Here is the recipe that I used to make my German Apple Cake from the Allrecipes.com collection. And here is my blog from last year with the changes I made the first time I baked it. Since then I have made it more or less just like the recipe and it always turns out great.
I always use a bundt pan just because it is so pretty, but you do need to heavily spray and sugar the pan to keep the cake from sticking. And it will need to bake for about 55 minutes. I have made it with half white flour and half whole wheat flour, and that is also good.
