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 I am not an expert level baker but I’d go with greasing the pan. I’d be concerned about foil getting stuck to your brownies and aluminum is not the safest stuff.
