These were amazing!! I used what I had at home, so I had to use extra flour-2tblsp-instead of cornstarch, and I used 1/2 bag PB chips, and 1/2 bag milk choc chips, but was still amazing! Hubby said they were awesome, and WAY better than a box. I've never made from scratch brownies, and I fond these to be super easy, super moist, and super rich-Richy Rich rich-but they totally hit the spot. Definitely make again!
