Makes about 12 or more
125g butter, softened
85g soft light brown sugar
1 tsp vanilla extract
1 large egg yolk
150g plain flour
75g white chocolate, chopped or broken into small chunks
50g macadamia nuts, chopped
Preheat the oven to 180ºC/ fan 160ºC/ Gas 4.
Beat together the butter and sugar until it is pale and creamy, either in an electric mixer or by hand.
Beat in the vanilla extract and egg yolk.
Add the flour, white chocolate chunks and chopped nuts. Mix until you have a smooth dough, with the only lumps being the chocolate and nuts.
Using your hands, roll the dough into golf sized ball and lightly press each one flat on to a greased baking sheet, making sure they are spread slightly apart.
Bake for 12 minutes until golden. Remove from the oven and let cool for a couple of minutes before either eating or cooling completely on a wire rack.
