Waste Heat Cookies

My lovely girlfriend made me a slice from something close to cookie dough and chocolate and peanut butter topping. It was absolutely delicious, but I was curious to see if it could go from slice to cookie.

The answer was yes. I first attempted to microwave it, but chocolate absorbs too much energy so it burns way too easy. However, it did bake relatively easy.

The best way I've found to do them was to take a piece and place them in the oven after baking something. The residual heat from an electric oven was enough to bake the cookies to be cooked and warmed throughout. Topped with a little ice cream, they were really nice.
