Chocolate chip cookie cake
 

I want to make some chocolate cake, but I don't have cake mix; I only
have a package of that Nestle chocolate chip pre-scored cookie dough -
the kind that you just break apart into little squares and put on a
cooking tray and bake at 350°F for 30 - 40 minutes. Anyway, I was
thinking I would just put the whole piece of cookie dough (without
cutting it) in the oven, and then just put some chocolate icing on it.
My mom thinks it's a good idea. Any thoughts?

Thanks
