Oatein
Confetti Cupcake
TL:DR
In 2 Sentences
A dessert-first protein bar with a strawberry layer and confetti finish that still delivers 18g of protein, lands under 200 calories, and keeps sugar around 3 grams thanks to a fiber-and-sugar-alcohol sweetening system.
When to choose Oatein Confetti Cupcake
Sweet-tooth moments after the gym or at 3 p. m.
when you want a candy-bar experience with real protein. Best if you tolerate sugar alcohols and don’t need gluten-free.
What's in the Oatein bar?
Oatein’s Confetti Cupcake leans into a bakery vibe with white‑chocolate (vanilla) notes, a strawberry ribbon, and colorful sugar strands. Under the frosting, the muscle comes from a four‑way blend—milk protein isolate and whey isolate supported by soy protein isolate and hydrolysed wheat protein—delivering a solid 17.
9g.
Carbs skew modern: soluble tapioca fiber and chicory‑root oligofructose for binding, maltitol and a touch of sucralose for sweetness, plus a little oat flour and some refined starches from the sprinkles.
Fat stays modest (cocoa butter and dairy, sparingly), calories land under 200, and the label reads low sugar because most sweetness comes from sugar alcohols rather than table sugar—great for spikes, worth pacing if polyols upset your stomach.

Protein
1815MIDProtein is built from milk protein isolate and whey protein isolate, backed by soy protein isolate and hydrolysed wheat protein. Dairy isolates are very high quality and cleanly filtered; soy isolate adds plant protein, while the wheat component helps texture but also brings gluten. This blend explains the above‑average 17.9g and why the bar is vegetarian but not gluten‑free.
Fat
49LOWFat is low (4.2g) and comes mainly from cocoa butter in the white‑chocolate coating with a little dairy fat from milk powder. That mix leans saturated (cocoa butter is rich in stearic acid) with some monounsaturates, but the total is modest. No added seed oils show up, and the low fat helps keep calories in check.
Carbs
2420MIDMost carbs are engineered for sweetness and texture rather than coming from sugar. Soluble tapioca fiber (a resistant dextrin from cassava) and oligofructose (a chicory‑root prebiotic) bind the bar and blunt glycemic impact, while maltitol (a sugar alcohol) provides much of the sweetness; there’s also a little oat flour plus refined starch/syrup in the sprinkles and filling. Expect steadier energy than a sugar‑heavy bar, though maltitol isn’t zero‑glycemic and the fibers/polyols can bother sensitive stomachs.
Sugar
34MIDOnly 2.5g sugar shows up because sweetness mostly comes from maltitol and a pinch of sucralose, with minor natural sugars from strawberry puree, sprinkles (sugar/glucose syrup), and milk lactose. That typically means a gentler blood‑sugar rise than a sugar‑sweetened bar, though maltitol still has moderate glycemic effects. If you’re sensitive to sugar alcohols, start with half.
Calories
198210MIDAt 198 calories, energy tilts toward protein and carbohydrate; fat plays a small role. Because many carbs here are sugar alcohols and soluble fibers, they contribute fewer calories per gram than table sugar, helping hold the total under 200. Dessert‑like taste with a lighter calorie footprint than many bars.
Vitamins & Minerals
No vitamins or minerals stand out above 10% DV on the label. You may get a small calcium nudge from the dairy and a little extra from tricalcium citrate in the filling, but this isn’t a micronutrient‑focused bar.
Additives
This is a modern, highly engineered recipe: glycerin keeps it soft, lecithins smooth the coating, pectin and starches stabilize the strawberry layer, and citrate acids manage pH. Color from anthocyanins/caramel gives the confetti look. The sweetening system leans on maltitol plus sucralose—both widely reviewed—but polyols and prebiotic fibers can cause gas or laxation for some.

Range
“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 where the Hype line consistently wins. On abillion, reviewers call out a fudgy, soft chew that’s satisfying without being cloying, and praise the not-too-sweet profile—rare for a dessert-style bar.
A Trustpilot review singles out the Hype bars as “amazing tasting” and a good value, which matters if this is a weekly staple. Over on Reddit, one commenter even likened Oatein Hype bars to Mars or Milky Way, which tracks with the Confetti Cupcake’s creamy coating and candy-bar style center.
Layer that with macros that read like a small meal—18g of protein, modest fat, and sub‑200 calories—and you get a bar that feels indulgent but fits into most training days.
Main Criticism
Most knocks revolve around the sweetening strategy. One Reddit user noted the line is trending more heavily toward maltitol, a sugar alcohol that helps keep sugar low but can bother sensitive stomachs in larger amounts.
The ingredient list is unabashedly engineered—multiple protein isolates, fibers, polyols, and stabilizers—so it won’t satisfy “five-ingredients-only” shoppers. Allergen-wise, the hydrolysed wheat and soy mean this is firmly not gluten-free, and some reviewers suggest flavor complexity can be straightforward: think candy-bar comfort over culinary fireworks.
The Middle Ground
Here’s the trade: a dessert-like experience and friendly macros in exchange for a modern sweetener stack and a long label.
If you’re taste-driven, the odds are good you’ll be happy—people keep praising the Hype bars’ soft chew and balanced sweetness, and one Redditor’s “like a Mars bar” comment is the kind of comparison brands wish they could buy.
If you’re ingredient-minimalist or maltitol-sensitive, that same formula could be the deal-breaker. The Confetti Cupcake flavor doubles down on the treat angle with a white-chocolate-style shell and strawberry ribbon, so the expectations are clear: this is candy-bar-adjacent fuel, not a whole-foods bar.
Glycemically, it should hit gentler than a sugar-bomb, but maltitol isn’t a free pass—pace yourself, especially if your gut is the dramatic friend in the group. The truth sits in the middle: it’s a thoughtfully engineered, very tasty option that favors enjoyment and convenience over simplicity.
What's the bottom line?
If you want a bar that feels like a mini party and still brings 18 grams of protein to the table, Oatein Hype Confetti Cupcake delivers. It’s soft, sweet without going saccharine, and surprisingly satisfying for 198 calories. Reviews consistently back the flavor and texture, and the value proposition is strong if you’re rotating through a box.
The caveats are straightforward: it’s built with maltitol and other modern sweeteners, so sensitive stomachs should start with half. It’s not gluten-free and does contain soy.
If you prefer ultra-short ingredient lists, this won’t be your match; if you want a dessert-leaning protein hit you’ll actually look forward to eating, it very likely will be. Condensed listicle take: A candy-bar-style protein fix—18g protein, under 200 calories, cupcake vibes—best for sweet-tooth gym days if you handle sugar alcohols; not for gluten-free eaters.
