How To Make the Best Chewy Sourdough Chocolate Chip Cookies (with Discard!)

There’s something about baking cookies with sourdough that feels like stepping back in time—in the best way. These rustic sourdough discard chocolate chip cookies are soft in the middle, golden at the edges, and just kissed with that signature tang from your starter. They’re simple, hearty, and made for slow afternoons, warm kitchens, and a glass of cold milk (or strong coffee). If you’ve got a bit of discard and a craving for comfort, this recipe’s calling your name.
What is Sourdough Discard?
Sourdough discard is simply a portion of active sourdough starter that is removed before feeding your starter fresh flour and water. Some people choose to throw it out and some find creative ways to use the discard.
Tips for the Coziest Cookies
• Use discard or active starter – Both work! Discard adds a slightly more pronounced tang, while active starter makes them a bit puffier.
• Chill time = better flavor – If you’ve got time, chill the dough for a few hours or even overnight.
• Swap-ins – Try chopped dark chocolate, toasted pecans, or even a handful of oats for an extra rustic twist.
