Preheat oven to 350 degrees F (175 degrees C). Grease and flour one 9 inch round cake pan.
In a medium bowl, stir together the flour, baking soda, spices and salt. Set aside.
In a large bowl, cream together the butter and sugar until light and fluffy. Beat in the eggs one at a time, then stir in the vanilla. Beat in the flour mixture alternately with the buttermilk.
Spread evenly into the prepared pan. Bake for 30 to 35 minutes in the preheated oven, or until a toothpick inserted into the center of the cake comes out clean.
Cool in the pan for 10 minutes, then turn out onto a wire rack and cool completely.
