Step-by-step instructions

1. 1

   Whizz the flour and butter until the mixture looks like breadcrumbs. Add the sugar, vanilla and egg yolks and whizz to a smooth dough. Roll the dough on a lightly floured surface into 2 sausage shapes about 4-5cm in diameter. Wrap in cling film and chill for at least 30 mins.

2. 2

   Heat oven to 180C/160C fan/gas 4. Cut the dough into 4mm-thick slices and arrange on baking sheets, spaced slightly apart. Bake for 15 mins or until pale golden. Transfer to a wire rack to cool.

3. 3

   Heat icing following pack instructions. Add a little food colouring to each tub and ice half the cookies in yellow, and decorate with red, then ice the other half red and decorate in yellow. Leave to dry.
