Directions say 45-50 minutes. I set the timer for 45, then didn't hear it when it went off. Ellie came to get me an unknown amount of time later, at which point they appeared done. (The toothpick test is a bit inconclusive because of high chocolate chip content.)

Oven temp was correct. We've discovered that the dial is 25 degrees off, so I am now able to account for that.

Last time I made brownies, the oven was too cool and I had to put them back in there quite a few times (including oops-forgetting them through all of dinner). Those came out okay.

So I am thinking the directions should say 50-55 minutes, if not longer.
