National Gingerbread Cookie Day is observed worldwide on November 21, celebrating the deliciousness of gingerbread cookies. The day encourages people to showcase their baking skills by making gingerbread cookies, which are flavored with ginger and spices like cinnamon, cloves, and nutmeg. Gingerbread has a rich history, dating back to at least the 11th century in Europe, with the first documented gingerbread men appearing at the court of Queen Elizabeth I. In the United States, gingerbread cookies are particularly popular during the holiday season and are often decorated with royal icing. Celebrations may include baking and decorating cookies with friends, hosting gingerbread design contests, or enjoying store-bought cookies with beverages like milk or hot cider. Participants are encouraged to share their creations on social media using hashtags related to the holiday.
