Ugh, I was right about to line my brownie tray with baking (parchment) paper when I realized we're out. Fellow bakers: would you just grease the tray or would you substitute aluminum foil for the baking paper?
@stephanieburgis It's probably too late but I wouldn't use foil (it tends to get caught in the brownies).
Instead I'd butter the pan and then dust with cocoa. Or flour if you don't have enough cocoa handy.
