For those who only like edges, I will share my secret. My DH only likes the edges, and even then, really prefers the corners. He would NEVER eat the centers. So, for the last 27 years, I have made my brownies in my regular-sized muffin tin. I get 12 somewhat larger than average round brownies from a boxed brownie mix, all with edges, and no cutting required. DH loves the brownies with edges all around. Just watch them the first time or two you are baking them as they may cook just a bit quicker than usual.
