Preheat your oven to 350°F. Grease and line an 8 inch cake pan with parchment paper. I like to cut out a circle the size of the pan so it fits snuggly into the bottom. You can also use an 8X8 square baking pan, if so, line with parchment paper going up and over the sides.
In a medium bowl, whisk together the flour, baking soda, kosher salt, cinnamon, ginger, nutmeg, and cloves. Set aside.
In a large bowl, beat the eggs until well combined. Add the sour cream, vegetable oil, pumpkin puree, brown sugar, and vanilla extract. Mix until smooth and well incorporated.
Gradually add the dry ingredients to the wet ingredients. Beat the dry ingredients into the wet mixture until just combined. Be careful not to over mix!
Pour the batter into the cake pan, spreading it out evenly. Bake for 26-30 minutes or until a toothpick inserted comes out clean. Let the cake cool before frosting it. If you used a round cake pan, place a plate on top and flip it over so it slides out smoothly. If using a square baking pan, lift the cake out using the parchment paper that was up and over the sides.
