Afghan Biscuits
New Zealand's classic chocolate biscuit: a buttery cocoa dough crunchy with cornflakes, topped with chocolate icing and a walnut half.
Method
Preheat the oven to 180 °C (160 °C if fan-forced) and line a baking tray with baking paper. Take the butter out of the fridge about 30 minutes ahead: it should dent easily when pressed but not look oily.
ovenPut the softened butter and sugar in a bowl and beat with an electric mixer or a wooden spoon for , until the mixture is pale and fluffy.
Add in this stepButter, softened 100 gSugar 45 g
Sift the flour and cocoa over the butter and mix with a spatula until no dry flour is visible. Add the cornflakes and fold them in gently; a few will break, but leave plenty of pieces for crunch. The dough will be stiff and a little crumbly.
Add in this stepPlain flour 90 gUnsweetened cocoa powder 13 gCornflakes (plain, unsweetened) 30 g
Scoop heaped tablespoons of dough (about 25 g each), squeeze each lightly in your hand so it holds together, and place them on the tray 4 cm apart. Flatten slightly with your fingertips to about 1.5 cm thick; they hardly spread.
Bake on the middle shelf of the oven for , until the tops look dry and the edges feel firm when touched lightly. The dough is already dark, so don't wait for browning. Leave on the tray for 5 minutes (they are fragile while hot), then move to a rack and cool completely.
ovenFor the icing, sift the icing sugar and cocoa into a small bowl, add the very soft butter and the hot water, and stir until thick, smooth and glossy. It should slowly hold its shape on the spoon: add a few drops of water if it is too stiff, or a little icing sugar if it runs.
Add in this stepIcing sugar 60 gCocoa powder (for the icing) 2 tspButter, very soft (for the icing) 10 gHot water 15 ml
Spread about a teaspoon of icing over each completely cooled biscuit and press a walnut half into the centre. Leave for until the icing has set.

Cook's tip
Icing warm biscuits makes it slide off, so wait until they are cold. Crushing the cornflakes lightly with your hand is fine, but don't blitz them or the crunch disappears. Stored airtight, they keep for a week.
Cooking it at camp
Bake them at home and pack them in a rigid container so the icing isn't crushed; in hot weather keep them in the cooler so the icing doesn't melt. Without an oven you can bake a small batch in a heavy lidded pan on the lowest camp-stove flame, but the bottoms brown faster, so check after 8 minutes.
