Gingerbread Cake

3 1/2 cups all purpose flour
1 cup sugar
2 teaspoons baking soda
1 1/2 teaspoon cinnamon
1 tablespoon ground ginger
1/2 tablespoon ground cloves
1 teaspoon salt
1 cup shortening
1 1/2 cups buttermilk
1 cup dark molasses
3 eggs

Sift first 7 ingredients together.  After sifting, mix with next 4 ingredients.  Mix until batter is smooth.  Grease and flour a 9 x 13 pan.  It will fill this pan completely.  If you desire, you can sprinkle a little sugar on top or leave it plain.  Bake at 350 degrees for 45-50 minutes or until a toothpick comes out clean.  Start checking on it at about 25 minutes.
