This is from Firehouse Pizzeria, and I highly recommend it. But, if you are not going to be in Logan, UT any time soon, you can make your own at home. There is a wonderful invention called a "Skookie" that allows you to make these cookies, brownies, and pizzas in personal portions.

It might be good to cure the iron before you use your Skookie, or your food will have an interesting after-taste. But, after that, enjoy!
