Heat oven to 350 degrees. Mix apples and sugar thoroughly. Add oil, nuts, eggs and vanilla. Mix dry ingredients together and add to apple mixture. Bake in a greased 13x9 inch pan for 35-45 minutes.
This cake is one of those that you can pretty much finish and serve however you like. If you want to frost it, a sour cream frosting is good. Whipping cream or ice cream go very well with it, too. My favorite way to eat it, though, is with no frosting at all.
Although any variety of apple works in this cake, I like to use a combination of varieties, particularly Golden Delicious, Criterion, and McIntosh.
