RXBAR, a brand under the Mars snacking umbrella, has introduced its first new fall seasonal flavor in over four years with the launch of the limited-edition RXBAR Nut Butter & Oat Apple Pie, while also bringing back the popular RXBAR Pumpkin Spice 12g Protein Bar for another seasonal run. This strategic move responds directly to the shifting consumer palate, as market data points to apple emerging as one of the fastest-growing flavor trends for the autumn season.
The new RXBAR Nut Butter & Oat Apple Pie variety is an extension of the brand's Nut Butter & Oat platform, which distinguishes itself through a chewy-crispy texture achieved by combining whole grain oats, cashews, egg whites, and wildflower honey. This product delivers 10 grams of protein per serving alongside a good source of fiber. Its flavor profile is crafted to evoke the sensory experience of a classic homemade dessert.
