This is actually a good question.
Both spellings are correct. I'm not exactly sure but I think with an 'e' means in general; with an 'a' means an individual piece.
Also, 'confectionary' is an adjective as well as a noun.

The difference is that confectionery is correct and confectionary is wrong. The word confectionary does not exist in English.
