Myprotein
Chocolate Peanut Butter
TL:DR
In 2 Sentences
A dessert-leaning, layered bar with a crisp-meets-creamy bite, 20g of protein, and only 4g of sugar—achieved with a soy–dairy–egg protein blend and fiber-based sweeteners instead of lots of cane sugar.
When to choose Myprotein Chocolate Peanut Butter
Best for post-workout or 3 p. m.
sweet-tooth moments when you want real protein without a chalky chew. Skip it if you avoid soy/dairy/egg/peanuts or if highly processed sweeteners and fibers tend to upset your stomach.
What's in the Myprotein bar?
Chocolate meets peanut butter in a bar that leans more confection than trail mix—and its nutrition tells the story.
You get 20g of protein (around the 90th percentile) from a big‑tent blend: soy protein isolate leads, with milk proteins (whey and milk concentrates/isolates) and a touch of egg white rounding out the amino acids.
Carbs skew modern—less oats and fruit, more refined fibers and starches—so sugar stays low while sweetness stays high. Fat comes from real peanuts/peanut butter plus a coating built on palm/shea/sunflower oils, lending that indulgent chocolate‑peanut butter snap.
Flavorwise, it’s classic: roasted peanuts and peanut butter, cocoa powder and unsweetened chocolate, with peanut flour boosting the nutty finish.

Protein
2015HIGHThe 20g of protein come from a blended stack: soy protein isolate at the front, backed by milk proteins (milk protein concentrate/isolate and whey) with a little dried egg white. Blending soy with dairy and egg yields a complete, highly digestible profile while keeping lactose relatively low compared with milk powder alone. It’s a strong, multi‑source approach—just note the allergens (milk, soy, egg) and the use of highly refined isolates.
Fat
109MIDAt 10g, fat is moderate and comes from two places: peanuts/peanut butter (mostly heart‑friendly unsaturated fats) and a coating fat blend that includes palm kernel, palm, and shea alongside sunflower and peanut oils. The tropical fats tip the mix toward higher saturated fat for structure and snap, while the nut and sunflower oils bring it back toward unsaturated. Expect creamy texture and good staying power rather than a strictly low‑fat profile.
Carbs
2520HIGHThe 25g of carbs are mostly engineered rather than grain‑based: soluble corn fiber (a refined fiber from corn starch), polydextrose (a synthetic fiber), and IMO (a starch‑derived syrup that behaves partly like fiber) supply bulk and sweetness; glycerin (a plant‑based moisture holder) keeps the bar soft. Rice and tapioca starch add some quickly digested carbohydrate. Net effect: fewer sugar spikes than a sugar‑heavy bar, though fermentable fibers can cause gas for sensitive guts.
Sugar
44MIDOnly 4g of sugar—a small amount from cane sugar and the chocolate—while most sweetness is carried by fiber syrups (such as soluble corn fiber and IMO), polydextrose, glycerin, and a pinch of sucralose (an artificial sweetener). That keeps the sugar line low, though it relies on highly processed sweeteners rather than fruit. IMO can behave partly like digestible carbohydrate depending on formulation, so individual blood‑sugar responses may vary.
Calories
240210HIGHTotal energy lands at 240 calories (upper‑middle among bars), driven by nut/vegetable oils plus a substantial carb base and 20g of protein. You’d expect more, but several carbs here are lower‑calorie fibers (for example, polydextrose ~1 kcal/g and soluble corn fiber ~2 kcal/g), which trims the total. It eats like a dessert‑leaning protein bar without the calorie load of a true candy bar.
Vitamins & Minerals
Micronutrients are modest; the label highlights about 15% Daily Value of iron, likely from cocoa/chocolate and soy ingredients. Calcium carbonate shows up in the recipe, but the panel doesn’t flag a meaningful calcium %DV here. Tocopherols are present to protect fats from going rancid, not to deliver a significant vitamin E dose.
