Preheat oven to 350 degrees F (175 degrees C).

In large bowl, beat butter, sugar, eggs, and vanilla until light and fluffy.Combine the flour, cocoa, baking soda, and salt;Stir into the butter mixture until well blended. Mix in the chocolate chips and walnuts.Drop by rounded tablespoonfuls onto parchment lined cookie sheets. I usually roll the dough in my hands to form a ball. Place some nuts or chocolate chips on top of the rounded cookie dough, slightly pushing them in the dough. This way they won't fall off when baked. Refrigerate cookies for 15-20 minutes, while you clean up and preheat the oven. Bake for 8 to 10 minutes in the preheated oven, or just until set.Cool slightly on the cookie sheets before transferring to wire racks to cool completely.

If you don't want to use the whole amount of sugar, use 1/2 cup instead of 3/4cup. They are great!

Double the recipe if you want to make more cookies.

You can omit the orange flavor, if you like.

TIP:You can also freeze the cookie dough. Just make cookie balls, freeze till hardened, and place in a freezer bag. This way you have ready-made cookie dough at your fingertips....ready to be baked, any time of the day:)
