a candy bar” and “engineered snack”? Probably right in the middle.
The bar clearly nails the indulgent brief; multiple reviewers—like the Reddit user who compared it to a Mars bar—weren’t imagining things. At the same time, that indulgence is built with a lab‑smart toolkit: sugar alcohols, prebiotic fibers, and setting agents that keep sugar low and texture high.
If your gut is friendly with maltitol, this formula can deliver steady energy and a treat‑like bite without the sugar rush. If your gut is not friendly, even a great‑tasting bar won’t be worth the symphony in your abdomen.
The macros are undeniably strong for recovery and satiety, but ingredient preferences and tolerances will decide whether “Hype” is your daily driver or an occasional dessert‑swap.
What's the bottom line?
Oatein’s Hype High Protein Bar pulls off a convincing candy‑bar impression with very un‑candy macros. 8 grams of sugar, wrapped in a fudgy, chocolatey bite that many reviewers genuinely enjoy. It’s a smart pick when you want a sweet finish after the gym or a midday lift that won’t blow up your sugar budget.
The trade‑offs are clear: it relies on maltitol and refined fibers, and it isn’t gluten‑free or vegan. If you tolerate sugar alcohols and you’re after dessert vibes with real protein, it’s an easy yes.
If you prefer short‑label, minimally processed bars—or your gut says absolutely not to sugar alcohols—keep looking. Quick take: candy‑bar taste, legit protein, very low sugar; great if you handle sugar alcohols, not one for gluten‑free or vegan eaters.
