Sheet cakes are simple one layer frosted cakes that are often prepared for celebrations that involve a dozen or more participants. The sheet cake has become a popular option for birthday parties, celebrations in the workplace, and family reunions and anniversaries. Typically, layer cakes of this type are prepared in three different sizes, depending on the number of servings are needed for the event.

For smaller gatherings, the most common size of sheet cake is the quarter sheet. This simple one layer cake is rectangular in shape and will provide ample servings for twelve to twenty people. Celebrations around the home are often ideal for a cake of this size. The half sheet cake is twice the size of the quarter sheet, and will provide thirty to fifty servings. Often, cakes of this size are ideal for office gatherings.

As a third option, the full sheet cake provides an ideal solution for a sweet at a larger gathering. Generally of a size that will provide between sixty to a hundred servings, the full sheet cake is an ideal solution for larger events, such as holiday celebration involving multiple departments at work, or family reunions.

Preparing a sheet cake is not very different from baking any type of cake. Instead of using standard round cake pans and baking multiple layers, a sheet or jellyroll pan will be used to bake a single layer. The ingredients that are used in preparing the batter for a sheet cake are also the same as with any cake recipe, but will of course involve using larger quantities. Some special handling may be required when turning the layer out of the baking receptacle, since the cake is larger.

Today, many people choose to use the services of a supermarket bakery when a sheet cake is needed. Generally, there are a wide range of prepared sheet cake designs that can be quickly adapted to any occasion in a short period of time. It is also possible to order the sheet cake in advance. When this is done, it is often possible to have the colors and design of the cake customized especially for the event.
