Dough for these cookies is rolled into a thick log and refrigerated until very firm. It's cut into ten thick slices and baked up with a gooey marshmallowy topping. When I baked my test cookies, the marshmallow topping browned up
waaaaaayyyy too much, so I modified D'Lish's recipe to include baking the cookie until it spreads a bit, and
then adding the marshmallow topping. That worked much better.
I would have liked them to be a little prettier. They're kind of an ugly cookie, dontcha think? But don't let that uglyness fool you. These cookies are really great. Toffee bits are melted within the giant chocolate goodness, and then you get gooey marshmallow in every bite too. The recipe makes 10 giant cookies, exactly.
