A new twist on breadmaking hits stores next fall as Pillsbury launches its Funfetti Sourdough Bread Mix. The product drops for pre-order on September 24, weeks after Taylor Swift shared her rainbow bread adventures on the podcast New Heights. Each box packs sourdough mix with a splash of color from Funfetti bits, as stated in Pillsbury promotional material sent to PEOPLE. She shared plans for her future nieces: "There's blueberry lemon, there's cinnamon swirl, cinnamon raisin, and this one I've been workshopping for the girls because they love everything rainbow — Funfetti sourdough," Swift told the podcast. Bread has taken center stage in Swift's kitchen.
