An icebox cake (American) or chocolate ripple cake/log (Australian) is a dessert consisting of whipped cream and chocolate wafers. The back-of-the-box recipe on Nabisco Famous Chocolate Wafers indicates that the wafers are stacked to form a log with whipped cream cementing them together, and then the log is laid on its side. A second log is formed and the two are set side-by-side and more whipped cream covers the exterior. The cake is then left overnight in the refrigerator (or "icebox"). The wafers absorb moisture from the whipped cream and the whole can be served in slices. The dessert is usually served by cutting it into slices at a 45-degree angle, so bands of chocolate and cream are visible across each slice. The traditional wafers are the thin and dark Nabisco Famous Chocolate Wafers, but they may be hard to find in some areas so other cookies are sometimes substituted.
