There’s nothing quite like a warm chocolate chip cookie fresh out of the oven—but add a little sourdough starter, and you take them to a whole new level. These sourdough chocolate chip cookies are soft and chewy with golden edges, a rich buttery flavor, and just the right hint of tang from the starter. Not only is this recipe a delicious way to use up extra sourdough discard, but it also creates a depth of flavor you can’t get with a regular cookie. Whether you’re long-fermenting them for easier digestion or baking them right away for a quick treat, these cookies are bound to become a family favorite!
