Blueberry Cobbler
TL:DR
In 2 Sentences
A true meal-sized bar: about 400 calories and 30g of protein with a dessert-like flavor and a vitamins-and-minerals boost—rare in a mainstream bar.
When to choose MET-Rx Blueberry Cobbler
Best for active days, long commutes, or post-workout recovery when you want a substantial, sweet-leaning meal on the go without mixing a shake.
What's in the MET-Rx bar?
MET-Rx Protein Bar, Blueberry Cobbler, is a meal-sized bar that marries a bakery vibe with gym-level macros.
The “cobbler” comes from an apple–blueberry fruit paste (for the filling), a touch of malic acid for tartness, and a pastry-ish base that includes enriched wheat flour and a little butter and yogurt powder for that baked note.
Under the hood you get a big 30 grams of protein from a blend of soy crisps, whey, milk proteins, and egg whites, while the carbs lean heavily on fruit paste plus added sugars and starch syrups.
Fats come from palm kernel/palm oil, canola, and a bit of dairy. It’s indulgent in flavor and, at 400 calories, closer to a grab-and-go meal than a light snack.

Protein
3015HIGHMost of the 30 grams of protein come from a blend: soy protein crisps (soy isolate formed into crunchy pieces), whey protein isolate, milk protein isolate and casein, with egg whites in the mix too. That means you’re getting complete proteins from both dairy and egg, plus soy’s solid amino acid profile—fast-digesting whey for a quick bump and slower casein for staying power. It’s not vegan, and while the isolates are highly refined (lower lactose than milk), dairy and soy allergens are very much present.
Fat
109MIDThe 10 grams of fat are a mix of saturated and unsaturated sources: fractionated palm kernel/palm oil and a little butter on one side, canola oil and peanut flour on the other. Palm kernel and butter skew more saturated (firmer texture, good shelf stability), while canola adds heart-friendlier monounsaturated fat. Net-net: moderate fat overall, with a meaningful saturated component typical of coated or pastry-inspired bars.
Carbs
4820HIGHCarbs here are driven by an apple–blueberry paste and several refined sweeteners—corn syrup, glucose syrup, sugar, and some brown sugar—plus refined wheat flour and starches for structure. That’s more “fast fuel” than slow-burn whole-food carbs; expect quick energy with some buffering from the bar’s protein and fat. A bit of added fiber (polydextrose) and glycerin help texture and moisture, but the dominant carbs are still rapidly available.
Sugar
244HIGHYou get 24 grams of sugar, coming from both fruit (apple and blueberry purées/juice) and refined sweeteners like sugar, corn syrup, glucose syrup, and brown sugar. There’s also a sugar alcohol (maltitol) and glycerin for sweetness and softness—useful functionally, but they’re highly processed and can bother sensitive stomachs at higher intakes. In short, sweetness is built from a mix of fruit and refined sources, with a distinctly sweet finish.
Calories
400210HIGHAt 400 calories (near the top of the bar category), this eats like a small meal. Rough math says about 120 calories from protein, ~190 from carbohydrates, and ~90 from fat—so carbs carry the largest share. If you’re replacing a meal or fueling a long workout window, the density makes sense; as a casual snack, it’s substantial.
Vitamins & Minerals
Fortification does the heavy lifting: the added vitamins-and-minerals blend provides about 50% DV of vitamin A and 20% DV of vitamin C, plus iron (~21% DV) and calcium (~12% DV). Some calcium also comes naturally from the dairy proteins and yogurt powder. Don’t expect the blueberry to supply those numbers—the label’s micronutrients are largely from the premix.
Additives
This bar uses a full tool kit of modern additives to hold its shape and taste fresh: glycerin for moisture, a sugar alcohol (maltitol) for bulked sweetness, lecithins and xanthan gum for texture, polydextrose for fiber, and natural flavors and fruit/vegetable juices for color. They’re effective and safe at typical levels, but they are highly refined. If you’re sensitive to polyols or prefer minimally processed ingredients, that’s worth noting.

Range
“I buy the Met-RX Big 100 bars because they’re 30-32 grams of protein and they’re quite tasty.”
“I actually buy their cookies n cream bars pretty often. Like the taste, high protein and live an active lifestyle (commute on bike + workout often) so the calories are pretty good for my needs.”
“My favorite of all time it the Met-Rx super cookie crunch bar. 100g Bar for 410 calories, 32g protein, 42g carbs, 14g fat. It’s high in sugar but once in a while it’s my sweet meal. They taste SO good and take me a long time to eat”
Main Praise
Fans come back for the combo of size, taste, and macros: 30g of protein in a bar that actually fills you up.
Amazon reviewers routinely call out flavors like Salted Caramel Brownie Crunch and the apple variations as standouts, with several noting that it keeps them full and steers them away from drive-thru temptations.
On Reddit, users like CalypsoBrat and CriticalLootRNG praise the high protein and the fact that it’s substantial enough for active days. Texture gets love when fresh: a crispy-chewy interior with a candy-bar finish that doesn’t scream protein powder.
Media roundups echo this—Men’s Health dubbed Big 100 a top high-calorie pick and LIVESTRONG flagged it as a smart meal-replacement for athletes and weight gain. If your goal is convenient calories plus protein, this bar makes that easy.
Main Criticism
Critics point to sweetness first.
With about 24 grams of sugar in this Blueberry Cobbler profile (a mix of fruit sugars and refined syrups), some find it too candy-like for daily use, and a few report a slight chemical or chalky edge in certain flavors.
Texturally, bars can run firm—one Amazon buyer warned to be careful with your front teeth—so temperature and freshness matter. There are scattered quality-control complaints, from odd hard chunks to occasional underweight bars, which is frustrating when you’re buying by the box.
A few flavors skew “kids-cereal sweet” (one buyer even noted tongue tinting), which won’t thrill purists.
And while the protein blend is robust, the ingredient list is long and includes common allergens (wheat, dairy, soy, and peanut via peanut flour), which rules it out for some eaters.
The Middle Ground
A Redditor with the delicate handle im_a_dick_head called out the “shit ton of sugar,” and he isn’t wrong about the sweetness; this is not a minimalist, date-and-nuts bar.
But context matters: at roughly 400 calories with 30g of protein, Big 100 is designed to replace a small meal or refuel real training, not to be a dainty 150-calorie desk snack.
Used that way, the faster carbs, protein blend, and moderate fat can be a feature, not a flaw. Still, if you’re watching added sugar closely, the apple–blueberry filling plus syrups can blow your budget in one go—Eat This, Not That!
made a similar point while still praising flavor and texture. Taste seems flavor-dependent and batch-dependent: GranolaBarHero found it neither great nor terrible, while others swear certain flavors are “so good” they slow you down to savor them.
My read: pick the flavor profile you’re most likely to love, store at room temp (cold makes it harder), and treat it like a compact meal, not a nibble.
What's the bottom line?
MET-Rx Big 100 Blueberry Cobbler is a deliberate choice: a dessert-forward, fortified bar that eats like lunch and drops 30g of protein without a blender. It shines for commuters, students, and athletes who need portable calories and don’t mind a sweeter profile. If you prefer short ingredient lists, lower added sugar, or you’re sensitive to sugar alcohols and long-keep coatings, this won’t be your forever bar.
For everyone else, it’s a reliable grab-and-go meal that tastes like a treat, keeps you full, and lands where convenience meets gym-level macros. Listicle takeaway: 400 calories, 30g protein, bakery vibes—excellent for active days; too sweet for sugar hawks.
