Preheat the oven to 350°F.
Grease and line three 8 inch metal cake pans. If you only have one or two, no problem, you can bake the layers in batches. To line the pans, place a sheet of parchment paper under a pan, and trace the bottom with a pen, cut out the circle, and set it inside the greased pan for a perfect fit.
In a medium bowl, whisk together the flour, baking soda, kosher salt, cinnamon, ginger, nutmeg, and cloves. Set aside.
In a large bowl, using a hand mixer or stand mixer 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 evenly into 3 cake pans, spreading it out evenly.
Bake two cakes at a time for 17 to 20 minutes, or until a toothpick inserted in the center comes out clean. Let them cool for a bit, then place a plate over the pan and flip it to release the cake. It should come out easily once it’s slightly cooled.
