It’s all hands on deck for this monster of a cookie! We spread the dough out onto one baking dish to create a giant rectangular communal treat. It comes out of the oven like a canvas ready to be decorated with roasted pecans, roughly chopped chocolate and a gooey caramel (or any other toppings you like). The baking dish conveniently packs flat, and just needs to be deep enough that the cookie doesn’t crisp up before it’s cut. What’s more kid-friendly, or travel-friendly, than that?
