Cake tier is a term used to describe a cake that has multiple layers. It is usually made up of several thin layers of cake, with each LAYER being separated by a LAYER of frosting or other filling. The term is derived from the French word for 'LAYER, ' which is 'tirer.' Cake tiers are often used for special occasions such as weddings and birthdays, and can be decorated with various decorations such as flowers, ribbons, and other embellishments. The most common type of cake tier is the three-tier cake, which consists of three layers of cake stacked on top of each other.
