I did it. For Valentine's Day, I took a huge heart-shaped copper cookie cutter, sprayed it with Pam For Baking, and put chocolate chip cookie dough inside of it. It came out thicker than a regular cookie, almost like a brownie.
I've done it to make a cookie container, but not a cake. I rolled out the dough and used my cookie cutter (in this case a pumpkin) to cut out to shapes, one for the lid and one for the bottom. I then cut a thin strip of dough and lined the sides of the cookie cutter with it and put one of the cut out pumpkins inside the cookie cutter and blended the sides with the bottom. I'm going to make another one today, so I can take pictures of it for the website i'm building, I'll post it when I'm done. The first one was devoured before I could get a picture of it. 
fragglerock1 that sounds great! I can't wait to see the pictures when you post them.
I've never heard of it either but it sounds interesting.
I am thinkiking the batter would seep, but if you laid the cookie cutter onto the foil, then wrapped the foil up the outside of the cutter that might keep it in. Spray the inside well with oil and fill. Sounds intriguing. I am thinking it would just be easier to make a thin sheet cake and then cut out with cookie cutters though.
