We made these once before. They're tasty - a layer of shortbread topped with chocolate topped with crushed peppermint candies and drizzled with white chocolate. They're also simple: a basic dough is pressed into a 13 x 9 pan and baked. The chopped chocolate is placed on top as soon as the dough is done baking. It melts and you spread it around to cover the shortbread then immediately sprinkle on the crushed peppermint candies. We microwaved the white chocolate to melt it and drizzled it on top.
The only problem now is that I cannot decided if I like these or the Chocolate Peppermint Pinwheels better for a chocolate-peppermint cookie. Fortunately, both freeze well.
