How about "special" brownies? The college kids will love em!
Seriously, I had pineapple upsidedown cookies... they were GREAT! I think that they were more like cookie sized cakes. They had the pineapple ring on them, and thats how big they were. They were soooooooo GOOD!
Then there is the best chocolate cookie in the world. You take two cookies (i like vanilla flavor for this...). You take slightly metled milk chocolate and spread it think on top of one cookie. Then before the chocolate get hard you slap the other cookie on top of it!
Its important that the cookies are somewhat soft.
Im not much of a baker... thats all I can think about for now.
