Preheat the oven to 350 degrees F. In a large bowl, mix together the applesauce, oil, sugar, apples, and vanilla in a bowl.

Then add the flour, salt, baking powder, cinnamon, raisins or vegan chocolate chips (if using), and walnuts (if using), and whisk until thoroughly combined.

Pour the batter into a greased muffin pan and bake for 25 to 30 minutes, or until a toothpick comes out clean.
