Ghiradelli Ultimate Double Chocolate Cookies

In a double boiler over hot water melt the bittersweet chocolate chips and butter. In a large bowl with electric mixer, beat eggs and sugar until thick; stir in chocolate mixture. In a small bowl, stir together flour and baking powder; stir into chocolate mixture. Gently mix in semi-sweet chocolate chips and walnuts.

On a sheet of plastic wrap, form dough into two logs, each 2 inches in diameter and about 8 inches long. Wrap tightly; refrigerate at least 1 hour or until firm. (Dough can also be frozen; thaw in refrigerator before prodeeding with the recipe.)

Preheat oven to 375 degrees. Unwrap dough; with a sharp knife, cut into 3/4-inch slices. Place slices 1 1/2 inches apart on greased or parchment-lined cookie sheets. Bake 12-14 minutes or until a shiny crust forms on top but the interior is still soft. Cool on the baking sheets.
