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 sample a variety of cookies and take home an assortment of treats made by others. During the event, everyone typically places their cookies on a table, allowing others to taste and enjoy them. Participants may also share recipes and baking tips. This festive activity is popular during the holiday season but can be enjoyed any time of year, fostering community and creativity.
