Thoroughly spray a 10 inch bundt pan with non-stick cooking spray
Preheat oven to 325 F
Using an electric mixer, beat together oil and sugars
Add in eggs and vanilla extract
Slowly add in flour, baking soda, salt and spices, followed by the apple slices. Batter will become VERY thick - If you feel that the dough is too thick for your mixer to handle, use a spoon or your hands to continue mixing in the flour
Pour batter into bundt pan and cook for 60-65 minutes, or until toothpick inserted in the middle comes out clean
Allow to cool completely in the bundt pan before turning pan over on top of a plate to remove cake. The cake should slip out with little effort to remove it once it's cooled
Slice and enjoy!