Additives
This is a highly engineered bar: emulsifiers (lecithins) keep oils and chocolate smooth, and hydrocolloids (cellulose gum, carrageenan, agar) manage chew and stability. A suite of refined fibers/syrups—soluble corn fiber, polydextrose, IMO, plus glycerin—replaces much of the sugar while holding moisture. Effective for texture and shelf life, but more processed than whole‑food bars, and some people notice GI rumbling from fermentable fibers.

Range
“Also the layered bar from MyProtein is super delicious. Tastes like cake and not as thick and chewy as lots of other bars. 10/10 recommended.”
“Myprotein bars taste pretty good. If you’re afraid to commit to one type of bar, I recommend you buy the assortments in a box.”
“But free delivery over £20 so 1kg of whey and you get free bars and trust these bars are insane”
Main Praise
Taste and texture are the headliners.
Marie Claire’s testers singled out the layered build as downright fun to eat—more like a rice-crispy-square riff than a dense brick—and Redditor Cute_Curvy called the layered bar “super delicious… not as thick and chewy.
” Several Amazon buyers echo that the crunch keeps it from feeling mushy, and talkSPORT’s review even gives it the rare compliment of “no chalky aftertaste. ” For a protein bar, that’s high praise.
Add in the macro profile—20g of protein at about 240 calories with only 4g of sugar—and you’ve got an easy dessert swap that still moves the protein needle. Variety also works in Myprotein’s favor; as Redditor thewizard579 put it, trying an assortment box is a low-risk way to find a favorite flavor.
Main Criticism
Sweetness can tip too far for some, and a few tasters report a “chemical” aftertaste—likely the sucralose and fiber syrups lingering more than a simple sugar would. Quality control has had outliers: one Redditor flagged a matcha flavor with a fishy smell, and another called out confusing flavor imagery versus ingredients on a different bar.
There’s also an older black eye—Redditor JAAAAAAAAAAP shared Myprotein’s 2020 apology for mite contamination in The Carb Crusher (a different product line).
Finally, the ingredient list is long and modern: refined fibers like soluble corn fiber and polydextrose (a lab-made fiber), IMO syrup (a starch‑derived sweetener that behaves partly like fiber), and glycerin (a plant-based moisture holder) can be effective, but they’re not whole-food.
Those same fibers can cause gas for sensitive guts. And allergen-wise, the soy–milk–egg–peanut combo excludes a lot of people.
The Middle Ground
So which story wins—the dessert you can lift on, or a lab project in a chocolate coat? Probably both.
The macro math is solid: 20g of complete protein from a soy–dairy–egg blend, moderate fats (largely from peanuts), and restrained sugar for a 240‑calorie package. That’s why so many tasters—from Marie Claire to talkSPORT—praise how easy it is to eat.
But the low sugar isn’t magic; it leans on refined fibers and a bit of sucralose, which can read as too sweet or artificial to some, and may rumble the stomach for others.
Redditor ODonthatBooT’s matcha complaint reminds us flavors can vary widely, while Amazon’s “cardboard” reviewer proves no bar is universally loved. The 2020 mite incident is worth remembering as history—not as a verdict on today’s bars—but trust is earned batch by batch.
The practical truth: if you like dessert-style bars and tolerate modern sweeteners well, you’ll likely enjoy this; if you prefer short, whole-food ingredient lists, you won’t.
What's the bottom line?
Myprotein’s layered chocolate–peanut butter bar nails its brief: a candy‑bar experience with 20g of protein and just 4g of sugar. The texture is the hook—crisp and creamy without the dreaded chalk—and the numbers make sense for a post‑workout capper or a late‑afternoon save when you’re eyeballing the office cookies. Just know what you’re buying.
This is a highly engineered recipe that trades cane sugar for refined fibers and a touch of sucralose. That keeps calories and sugar down, but it’s not a minimalist, whole‑food approach, and some stomachs won’t love the fermentable fibers. Allergen coverage is broad (soy, milk, egg, peanuts), and flavor experiences vary by batch and line.
If you’re game for a dessert‑leaning bar with real protein power, start with a mixed box to find your keeper. If you want simple ingredients above all, this isn’t your bar.
