Preheat oven to 350 degrees. In medium bowl, mix flour, cocoa, baking soda and salt; set aside.

In a large bowl, mix together the sugars, butter, shortening, vanilla and eggs with electric mixer at medium speed. Reduce speed to low and add dry ingredients; beat until well combined. Fold in white chocolate chips and nuts by hand.

Drop dough by round tablespoonfuls about 2 inches apart onto ungreased cookie sheets. Bake 10 to 12 minutes, or until set. Cool slightly on the cookie sheet, about 2 minutes, then transfer to wire racks with a spatula to finish cooling.
