Candy Corn is primarily granulated white sugar and corn syrup. Neither of those are available in scentform which is why so many Candy Corn FOs vastly differ. Some smell like caramel, some like butter, honey, hints of almond, etc. Having tried Yanks I found it to be mostly marshmallow with just a hint of butter. Not knowing of an exact blend I'd suggest blending marshmallow, with a hint of Kettle Corn + Vanilla and see what that gets you.
