I’ve been seeing this a lot on baking mixes. Like today, I want to make brownies. The directions say “350° for metal pan, 325° for dark or coated pan\*.” Of course, that asterisk doesn’t lead anywhere. What’s a dark or coated pan? What would a glass/pyrex pan be? Why the temp difference? ---

IIRC, dark-colored pans tend to brown things more, versus a shiny metal pan. They may recommend a lower temperature to prevent burning or over-browning. ---

Well, I found [this](http://www.wise4living.com/khcookware/glass.htm): > [@](#): > > Glass bakeware dishes behave differently from metal bakeware. Porcelain glass cookware heats up and cool down more slowly and help prevent a thick crust from forming on casseroles, brownies, and other foods. Generally, to adapt a recipe from a metal dish to a glass dish, you should lower the baking temperature by 25 degrees and allow a bit of extra time in the oven. So I guess that pretty much answers that. Glass baking dishes count as “dark or coated” even if they’re neither. ---

Pyrex, glass pans makes better brownies. Just use some Pam on the bottom only. I have two pans for brownies one is an 8 inch square and one is a nine inch. If you like them thick use the 8 inch and if you get the box that says 13 x 9 never use a 13 x 9 pan. They come out wafer thin. I make those in a 9 inch square pan. I love brownies and they come out overdone in metal pans. I love brownies and even if they are mushy or stiff they are still yummy. Glass pans =350 Dark pans = 325 ---

They were extra decadent, with little mini peanut butter cups mixed in.
