Preheat oven to 325. Grease and flour 10 cup bundt pan or 10 inch tube. In an electric mixer paddle attachment, combine butter and sugar and beat until smooth. With mixer on low add the eggs one at a time, beating just until incorporated. Stir together the flour, cinnamon and salt, add the flour mixture to the batter, alternately with the milk, beginning and ending with flour mixture.
Pour batter into prepared pan and bake 1 hr. 15 minutes, test at 1 hour, ovens may vary. Remove after testing and cake tester comes out clean. Let cool in pan 20 minutes. Remove and cool completely. Powder sugar or drizzle if desired. I serve this cake with sugared fruit and ice cream.
