Prepare the dusting sugar by sifting at least 150g of powdered sugar into a bowl. Place aside.

Sift the flour with salt then mix it with the ground walnuts.

Mix the butter and sugar in a bowl for 5 minutes or until pale and fluffy.

Add the vanilla then incorporate the milk, spoon after spoon, mixing well after each addition.

Add the flour mixture, one half at a time, and knead just until the dough comes together.

Wrap the dough in plastic wrap and refrigerate for 2 hours at least.

Once the dough is chilled, take small pieces of dough and shape into a log that has 1cm diameter. Cut the log into approximately 5cm long pieces. Using your fingertips, shape each end of the smaller pieces to look thinner then bend the small log to look similar to a croissant or half moon.

Place the cookies on baking trays then bake in the preheated oven at 350F for 12-15 minutes or until they are just slightly golden brown.

Remove from the oven then allow to cool down in the pan for 10 minutes. Take the cookies from the pan and place them in the powdered sugar, coating them on all sides.

Remove on a platter and serve!
