Baking brownies from the inside out

brownies. They're delicious [music] but polarizing. Some like the soft and delicious center. Others like the edges, which are hard and tar kind of thing you might ask your doctor about. [music] But if you're really into that, they actually make a pan with this crazy shape which cooks [music] the entire brownie all edges. And I've always

wondered if there's an all edge pan, why [music] isn't there a no edge pan? It seems like the kind of thing that should exist, but it doesn't. What would it even look like? a brownie [music] sphere floating the brownie in midair or a four-dimensional hyper brownie tesseract pan. I decided it's time to find out.

And going into this project, I thought it wasn't going to be that bad. Like, how hard could it be to make a brownie pan? But it turned out to be a lot deeper rabbit hole than I was expecting. There was so much machining and baking. Then somehow electronics and software got involved, and I spent way too much

time trying to impress my wife. But in the end, we have some pans unlike anything [music] you've ever seen. So, join me on my quest to find out what would an [music] edgeless pan even look like. The first thing we got to do is get on the same page about what a brownie edge

even is. My wife thought I meant something like the edges of a cube, but that's not quite what I'm talking about. I think a better term would be the brownie boundary. Basically, the outer surface of the brownie, especially where it's touching the [music] pan, which tends to be the chewier, tough part. But

I think if we started asking for the boundary of the brownies, people would probably think there's something wrong with you. So, we're just going to call them edges. And the reason the edges are tougher is because of heat transfer. When you put brownies in the oven, it's super hot and they're cold. Heat energy
