Preheat the oven to 350 degrees. Grease and line two 9 inch cake pans with parchment. In a stand mixer combine sweet potato, both sugars, oil, butter, vanilla, and eggs. Add the flour, salt, soda, baking powder, cinnamon, and cloves. Mix until just combined. Divide the batter between the two cake pans and bake for 25-30 minutes. Allow to cool before filling and icing.
