Coffee Chocolate Chunk Cookies

Preheat the oven to 375 degrees F. Place the racks in the center of the oven.
In a mixing bowl, make a well in the center of the chocolate chip cookie mix. Add the chocolate chunks, walnuts, softened butter, Kahlua, instant espresso, ground coffee and egg. Mix well to combine all the ingredients into the cookie dough. Scoop with a small scoop or by heaping tablespoons and drop the dough 2 inches apart on ungreased, nonstick cookie sheets or sheets lined with parchment paper. Chill for 5 to 10 minutes.
Bake the cookies in batches, until set and lightly browned but not crisp, 9 to 11 minutes. Remove from the oven and leave on the cookie sheets for about 5 minutes before transferring to a wire rack to cool before serving.
