The Afghan biscuit is one of the most traditional pastries in New Zealand. It is made with flour, butter, cornflakes, sugar and pure cocoa powder. It is topped with chocolate icing and a walnut kernel pressed over the icing.
The recipe contains a high proportion of butter, a relatively low sugar content and no leavening agent. It has a soft, dense and rich texture, with a delicious crunch provided by the cornflakes.
The high butter content gives a soft melting texture and the icing compensates for the low sugar content in the dough and the bitterness of the cocoa.
