Pre-heat the oven to 150c
Chop the butter into small pieces and rub together with the flour in a mixing bowl until you get small crumbs
Add the sugar to the bowl and mix it together to make a dough
Wrap the dough in clingfilm, and place in the fridge for 30 minutes
Roll out until they are a few centimetres thick and cut out into shapes and place on baking parchment on a baking tray
Bake in the pre-heated oven for 7-10 minutes - keep checking to make sure they don't overcook, all ovens can be different
Once cooked, leave to cool on a wire rack
