Sheet cake

A sheet cake or slab cake is a cakebaked in a large, flat, rectangular cake pan. Sheet cakes can be grouped into two broad categories.

Sheet cakes are usually 2 inches (5 cm) deep, although they are sometimes 3 inches (8 cm) 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.
