Chewy, cozy, and full of old‑fashioned comfort, this cookie is built on our signature sourdough starter for extra depth and a tender bite. It’s packed with hearty oats, warm cinnamon, and soft, juicy raisins that caramelize slightly as they bake. The edges turn golden and crisp while the center stays soft, making every bite nostalgic, homey, and just a little bit irresistible.
