Here is the original as found on chefs.com --I modified it by adding some reduced fat sour cream in place of some of the oatmeal (i didn't have enough of the instant oatmeal to make a full 1 cup as called for). They are super-moist and I used Ghirardelli chips so the flavor was excellent. I also used only 1/2 cup butter whereas the original recipe called for 2/3 cup, then I added canola oil to make 2/3 Cup but it still tasted fine. I also added 1/2 cup of dark cocoa to make it even richer. They're slightly chewy although it wasn't chewy as some brownies; it might be chewier if you baked it more than 25 minutes, I don't know.
