To prepare a double coco double chocolate chip cookies, you will first need to prepare the ingredients for the cookies. Preheat the oven to 375 degrees F (190 degrees C) and line two baking sheets with parchment paper. Sift the flour, cocoa powder, baking soda and salt into the bowl of the electric mixer and beat until the mixture is light and fluffy, about 2 minutes. Add the chocolate chips and mix until they are evenly coated. Roll the dough into 1-inch balls and place on the parchment-lined baking sheet. Bake for 12 to 15 minutes or until lightly browned. Let cool before transferring to wire racks to cool completely.
