Well, it sounds a lot like Apfelstrudel (which is actually Austrian), I think you have adopted it and call it apple stroodle or something ;D. Even if it isn´t, any sort of apple pie (especially if it´s warm) is hugely popular here with custard or vanilla ice cream. I think it is popular everywhere in Germany and in other countries as well.
It´s not quite my cup of tea, somehow I´m not such a fan of apple, and if I had a whole slice, I think I´d get a stomach ache. But one or two spoonfuls are delicious, especially with ice cream. I used to love custard, but I don´t as much anymore.
