Recipe Tips & Notes

  • The bake time for these can be surprisingly tricky, because there’s no sure way to tell when they are done. You can’t do the toothpick test, because a truly fudgy brownie (like these) will leave chocolate residue on the toothpick. And you can’t assume that it’s done baking just because the edges and tops look done. However, I’ve baked these brownies a zillion times, and I think I’ve got the baking times down pretty well. Follow these times and you should be just fine:
    • 8×8 metal pan – 30 minutes
    • 9×9 metal pan – 25 minutes
    • 9×13 metal pan – 18 minutes
  • I really like to use Ghirardelli 60% cacao dark chocolate chips. They are huge, and they make the whole brownie taste like dark chocolate. Yum!
