Preheat oven to 350 ℉ and grease or coat with cooking spray a 10-inch tube pan or cake pan.
Combine flour, baking powder, baking soda, cinnamon, mace or nutmeg and salt in a bowl. Set aside.
Whisk oil, sugar, brown sugar, eggs, and vanilla until combined. Pour the wet ingredients into the dry ingredients until mixed. Then, fold in the chopped apples, raisins, and nuts.
Bake for 50-60 minutes, or until a toothpick inserted in the middle of the cake comes out clean. Baking times will vary depending on the pan used. Cool the cake before slicing and topping with additional chopped nuts before serving.
