Preheat the oven to 350°F (175°C) and grease a 9x13-inch baking pan.
In a large bowl, mix applesauce, sugar, oil, eggs, and vanilla.
In another bowl, whisk flour, baking soda, baking powder, cinnamon, nutmeg, cloves, and salt.
Gradually combine wet and dry ingredients.
Fold in walnuts or raisins, if desired.
Pour batter into the prepared pan and bake for 30-35 minutes.
Cool completely before serving or adding frosting.
