King Cake is a traditional dessert that is popular during the Mardi Gras season in New Orleans. It is a sweet, circular cake that is typically decorated with purple, green, and gold icing to represent the colors of Mardi Gras. The cake is often filled with cinnamon, cream cheese, or fruit fillings, and a small plastic baby figurine is hidden inside. The person who finds the baby in their slice of cake is said to have good luck and is responsible for hosting the next King Cake party.
