What are the M&M's Hi Protein Bars?
The M&M's Hi Protein Bars are Mars' first-ever protein bar range under the iconic M&M's brand — a range of three flavours (Chocolate, Crispy and Peanut) that each deliver 15g of protein per 51g bar, with real Mini M&M's pieces incorporated inside each bar.
The concept addresses a core demand in the protein bar market: snacks that genuinely taste like confectionery. The M&M's Hi Protein bars achieve this by using the actual brand's chocolate pieces — real Mini M&M's (7% of the bar in the Chocolate variant) — embedded in a milk chocolate-coated, caramel-layered protein matrix. The colourful sugar-coated chocolate pieces are identical to those in standard M&M's packaging, creating a genuinely distinctive visual and textural experience.
Three flavours are stocked. Chocolate delivers the classic M&M's milk chocolate experience — milk chocolate coating, caramel layer, Mini M&M's embedded in the protein base. Crispy adds crunchy M&M's pieces (crispy rice inside sugar-coated chocolate) for a satisfying textural crunch alongside the smooth protein and caramel layers. Peanut incorporates real peanuts (10%) and Mini M&M's for the highest-calorie and most satiating of the three — 209 kcal per bar vs 192 kcal for Chocolate and Crispy.
Available individually or in a box of 12. Not suitable for vegetarians (contains collagen hydrolysate).
The iconic colour, crunch and taste of M&M's. Now with 15g of protein.

🟡 Real Mini M&M's in every bar — genuine brand inclusion, not flavouring
The M&M's Hi Protein bars contain actual Mini M&M's — the same sugar-coated milk chocolate pieces present in standard M&M's packaging — as a declared ingredient (7% in Chocolate). This is a genuine brand inclusion, not an M&M's-flavoured protein bar. The colourful appearance, the candy shell crunch and the chocolate inside are authentic to the M&M's product.
💪 15g of protein per bar — 3x more than standard M&M's
A serving of standard M&M's contains approximately 4 to 5g of protein. Each M&M's Hi Protein bar provides 15g — from a protein blend of milk protein, whey protein concentrate and soy protein isolate — in a single 51g bar.
🍫 Milk chocolate coating with genuine caramel layer
All three flavours are built on a milk chocolate outer coating (16%) and a real caramel layer (10%) — made from sweetened condensed skimmed milk, glucose syrup, invert sugar syrup and butter — that replicates the caramel experience of classic confectionery bars.
🍪 Crispy variant: crunchy M&M's pieces for a distinctive texture
The Crispy variant uses crispy M&M's pieces — which incorporate a rice crisp interior inside the sugar-coated chocolate shell — adding a satisfying crunch throughout the bar that sets it apart from the Chocolate and Peanut variants.
🥜 Peanut variant: real peanuts (10%) for extra satiating fats and protein
The Peanut variant adds real peanuts (10%) to the formula alongside the Mini M&M's, increasing fat and caloric content (209 kcal) while adding natural peanut flavour and the satiating fat-protein combination of classic Peanut M&M's.

Q1 — Are the M&M's pieces inside the bars real M&M's?
Yes. The Mini M&M's included in all three Hi Protein bar variants are the genuine M&M's confectionery product — the same sugar-coated milk chocolate pieces produced by Mars for the M&M's brand. They are not M&M's-flavoured protein pieces or imitations. The colourful appearance, the thin candy shell, the crunch when bitten and the milk chocolate inside are all authentic.
Q2 — What is the difference between the Chocolate, Crispy and Peanut variants?
All three share the same milk chocolate coating, protein blend and caramel layer base. Chocolate contains plain Mini M&M's (7%) embedded in the protein base. Crispy contains crispy M&M's pieces — with a crunchy rice interior inside the sugar-coated chocolate shell — adding a satisfying crunch texture. Peanut adds real peanuts (10%) in addition to Mini M&M's, increasing fat, calories and delivering the natural peanut flavour profile of Peanut M&M's.
Q3 — Why do the M&M's Hi Protein bars have 15g of protein vs 18 to 20g in other Mars Hi Protein products?
The M&M's Hi Protein bars prioritise the confectionery eating experience — the real Mini M&M's inclusions take up volume and ingredient weight that the Bounty and Snickers bars allocate entirely to protein matrix. The trade-off is 15g of protein in exchange for a more genuinely confectionery-like product with the distinctive M&M's colour and crunch.
Q4 — Is the Crispy variant gluten-free?
No. The Crispy M&M's Hi Protein bar contains wheat-derived ingredients in the crispy component (rice flour, wholemeal wheat flour and malted wheat flour), making it unsuitable for individuals with coeliac disease or gluten intolerance. The Chocolate and Peanut variants may also contain traces of gluten from the manufacturing facility.
Q5 — Is the box of 12 more economical than individual bars?
Yes. The box of 12 provides a lower cost per bar than purchasing individually. At one bar per day, the box provides 12 days of supply.
