The Evolution & Variety of Cookies Anzac Biscuit – This is an Australian army biscuit, also known as an Anzac Wafer or an Anzac Tile . They are essentially a hardtack biscuit with a long shelf-life and a substitute for bread. The biscuits are very hard, and soldiers preferred to grind them up and use them as porridge. Today, they are known as Australia’s National Biscuit. The recipe for these biscuits can be traced back to Scotland during the Scottish immigration to Australia and New Zealand in the early 1800s.
