Rxbar has expanded its high-protein snack range with the launch of high-protein chocolate chip peanut butter, a new plant-based protein bar containing 19g of protein and made with six ingredients.

The new flavour joins the brand's existing high-protein portfolio, which includes strawberry peanut butter and vanilla peanut butter variants.

According to the company, the product is designed to meet rising consumer demand for protein-rich snacks made with recognisable ingredients, particularly among younger consumers seeking both nutritional benefits and greater ingredient transparency.

Made with peanut butter, chocolate, agave nectar and pea protein, the bar delivers 19g of plant-based protein and contains no artificial ingredients.

Leslie Serro, vice president of marketing at Rxbar, part of Mars Snacking, said: “High-protein is no longer a niche need – it’s an everyday expectation. And consumers are looking for products that deliver on taste and simplicity at the same time."

Rxbar said the new flavour combines roasted peanut butter with chocolate chunks and vanilla notes, alongside a soft, chewy texture and sweetness from agave nectar.

The launch forms part of the brand's ongoing strategy to offer high-protein products with simplified ingredient lists, differentiating itself from products that rely on more complex formulations.

The new flavour will begin rolling out at select retailers from June.
