Mars Snacking's RXBar brand is releasing High Protein Chocolate Chip Peanut Butter, a new flavor addition to the brand’s High Protein roster that offers 19 g of protein and six simple ingredients. The launch comes as consumers increasingly seek out high-protein snacking options made with recognizable ingredients, a shift driven in part by younger consumers prioritizing both nutritional value and transparency around what’s inside, RXBar says.¹

This latest flavor in the RXBar High Protein product line continues to grow the brand’s presence in the high-protein space. While many options in the category lean heavily on complex formulations or artificial additives, RXBar remains focused on providing protein with ingredient transparency at its core, it adds.

“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,” says Leslie Serro, VP of marketing for RXBar, a part of Mars Snacking. “With RXBar High Protein, we’ve shown that you can have it all—without having to compromise.

Made with peanut butter, chocolate, agave nectar, and pea protein, RXBar High Protein Chocolate Chip Peanut Butter is designed to support consumers' days with 19g of plant-based protein, the brand notes.

Each bar reportedly features a soft, chewy texture with confectionary notes of vanilla and rich chocolate, complemented by roasted peanut butter and visible chocolate chunks throughout. According to the brand, a subtle sweetness from agave rounds out the profile, tying everything together in one indulgent bite.

RXBar High Protein Chocolate Chip Peanut Butter joins existing flavors Strawberry Peanut Butter and Vanilla Peanut Butter.

The new flavor will be released at select retailers in June.
