Apple Cider Pound Cake

In a large mixing bowl, cream sugar and butter. Add eggs, one at a time, beating well after each addition. Stir together all dry ingredients; set aside. Combine cider and vanilla. Add dry ingredients alternately with cider mixture to batter. Mix until well blended. Spoon into a greased 10-in. angel food cake pan or fluted tube pan. Bake at 325 degrees F for about 1 hour and 10 minutes or until cake tests done. Meanwhile, combine all icing ingredients in a saucepan. Bring to a boil; reduce heat and simmer 10 minutes. While cake is warm, drizzle 1/2 of the icing over cake. Serve remaining icing over individual cake servings, if desired.
