The Costco Special Order 1/2 Sheet Chocolate Cake is a custom-decorated celebration cake made fresh in the Costco in-warehouse bakery. It features a moist chocolate cake base with chocolate mousse filling, finished with smooth chocolate buttercream frosting throughout.

The half-sheet measures approximately 12 inches by 16 inches and serves approximately 48 people, making it well-suited for birthdays, graduations, anniversaries, and large gatherings. This cake is available by special order only and must be placed in person at your local Costco bakery at least 48 hours in advance, with an active Costco membership required. Customization options include a selection of designs such as roses, balloons, or occasion-themed decorations, along with personalized text in your choice of color.

After pickup, the cake can be refrigerated for 3 to 4 days or wrapped and frozen for up to three months.
