He has been trying to make one for years, with no success, in fact with much failure, generally producing an inedible greasy mess.
Mine came out well, but I came near burning the heck out of my torso in the process of flipping it out of the pan... so I don't really see myself baking another one anytime soon.
The cake is baked upside down, to produce the caramel covered apples on the top, which involved pulling a 9" , 350 degree cast iron pan (HEAVY!!) out of the oven and flipping it's contents in one motion onto a serving plate.
The flipping went ok, but boiling sugar/butter poured out all over the counter and splashed over my front, but luckily I was wearing an over sized t-shirt, which I ripped off instantly and didn't get burned.
It made a giant mess, though.
Despite losing a good deal of the caramel topping, the cake was deemed a huge success by Rolf, so I suppose it was a good evening after all.
I used our "apfelmachine" a German apple peeling and cutting device, that is really cool and old fashioned looking, to cut the apples into uniform slices, and peel them at the same time.
I like any excuse to bust that thing out and make some uniform apple slices!
