All I can say is W - O - W !!
This pan is the best. I've actually purchased it here and I've had it for about a year now. Honestly I have only used it for brownies. If you are anything like my husband and myself, you like your brownies to be edges and your brownies to be done, not gooey. well, here is the pan for you. This makes all edges. There are actually a bunch of recipes here. Lasagna, cobbler, bar cookies, cheesecake and, of course, all kinds of layered brownie goodness. I always use a box brownie in the 9x13 size. I would think the 9x9 size would be too skimpy.
