I don't recall exactly where I first heard about this marvelous invention. I'm just thankful that I did. Because I'm one of those people who will fight for a corner brownie. The combination of a moist, tender center and a crunchy, chewy edge is, in my opinion, chocolate perfection. But with this pan, there is nothing to fight about, because every single brownie has two chewy edges. And there is something magical about the design. The insides cook through, though the edges do not burn; the brownies do not stick, and clean-up is a snap. I bought my pan last December and have used it many times, but it still looks like it is brand-new. It came with recipes, but I haven't tried them yet because I have had such good luck with the 13 by 9 family size mixes.
I highly recommend that you treat yourself and all your chocolate-loving friends to one of these pans. In the meantime, I'm going to help myself to another brownie!
