Empty pound cake mix into a large bowl. Add the egg, melted butter and walnuts and mix until well-blended. With clean hands, shape dough into 1-inch balls and place on greased cookie sheets. Bake for 15 minutes ( tops will be cracked a bit, like brownies). Don't over bake.
Remove from oven and cool for a few minutes then remove with a spatula and place on wire racks to cool completely. Makes about 36 cookies.
