Preheat oven to 325 degrees. Generously grease and flour a 10-inch tube pan. You can use a Bundt, but this is a sticky cake so make sure it is nonstick or very well greased. Alternatively, you may use a 9x13 inch pan but the bake time might be shorter.
Stir flour, sugar, baking soda, salt, and spices together in a mixing bowl.
In a a mixing bowl, whisk together oil, eggs, buttermilk, vanilla and fig preserves.
Add liquid mixture to flour mixture and stir until blended.
Pour into pan and bake at 325 for about about 1 hour (check at 45 minutes) or until cake tests done or reads a little over 203 degrees F. Let cool in pan for about 20 minutes, then carefully loosen with a knife. Don't remove from pan yet. Let cool completely, then turn from pan. Pour glaze over cake while warm.
Buttermilk Glaze
Combine all glaze ingredients except for the vanilla in a small saucepan. Bring to a boil. Remove from heat, let cool slightly, then stir in the vanilla.
