A cookie swap is a fun social event where friends, family, or coworkers gather to bake and exchange cookies. Each participant prepares a batch of their favorite cookies and brings them to share. This way, everyone gets to enjoy a variety of treats without having to bake multiple kinds themselves. During the event, participants typically display their cookies on a table, allowing others to sample and choose which ones they would like to take home. Cookie swaps are popular during the holiday season, often fostering a sense of community and creativity among those involved, making it a delightful way to celebrate with friends and family.
