Neapolitan wafer

Neapolitan wafers are a wafer and chocolate-cream sandwich biscuit, first made by Austrian company Manner in 1898.

Using hazelnuts imported from Naples, Italy, to make the hazelnut-flavoured chocolate cream filling, they have five wafers and four layers of cream in their 49 millimetres (1.9 in) x 17 millimetres (0.67 in) x 17 millimetres (0.67 in) biscuit size. The basic recipe has remained unchanged to the 21st century.

Manner still sell the biscuits in blocks of ten. Many other companies have copied the idea, most often coating the bar in chocolate.
