Preheat oven to 350°F (175°C). Grease and flour a 9x13 inch baking pan.
In a medium bowl, whisk together the flour, baking soda, salt, cinnamon, ginger, cloves, and nutmeg.
In a large bowl, cream together the softened butter and granulated sugar until light and fluffy.
Beat in the eggs one at a time, then stir in the vanilla extract.
Gradually add the dry ingredients to the wet ingredients, alternating with the buttermilk, beginning and ending with the dry ingredients. Mix until just combined.
Pour the batter into the prepared baking pan and spread evenly.
Bake for 30-35 minutes, or until a wooden skewer inserted into the center comes out clean.
Let the cake cool in the pan for 10 minutes before inverting it onto a wire rack to cool completely.
Notes
This spice cake is delicious on its own, or can be served with a simple glaze or frosting. It pairs wonderfully with coffee or tea.
