What is a number cake?

A number cake is a sponge cut or baked in the shape of a number (or letter), topped with swirled buttercream or cream and decorated with an array of treats — macarons, meringue kisses, fresh flowers, berries, chocolate truffles and more. They're perfect for milestone birthdays.
