I tried them and did not like the stuff on the outside,but I do think they have them at scuttles or I may have mispelled it but it is in the Magic Kingdom.
They used to sell them at Min and Bill's Dockside Diner in DHS, but the last 2 times I checked they weren't there. You can always check and see if they're back.
Not sure where you live, but in the Philly/NY area, they sell them in most convenience stores, with cream cheese or other fillings.
Also available in the grocery stores - boxes of 6 - frozen to heat and eat at home.
The outside is almost like a graham cracker dust. I ordered one and was disappointed that it was sweet, but then it started to grow on me and now I crave them as soon as we land in Orlando!!!
