Cake sections are an important part of baking a cake. The term 'cake sections' can refer to TIERS, LAYERS, and TIER. TIERS are multiple cakes stacked on top of each other, usually with frosting or other decorations between them. LAYERS are thin slices of cake that are stacked on top of each other, often with a filling between them. TIER is a single cake, usually with decorations on the outside. All of these cake sections are important components of a cake and can be used to create a variety of different looks.
