Preheat your oven to 350°F (175°C). Grease and flour a 9x13 inch baking pan, or line it with parchment paper for easy removal.
In a medium bowl, whisk together the all-purpose flour, cinnamon, nutmeg, cloves, baking soda, and salt. Set aside.
In a large bowl, cream together the softened butter and granulated sugar until light and fluffy, about 3-5 minutes. Beat in the eggs one at a time, then stir in the vanilla extract.
In a small bowl, whisk together the buttermilk and light brown sugar until the brown sugar is mostly dissolved. This will create a slightly richer liquid.
Gradually add the dry ingredients to the wet ingredients, alternating with the buttermilk mixture, beginning and ending with the dry ingredients. Mix until just combined; be careful not to overmix.
Pour the batter evenly into the prepared baking pan. Spread it out gently with a spatula.
Bake for 30-40 minutes, or until a wooden skewer or toothpick inserted into the center comes out clean. The cake should be golden brown and slightly springy to the touch.
Let the cake cool in the pan on a wire rack for at least 15-20 minutes before slicing and serving. This allows the cake to set properly.
