Preheat the oven to 320°F. Sieve icing sugar, flour and cornflour into a bowl. Add butter and Heilala Vanilla Paste. Mix until a crumbly dough forms. Tip onto a lightly cornfloured bench and knead until smooth. Roll out and cookie-cut into circles. Place slightly apart on a non-stick tray. Bake for approximately 20 minutes or until starting to turn lightly golden While cookies are still hot, brush with Heilala Vanilla Syrup and sprinkle with Heilala Vanilla Sugar.
