Delicious cookies that are incredibly chewy and rich.
Place the butter in a small saucepan and melt over the lowest possible heat. Add 8 ounces of the chopped chocolate and melt together, stirring frequently. Continue until the mixture is melted and warm, but not hot. Add the cocoa powder to the chocolate and whisk until combined. Turn off the heat and keep warm.
You can enjoy these warm or at room temperature. The cookies are best the day you bake them, but will keep for up to 3 days in an airtight container
