SNICKERS Protein (Mars)
Peanut Butter
TL:DR
In 2 Sentences
A candy-heritage bar from Mars that leads with whey protein isolate and delivers 20g of complete dairy protein at 250 calories while holding sugar to 4g via refined sweeteners. It aims to give a true chocolate–peanut butter experience with macro discipline.
When to choose SNICKERS Protein (Mars) Peanut Butter
Reach for it when you want a dessert-leaning protein fix after a workout or during the afternoon slump—and you enjoy chocolate–peanut butter flavors. Skip it if you avoid milk, soy, or peanuts, are sensitive to sugar alcohols, or keep vegetarian (it contains gelatin).
What's in the SNICKERS Protein (Mars) bar?
Peanut butter is front and center here—literally. The flavor is built from peanut butter, roasted peanuts, and peanut flour, with a cocoa note in the coating.
Under the hood, this is a whey‑forward protein bar: whey protein isolate leads, with milk protein isolate (including a partially hydrolyzed form) and whey concentrate rounding out 20 grams of complete dairy protein—well above the typical bar.
Carbs are modern and engineered more than grain‑based: a mix of maltitol (a sugar alcohol), glycerin (a moisture‑holding plant‑derived syrup), and chicory‑root fiber (inulin), with just 4 grams of actual sugar.
Fats come from both sides of the spectrum—heart‑healthy unsaturated fats from peanuts and sunflower oil, and more saturated structure‑providing palm ingredients—landing the bar at a satisfying 250 calories.

Protein
2015HIGHWhey protein isolate tops the label, backed by milk protein isolate (including a partially hydrolyzed form for softness) and whey protein concentrate. That mix gives you complete, highly digestible dairy protein with relatively low lactose and a blend of fast‑acting whey plus slower casein from the milk protein. It’s a robust 20 grams—great for muscle repair—though not suitable if you avoid milk proteins.
Fat
129HIGHThe fat story is a blend of peanuts and oils. Peanuts and sunflower oil bring mostly unsaturated fats, while palm kernel oil and palm oil contribute more saturated fat that helps the bar hold its shape and resist melting. Net effect: creamy peanut richness with a higher saturated‑fat tilt than nuts alone would provide.
Carbs
1920MIDMost of the 19 grams of carbs don’t come from grains; they come from maltitol (a sugar alcohol that provides bulk and sweetness), glycerin (a plant‑based humectant that holds moisture), and inulin from chicory (a soluble fiber). This tends to deliver steadier energy than straight sugar, though maltitol still contributes carbs and can bother sensitive stomachs in larger amounts. Only a small slice is actual sugar, so the energy curve feels more slow‑burn than spike‑and‑crash for many people.
Sugar
44MIDSugar is kept to 4 grams because sweetness leans on sugar alcohols (maltitol), glycerin, and a touch of stevia rather than lots of sucrose. That approach reins in blood‑sugar swings for many, though maltitol remains a refined sweetener and can cause gas or laxation if you overdo it. If you prefer sweetness from fruit or honey, this will read more engineered than pantry‑style.
Calories
250210HIGHAt 250 calories, this sits on the heartier side for a protein bar. Roughly speaking, protein supplies about a third of the calories, the 12 grams of fat a bit more than forty percent, and the rest comes from carbs—many of which are from polyols like maltitol and glycerin that add fewer calories than sugar but still add up. Translation: more like a snack‑meal than a tiny tide‑me‑over.
Vitamins & Minerals
Calcium lands at about 15% of daily value, courtesy of the dairy proteins (whey and milk protein isolates naturally carry calcium). Iron and potassium show up in smaller amounts likely from peanuts and cocoa, but nothing else crosses the 10% mark.
Additives
Expect a standard bar toolkit: glycerin keeps it soft, inulin adds fiber and body, and lecithins (soy and sunflower) help oils and proteins blend smoothly. Maltitol supplies bulked sweetness with fewer calories than sugar, and stevia tops off the sweetness. These are functional, highly refined ingredients—generally safe, but sugar alcohols can be a digestive wildcard for some.

“The absolute best are Snickers Hi Protein. They’re from the UK I believe, but they have them on Amazon in the US. They’re just more expensive since they’re imported (4-5$/each), but I highly recommend them. Great treat and macros.”
“Having my first one rn. I like it. It's better than the cliff Builders bars. I found this at a 7-11, which has few "healthy" options for the desperate and depraved like me.”
“Snickers has a protien bar and its pretty legit tho”
Main Praise
Taste, for many, is the headline.
A steady chorus across Amazon and Reddit says this is one of the better “candy-like” protein bars, with several people calling it tasty, satisfying, and a legit treat with 20g of protein.
A few folks even singled it out as better than stalwarts like certain chocolate-heavy bars they’d been eating for years. The peanut butter flavor reads authentic enough to scratch the itch, and the 4g of sugar is a draw for anyone managing swings in energy.
Convenience matters too: some reviewers loved that they could grab one at a gas station or 7‑Eleven, which beats the usual snack options when you’re trying to up your protein on the fly.
Main Criticism
Texture is the sticking point—often literally. Several reviewers describe it as dense, sticky, and tooth-coating, with a few calling it waxy or bland compared with a real Snickers.
Others were disappointed that it doesn’t deliver the full caramel-and-crunch experience the branding implies; it’s a protein bar first, candy second. Price comes up a lot as well, especially in the U.
S. , where it’s often a premium buy.
And because much of the sweetness comes from maltitol (a sugar alcohol), a subset of people report digestive discomfort if they eat more than one or have a sensitive gut.
The Middle Ground
So which is it: dessert in disguise or just another chewy protein block? The truth sits in the middle.
If you go in expecting a one-to-one Snickers swap, you’ll likely side with the Redditors who call it sticky and underwhelming. If you want a candy-adjacent bite with real protein, it’s closer to the Amazon crowd who say it hits the spot.
The macros are solid—20g of whey-led protein at 250 calories is snack-meal territory—and the peanut butter profile feels honest to the name. But the sweetness play relies on refined sweeteners (maltitol, glycerin, a touch of stevia) rather than fruit or honey, which some will taste and some stomachs won’t love.
One pragmatic tip from years of protein-bar testing: bars like this can feel harder straight from a cold car or fridge; at room temp the chew tends to relax, which can nudge the experience from “tacky” toward “fudgy.
”
What's the bottom line?
SNICKERS Protein Hi Protein Bar, Peanut Butter, is a crowd-pleaser for people who want their protein to feel like dessert without a sugar bomb. It’s not a clone of the original candy bar, but it’s closer than most, with 20g of complete whey-and-milk protein and a legitimately peanut-forward taste. At 250 calories, it’s a more substantial snack, the kind that can stand in for a light breakfast or a post-lift treat.
Where it falters is where most engineered bars do: a love-it-or-leave-it chew and sweetness strategy that leans on maltitol. If your gut handles sugar alcohols and you’re okay with a candy-bar aesthetic that’s actually a protein bar in disguise, this is an easy yes. If you prize minimal ingredients, vegetarian status (there’s gelatin), or the exact Snickers experience, you’ll likely prefer another option.
Listicle-friendly takeaway: Candy-adjacent and peanut-buttery, this 20g bar tames a sweet tooth with 4g sugar at 250 calories—great after the gym or as a dessert swap. Best for chocolate–peanut fans who tolerate sugar alcohols; not for vegetarians or those sensitive to maltitol.
