Apple Pie (Pita od Jabuka)

Beautiful, simple apple pie, cake slice. The first time I tried this was when my husband's Baka made it. We had gone to visit briefly and didn't have time to stop for the usual coffee and stomach full of cakes so when we were leaving she handed me a parcel full of them. Later when we arrived home, after the long drive, I put the kettle on, even though it was nearly midnight and opened the parcel. I spotted this one straight away, among the many gorgeous delicacies and thought that it looked like it would be a bit of a lighter sort of cake to have that late at night. Well indeed it was but not if you end up having about 4 pieces of it ;) It was worth it though!
