Double Chocolate Chip Cookies

I think this is the last recipe I'm going to try from Alice Medrich's book. I think I need to take a break from baking since I feel my arteries clogging up and my pants fitting a little too tight. I froze some of the dough for later use though!

Alice Medrich

Ingredients:
1 cup all-purpose flour
1/2 unsweetened cocoa powder, dutch process
1/2 tsp baking soda
1/4 tsp baking powder
1/8 tsp salt
8 Tbsp unsalted butter, softened
1/2 cup granulate sugar
1/2 cup packed brown sugar

1 tsp vanilla extract
1/2 cup chopped walnuts
1/2 cup chocolate chips

1. Preheat oven to 350 F. Position the racks in the upper and lower thirds of oven.
2. Combine flour, cocoa, baking soda, baking powder, and salt in a bowl and mix together. Set aside
3. Beat the butter, granulated sugar, and brown sugar with the back of the spoon or with a mixture until smooth and creamy but not fluffy. Mix in the egg and vamilla. Add the flour mixture and mix just until incorporated. Stir in the nuts and chocolate chips.
3. Scoop slightly rounded tablespoons of dough and place about 2 inches apart on cookie sheet. To bake later, form dough into an 11 by 1.75 inch log and wrap in foil. When ready, slice and place on cookie sheet. Bake 12 to 14 minutes, refrigerated dough may need an extra minute. Remove from oven and place on cooling rack immediately.
