RXBAR, the Chicago-based bar brand owned by Mars, is extending its High Protein line with a Chocolate Chip Peanut Butter variety, packing 19 grams of plant-based protein into a six-ingredient formulation. The product began rolling out to select retailers in June, with broader distribution to follow in subsequent months.
The new SKU sits within RXBAR's dedicated High Protein tier, which the brand has leaned into as consumers — particularly those in the 18-to-34 demographic — prioritise macronutrient density and ingredient transparency when selecting snack bars. The bar's 19-gram protein count places it toward the upper end of the mainstream bar segment, where most offerings deliver between 10 and 20 grams per serving. Mars did not disclose projected sales volumes, distribution targets, or pricing guidance for the launch.
The product arrives as the high-protein snacking category accelerates. Market researchers have consistently flagged protein-forward formats as among the fastest-growing subsegments within the broader $9 billion-plus U.S. snack bar market, driven by the convergence of fitness culture, weight-management trends, and growing consumer skepticism toward artificial additives. RXBAR's emphasis on a short, recognisable ingredient list — a positioning device the brand has maintained since its 2012 founding — is designed to differentiate it from protein bars that rely on proprietary blends or synthetic sweeteners. The brand was acquired by Kellogg in 2017 for $600 million before passing to Mars as part of a broader portfolio realignment. For context on how Mars is reshaping its better-for-you snacking portfolio, analysts have noted RXBAR as a key vehicle for the confectionery giant's push into functional nutrition.
The Chocolate Chip Peanut Butter variety is described as delivering a chewy, cookie dough-like texture with chocolate chunks and a roasted peanut butter flavour profile — a combination that brand executives say marries sensory appeal with functional credentials. The flavour profile mirrors consumer preference data showing peanut butter and chocolate combinations consistently ranking among the top sellers in the bar aisle. Comparable launches in the better-for-you bar space have demonstrated that familiar flavour architecture can materially reduce trial barriers for new SKUs.
"As demand grows for high-protein snacking options made with recognisable ingredients, RXBAR introduces a timeless flavour that brings together function and taste," the company said in its launch statement. Mars did not make an executive available for additional comment ahead of publication. Expanded retail distribution details are expected to be communicated through trade channels in the weeks following the initial June rollout.
