Layer cakes are multi-tiered cakes made by stacking several layers of cake, often separated by frosting or filling. Each layer can be made from different flavors, allowing for a variety of tastes in one dessert. Commonly, layer cakes are frosted on the outside and decorated with various toppings, such as fruits, nuts, or chocolate. These cakes are popular for celebrations like birthdays and weddings, where their height and decoration can create a stunning visual impact. Famous examples include the chocolate layer cake and red velvet cake, both of which are enjoyed for their rich flavors and appealing appearance.
