Remove the sugar cookie dough from the fridge and roll out on a floured surface or between two pieces of baking paper. Ensure an even thickness throughout the rolled out dough.
Use cookie cutters to cut out your desired shapes and place these onto baking trays line with baking parchment paper. Bake the cookies in the oven for about 15 minutes or until a light golden brown. Use an oven thermometer to test the temperature of your oven to ensure the cookies don't burn on the bottom.
Remove the cookies from the oven and allow to cool. Decorate with a dusting of icing sugar and arrange the cookies on a platter in the shape of a Christmas wreath, place a bow in the centre of the wreath and enjoy!
