While chocolate chip cookies are good when they are slightly over-baked, with crispy edges and chewy centers, the only thing that rivals this, is when they are ooey, gooey, and under-cooked ever-so-slightly. Falls-apart-in-your-hands, under-cooked. Not, you-will-probably-die-from-salmonella, under-cooked -- just so we're clear.
This recipe for Chocolate Chip Butter Cake is great because it's supposed to be a chewy, messy, oozing delight. It's all the fun of licking the bowl spoon of the mixing bowl with less of the aforementioned risk of death or serious illness. This recipe is good enough to whip out for the family as wintry, spur of the minute dessert treat. Heck, it's good enough for you to lock yourself away in the bathroom with it and be all, "screw my family" and then eat the whole thing yourself.
