I've made the chocolate chip cookie cakes several times. When you put the dough on the pizza pan leave a hole in the middle (the dough is in the shape of a ring) so that when it spreads you won't have a big hump in the center.
If you need a recipe PM me.

I use my baking pans for my cookies. I cut a piece of parchment the size of the pan, and then press the dough down on top of it. I then chill the pan for about 30 minutes, then bake at 375. When I am ready to flip it out, I don't have to worry about it sticking. I have make cookies up to 20" and this seems to work for me.
