This is a recipe for an amazingly dense and rich yet delicate cookie. You can't eat just one. When I make them, they're gone in a sitting and guests, family members and friends love and look forward to these. I can easily eat 10 in a row. The delicate nature is due to the cornstarch which most recipes I've come across do not include. They taste great with coffee and hot cocoa. This recipe comes from the back of an old box of Benson's Cornstarch. I kept the empty box for years in the hopes of making them one day. I always double the recipe to make about 50 small cookies.
