Preheat oven to 200°C/fan 180°C/gas mark 6.
Place butter, caster sugar and Fate Low Protein All-Purpose Mix into a mixing bowl and mix.
Knead the ingredients until they bind together (add the water as needed to form a manageable dough).
Transfer to a surface lightly dusted with Fate Low Protein All-Purpose Mix and continue to knead until smooth.
Roll dough to a thickness of 0.5cm, cut into 6 biscuits with the circular biscuit cutter and place onto a lightly greased baking tray.
Cook for 20-25 mins.
Remove the biscuits from the oven and cool on wire rack.
Using the icing pen, draw antlers and eyes onto the biscuits.
Add a dab of the icing onto the bottom of the skittle and add onto the biscuit as the nose.
Allow to set and then serve.
Top Tip!
Add ground cinnamon or nutmeg to the biscuit mixture for a stronger Christmassy flavour.
