MK-ice cream cookie sandwiches at Main Street Bakery (followed by a piece of carrot cake, also from there)
Epcot-peach tart at the French Bakery (as a second choice, I'll settle for anything from there)
Animal Kingdom-this is the place fro a Micky Bar
MGM-can't really call it my favorite since I haven't tried one, but I saw a dessert pretzel at Min and Bill's Dockside Diner, it looked like hot apple filling, so I have to try it next time. Looked like it may become my favorite.
