Probably an obvious choice, but I love Macaroons (or how they are spelled.?)
I love Marshmallows! either, just as they are, or grilled or in hot chocolate.
And always my favorite: Chocolate. Preferably Marabou's regular chocolate. ^^v
Oh, and a favorite for meetups is: Cheesecake. ^^
Yeah, can't pick just one, there is alot of delicious things in the world. :)
