Preheat oven to 150oC. Line two trays with baking paper.
Using an electric beater, beat the butter and sugar in a bowl until pale and creamy. Mix in vanilla essence.
Slowly add the flours, beating on low speed until almost combined. Use your hands to bring the dough together. Transfer to a floured surface and knead gently until smooth.
Gently roll out to 1cm thickness. Cut out desired shape and carefully lift onto tray.
Bake for 20 minutes or until lightly golden.
