There have been a number of flavours of Walnut Whip over the years, including coffee and maple flavours, but currently only vanilla is widely available. The original Walnut Whip contained a half-walnut placed inside the cone on the thick chocolate base, rather than on top. It was later marketed with an extra walnut on top, and subsequently the walnut inside was removed to leave one walnut outside. The chocolate cone itself and the vanilla fondant filling have altered in recent years; the cone previously had a more pronounced tightly knit rough surface and the fondant was more dense.  The texture of the outside surface is a skeumorph: the original whips were moulded as a spiral cone of extruded chocolate; as the extrusion was ridged and twisted during moulding, this generated the knitted surface as a result of the process. When the whips switched to being hollow moulded instead, in the late 1970s, the original surface was recreated, although it now had no function other than decoration.
