Preheat oven to 350 degrees. Grease and lightly flour a 9-inch round or square cake pan.
In a medium bowl whisk together flour, salt, baking powder, baking soda, cinnamon, nutmeg, ginger, allspice, and cloves.
In a second, larger bowl combine brown sugar, oil, apple sauce, grated apple, eggs, and vanilla and mix thoroughly.
Mix dry ingredients into wet ingredients until incorporated.
Pour into prepared pan. Bake in preheated oven for 20-25 minutes until a toothpick inserted in the center comes out clean.
Allow cake to cool at least 20 minutes before gently turning out onto a plate to cool completely. Once completely cooled, frost, sprinkle with cinnamon-sugar if desired. Cut, and serve or cover and store at room temperature up to three days or in the fridge in an airtight container up to 1 week.
