Preheat oven to 350°F.
Butter your cake pan, and then coat with flour, so the cake comes free later.
In a mixing bowl, combine the flour, salt, cinnamon, nutmeg, baking powder, and baking soda. Stir or whisk to combine.
In your mixer's bowl, combine the lightly beaten eggs, sugar, oil, and pumpkin puree. Start mixing on medium speed to combine.
Start slowly adding the dry ingredients to the mixer, a little at a time, combining until it's all a smooth batter.
Pour the batter into your cake pan of choice.
Bake for 45-60 minutes. If you're using a shallower pan, 35 minutes might be enough. Bake until a toothpick, inserted into the center, comes out clean.
Set aside to cool for icing.
