From the photos and video I have seen, its like 2 or 3 smaller ones at Casey's and it looked like powdered sugar on them, maybe?
@yulilin3 can you chime in?
I believe the one at Epcot is just 1 big one and maybe it does not have powdered sugar?
I have not had either. I am just going off research I have done because I plan to try 1 or both in June.
