A cookie exchange is a fun social event where friends, family, or coworkers gather to share homemade cookies. Each participant bakes a batch of cookies and brings them to the gathering. The idea is to exchange cookies so everyone leaves with a variety of treats to enjoy. During the event, participants typically display their cookies on a table, allowing others to sample and choose their favorites. After tasting, everyone fills containers with different cookies to take home. This festive activity is popular during the holiday season and encourages creativity in baking while fostering community spirit.
