• 175g butter, softened
• 100g caster sugar
• 1 medium egg yolk
• 250g plain flour
• 50g royal icing sugar, made
• up as instructed
• Silver balls and ribbon

1 Preheat the oven to 180C/ 160C Fan/Gas 4. Line 2 baking trays with baking paper. Beat the butter and sugar until creamy. Beat in the egg yolk and add the flour and mix to a smooth dough. Gather together with your hands, wrap in clingfilm and chill for 30 minutes.

2 Roll out the dough between two sheets of clingfilm to the thickness of a £2 coin.

3 Cut out into stars or trees or just rounds and put on the baking trays, leaving a small gap around the biscuits. If they are to be hung on the tree make a small hole for the ribbon.

4 Bake for 15 minutes, leave for 10 minutes and then cool on a wire tray. Pipe or drizzle some icing onto the biscuits and decorate with silver balls. Allow the icing to set before storing.
