From the description on the website:
Not really a cookie or a brownie, these Chocolate Chubbies from Sarabeth Levine's Sarabeth's Bakery are somewhere in between. While mixing up the super chocolaty batter I was taken with how much it resembled a brownie or cake batter, and since it was so wet, a bit concerned about how these cookies would make out after a few minutes in a hot oven. I had imagined that they would spread into a thin, chocolaty disk, but instead they barely spread at all, the little mounds of dough drying on the outside and turning into freestanding chocolate-cookie-brownies.
The baked cookies took on a shiny, almost meringue-like outer shell, and the inside was all gooey chocolate studded with chunks of walnuts and pecans. Their blobby little shapes lived up the the chubby name. Whether you call these guys self-contained brownies or cookies with the heart of a brownie, the cookie-brownie hybrid is pretty genius.
When we order preserves from Sarabeth's Bakery in NY, I will occasionally indulge with this toothsome delicacy. John doesn't like nuts, so I get to savor them all, and since they are rich and dense, they stay fresh for a very long time.
