You can get them at the kiosk outside the American pavillion as the previous poster mentioned at Epcot and at MK I believe unless they took them off the menu, Sleepy Hollow over the bridge from main street over into Liberty Square on the castle side.
Also be careful if its windy outside. We were at Epcot this past Saturday. It was so windy. We were standing in line to get our funnel cake. There was a lady in front of us. When the CM handed her the plate through the window, the wind got hold of that funnel cake and it took off like a flying saucer across the park. I never laughed so hard. Needless to say the nice CM gave her another one and she held on to it for dear life.
