Preparation time 15 minutes Cooking time 12 -15 minutes
115g/4oz butter, softened plus extra for greasing
115g/4oz caster sugar
1 egg yolk
100g/3½oz plain flour, sifted
1tsp baking powder
200g/7oz white chocolate, chopped
55g/2oz hard amaretti biscuits, crushed
Gold edible glitter for sprinkling
Preheat the oven to Gas Mark 5/190/375C and grease and line two baking trays. Using a mixer cream together the butter sugar and egg yolk until light and creamy. Add the flour, cocoa and baking powder and whisk again. Add the white chocolate and crushed amaretti biscuits and bring the dough together with your hands adding a little milk if too dry.
Pull off 15 small balls the size of walnuts and place on the baking trays with a gap between each cookie. Press each cookie down with your fingers. Bake for about 12 - 15 minutes until the cookies are golden brown. Transfer to a rack to cool using a spatula, then sprinkle with edible glitter.
