Preheat oven to 325º. Grease and generously flour a Bundt pan, tapping out excess flour. (Alternative, cake can be baked in a square glass pan, which should also be greased and floured.) Whisk together dry cake ingredients (through ground cloves). In a large bowl, beat sugar with oil until blending; beat in eggs 1 at a time. Add 1/3 of the dry ingredients, incorporating, then 1/2 of the buttermilk. Repeat, then add last third of dry ingredients. Pour into prepared pan, and bake about 35 minutes, until tester comes out clean.
