Preheat oven to 350 degrees F. Grease and flour a 9x13 pan.
In a medium bowl, combine apples and sugar, stirring to combine. Set aside.
Egg Mixture: In a medium bowl, add eggs, melted butter, and vanilla. Mix well to combine.
Flour Mixture: In a large bowl, add the all purpose flour, baking soda, cinnamon, and salt. Whisk to blend.
Alternately stir in the flour mixture and egg mixture to the apple/sugar mixture. Start and end with the flour mixture. (We did three additions of the flour mixture and two additions of the egg mixture). *Stir just until combined- be careful not to overmix.
Finally, fold in the chopped pecans. Pour the batter into the prepared 9x13" pan.
Bake at 350 degrees F for 40-45 minutes or until an inserted toothpick comes out clean or with just a few crumbs attached. Allow to cool on a wire rack for 5 minutes before turning out. *If the cake begins to become more brown than you'd like, lightly cover pan with aluminum foil.
