I wish I had another full tray of these guys.
My demon-oven did not overbake these. In fact, I gave them an extra seven minutes, and they were still a bit underdone. It wasn't really a problem, but I'd suggest using one of the brownie pans that is all edges for this recipe. I'm not surprised that's what was shown on Serious Eats. BTW, I don't think I'll ever make brownies again without taking the time to line the pan. It was a lot easier than trying to pry out squares with a spatula.
