FurFright: Baking all the things

So I have been encouraged by certain parties -- that is, all of the FurFright staff who I have given baked goods to since last year -- to actually sell my cupcakes and cookies at the convention. This is possible because I have a business license and can follow the rules of a farmers market (instead of having to worry about health code violations), and has been approved by the Folks In Charge.

The questions left, then, are two: What specifically do I sell, and how much do I sell it for?

Obviously, cookies and cupcakes and brownies (and other bar cookies) are what I'm going to be making...but which ones? There are so many types. What homemade baked goods are your favorites?

And, if you were at a convention and given the option of baked goods, how much would you be comfortable paying for them? It can't break the bank for my customers, but I'd like to make a bit of profit, as well (the supplies I'll need for distribution -- boxes, etc. -- will actually probably cost me more than the baking supplies).

Any input is greatly appreciated!
