An Ice cream cake consists of a cake that incorporates ice cream. A popular form is a three-layer cake, with a layer of ice cream between two layers of cake.
In a typical assembly, the cake component is baked in the normal way, cut to shape if necessary, and then frozen. Ice cream is shaped in a mold as appropriate, and these components are then assembled while frozen. Whipped cream is often used for frosting, as a compliment to the two other textures, and because many typical frostings will not adhere successfully to frozen cake. The whole cake is then kept frozen until prior to serving, when it is allowed to thaw until it can be easily sliced but not so much as to melt the ice cream.
It is related to a Baked Alaska in that it incorporates ice cream. Unlike a Baked Alaska, however, the ice cream never goes into the oven.
Ice cream cake is a popular party food, often eaten at birthdays and weddings, particularly in North America and Australia. It is not as well known in Europe.
Ice cream cake was originally made from biscuits and cream. Victorian era desserts called bombes consisted of ice cream and fruit in decorative molds. Sometimes these desserts were lined with cake or biscuits. Ice cream cake recipes dating to the 1870s have also been found.
It is common for ice cream cake to be used as a birthday cake during birthday celebrations. At times, when Ice Cream Cake is not available (especially when dining out), Fried Ice Cream (a common dessert found at Asian restaurants) can be used as an alternative to the cake variety.
