Combine flour, salt, and 1/2 teaspoon of cinnamon; stir into the creamed mixture to form a stiff dough. Shape dough into 1 inch balls. Mix together 120g confectioners' sugar and 1 teaspoon cinnamon; roll balls in cinnamon mixture.
Bake for 15 to 20 minutes in preheated oven, or until nicely browned. Cool cookies on wire racks.
