Sheet cake
A sheet cake or slab cake is a cake baked in a large, flat, rectangular cake pan. Sheet cakes can be grouped into two broad categories.
Sheet cakes are usually deep, although they are sometimes deep. These single-layer cakes are frequently frosted, with decorations and ornamental frosting along the borders and the flat top surface.
These cakes are commonly available pre-made in supermarkets and bakeries and tend to be inexpensive due to their simple manufacturing process. There are many brands that sell boxed cake mixes that can be baked as sheet cakes, including Betty Crocker, King Arthur Flour, and Duncan Hines.
Flavors
They may be made in any flavor, with chocolate and vanilla being the two most common. Commonly made in the home with boxed cake mixes, they can come in a variety of additional flavors or with batter mix-ins, such as sprinkles and chocolate chips. Sheet cakes are made from a single continuous piece of cake, or, for very large cakes, several sheets of cake placed side by side so that it looks like a single continuous piece of cake. Nuts, chocolate chips, coconut flakes, or other toppings can be sprinkled over the top.A layer cake may be made from a sheet cake that has been split, filled with jam or icing, and frosted.
Size
Cake sizes are named after the size of pan that the cake is baked in. Sheet cakes, in general, are usually deep, though a some recipes call for a thin sheet cake of 1 inch depth.In American sizing, the full-size sheet pan is, which is too large for most home ovens. A half sheet pan is half that size, or about. Quarter sheets are. The half sheet is approximately the same size as the largest mass-market sheet cakes found in supermarkets, and the quarter sheet is a common size for rectangular, single-layer cakes.
A quarter-sheet usually results in 16 to 24 servings of cake.
