Use a fork to press down and create criss-cross lines on the cookie – first in one direction, and then in a second direction

About this Recipe
Looking for a delightful way to use your sourdough starter discard that goes beyond bread? These Sourdough Peanut Butter Cookies offer a wonderfully unique twist on a classic, perfect for any baker eager to explore new ways to bake with sourdough.
While these cookies don't boast an overt sourdough tang, the starter discard subtly enhances the overall flavor profile, creating a richer, more complex taste than standard peanut butter cookies. It’s a clever technique for adding depth without a strong sour note.
Expect a truly satisfying peanut butter cookie experience: soft, chewy, and packed with that comforting, familiar peanut flavor. The addition of sourdough discard elevates the simple ingredients, contributing to a wonderfully nuanced taste that feels both classic and special. With their inviting aroma and familiar texture, these cookies are pure comfort, especially when finished with an optional chocolate kiss. This recipe makes the most of your active or fed sourdough discard, ensuring nothing goes to waste while delivering a delicious treat.
For an extra special touch, you can add a chocolate kiss to the warm cookies right after baking, pressing it gently into the center. If you prefer, a simple sprinkle of flaky sea salt on top before baking also offers a lovely contrast to the sweetness.
These cookies are perfect for casual snacking, lunchbox treats, or sharing with friends and family. They pair wonderfully with a glass of milk or a hot cup of coffee.
