Peel and slice apples.

Combine apples and sugar in a large mixing bowl.

Mix well to coat apples with sugar.

Stir in oil, nuts, eggs, and vanilla.

Combine dry ingredients (flour, baking soda, cinnamon, salt) in a separate bowl.

Add dry ingredients to the apple mixture and blend well.

Spray a 9x13 inch pan with cooking spray.

Spoon the batter into the prepared pan.

Bake at 350°F (325°F if using a Pyrex pan) for 50 minutes to 1 hour.

Check for doneness at 50 minutes; the center should be barely set and edges still soft.

Cool in the pan before cutting.

Cut with a sharp knife.

Use a pancake turner to remove the slices.
