Preheat a fan-forced oven to 170ºC. Line a large baking tray with baking paper.
In a large bowl combine all the cookie ingredients, mix well then spoon 14 x large spoonfuls
onto the prepared tray. Bake for 15 mins or until just cooked.
Allow to cool on the tray for
30 mins.
To prepare the icing, combine sugar, cocoa powder and butter in a small bowl. Add 3 tbsp
boiling water and stir, adding a touch more boiling water if needed, until the mixture
becomes a smooth paste. Once the cookies are cooled, spoon 1 tsp of the icing on top of
each and top with a walnut half. Allow icing to set before serving.
