# Fall-Inspired Protein Bar Flavors RXBAR Debuts Nut Butter & Oat Apple Pie and a Spice Protein Bar By Kalin Ned | Published 2026-08-10 | Marketing Source: Trend Hunter, https://www.trendhunter.com/trends/rxbar1 References: [prnewswire](https://www.prnewswire.com/news-releases/rxbar-introduces-its-first-new-fall-seasonal-flavor-in-more-than-four-years-tapping-into-the-growing-apple-pie-flavor-trend-302845825.html)  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](https://www.trendhunter.com/trends/pumpkin-spice-greek-yogurt-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](https://www.trendhunter.com/trends/pip-nut-protein-bars) 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](https://www.trendhunter.com/trends/protein-pie).
