Magic Spoon
Blueberry Muffin
TL:DR
In 2 Sentences
A crispy, marshmallow-style cereal bar with real blueberry bits and a bakery-inspired flavor, kept low in sugar via an allulose–stevia–monk fruit blend. It stays notably light at 140 calories while still delivering 12g of complete milk protein.
When to choose Magic Spoon Blueberry Muffin
A lower-sugar, gluten-free sweet snack when you want something fun but not heavy—afternoon pick-me-up, pre- or post-workout nibble, or a “dessert with benefits. ” Best for keto-leaning or carb-conscious eaters who tolerate dairy and alternative sweeteners.
What's in the Magic Spoon bar?
Magic Spoon’s Blueberry Muffin bar leans on milk proteins—casein up front, whey concentrate later—to deliver its protein, while the blueberry character comes from freeze‑dried blueberries and natural flavor.
It’s a notably light bar at 140 calories, achieved by swapping much of the sugar and starch you’d expect in a muffin for low‑calorie allulose and soluble fibers (tapioca fiber and inulin).
The fats are a mix: heart‑friendly almond butter meets palm‑derived oils and a touch of cream. Net effect: a keto‑leaning, dessert‑styled bar that tastes like a treat, with most sweetness coming from modern sweeteners rather than sugar.

Protein
1215MIDProtein here comes from a classic dairy duo: casein plus whey protein concentrate. Together they form a complete, highly digestible protein with casein’s slower release and whey’s quicker uptake—good for satiety without the chalky taste. At 12g (around the lower third among bars), it’s a moderate protein boost rather than a heavy hitter, and it does contain milk allergens.
Fat
69LOWThe 6g of fat is modest and comes from almond butter (mostly monounsaturated) alongside palm kernel/palm oil and a little cream, which add more saturated fat and structure. This mix keeps the bar tender and shelf‑stable, though palm‑based fats are less heart‑friendly than nut oils. If you’re watching saturated fat, this bar’s total fat is low, but its sources are mixed.
Carbs
1720MIDCarbs are engineered more than whole‑food: tapioca starch plus refined soluble fibers (tapioca fiber and chicory‑root inulin), with a small lift from freeze‑dried blueberries. Allulose and a bit of glycerin provide sweetness and softness with less blood‑sugar impact than regular sugar. Expect steadier energy than a muffin made with flour and sugar, though sensitive guts may notice the fermentable fibers.
Sugar
14LOWOnly 1g of sugar, mostly from the blueberries and trace dairy sugars; the sweetness instead comes from allulose (a low‑calorie sugar) plus high‑intensity stevia and monk fruit. This keeps glycemic impact lower than a typical sweet bar, but it also means the sweetness is built from refined ingredients rather than fruit or honey. If you’re sensitive to alternative sweeteners, start with one bar and see how you feel.
Calories
140210LOWAt 140 calories (very low for a protein bar), this reads more like a snack than a meal replacement. Calories are spread across protein and a small amount of fat, with allulose and fiber displacing much of the usual sugar/starch load. That sweetener strategy keeps calories down without going completely spartan on texture or taste.
Vitamins & Minerals
You get about 10% of daily calcium, likely from the dairy proteins and cream, with a small nudge of iron (about 6% DV) that can come from nuts. This isn’t a fortified, multivitamin‑style bar; the micronutrients reflect the ingredients rather than added premixes.
Additives
The label includes several functional, refined helpers: sunflower lecithin to keep things smooth; glycerin to hold moisture; and a sweetener system of allulose plus stevia and monk fruit for sweetness without sugar. Soluble tapioca fiber and chicory inulin add fiber and help with texture; they’re well‑tolerated by many but can cause gas or bloating for some at higher intakes.

What are people saying?
Sources
Range
“I’ve only had their protein bars, and I think they’re really good! Like a healthier rice crispies.”
“I really like these. They have a nice crunch and only 1g sugar.”
“Magic spoon bars at Costco. They taste like rice krispie treats”
Main Praise
Start with texture: the bar is crisp and crackly, more “treat” than taffy, which a lot of people find surprisingly fun. Many tasters say it channels a rice-crispy vibe with a blueberry swirl, and several reviewers even call the Blueberry Muffin flavor their favorite.
For the macros, it punches above its weight—12g protein and very little sugar at only 140 calories—so it scratches the sweet itch without feeling like a commitment. The lower-glycemic sweetener system earns points from folks watching blood sugar; one CGM-using reviewer reported minimal spikes.
Nutrition writers have been kind, too: Well+Good said the bars are worth the hype, and Eat This, Not That! crowned the line a best-in-category crispy bar.
Put simply, if you like cereal bars and want something lighter than the typical brick-like protein bar, this one lands.
Main Criticism
Not everyone swoons.
A recurring theme is aftertaste: if stevia or monk fruit reads “bitter” to you, you’ll likely notice it here, and a few people call the flavor bland or a little artificial.
Texture can lean crumbly, and the bar is more snack than meal—12g protein isn’t a heavy hitter if you’re used to 20g-plus. Sensitive stomachs may find the chicory and tapioca fibers gassy, and a tiny minority report odd reactions to sweeteners.
Ingredient purists may also balk at palm-derived oils and the overall reliance on refined sweeteners instead of sugar or dates.
The Middle Ground
Here’s the real divide: if your gold standard is a classic marshmallow-rice square, this gets charmingly close, which is why Reddit threads brim with “tastes like a Rice Krispie treat” comments.
But if you dislike high-intensity sweeteners, you’ll probably side with the skeptics—one Amazon reviewer called the aftertaste “chemical,” and a Redditor declared the brand “the worst,” which sounds more like internet theater than nutrition analysis.
The nutrition sits in the middle ground: complete dairy protein, very low sugar, and low calories, achieved with allulose and fibers rather than flour and syrup. That tradeoff delivers a lighter bar and steadier carbs for many, but it also introduces the possibility of stevia notes and GI grumbles.
Blueberry Muffin specifically skews a touch more aromatic and is a crowd favorite in mixed reviews, but expectations matter: think smart treat, not bakery muffin in bar form. Try one before buying a case, especially if you know you’re sensitive to alternative sweeteners.
What's the bottom line?
Magic Spoon’s Blueberry Muffin bar is a clever, crispy detour from the usual chewy protein bar: 140 calories, 12g protein, and a dessert-like texture that feels playful rather than punishing. It’s gluten-free and keto-leaning, built on milk proteins with sweetness from allulose plus stevia/monk fruit to keep sugar at 1g. You’ll love it if you want a lower-sugar, lower-calorie sweet snack that actually tastes like a treat.
You’ll be lukewarm if you’re hunting for 20g protein or you’re stevia-averse. sweet tooth shows up and you want something fun that won’t derail the rest of your day. Contains milk and almonds.
