Heavenly Chocolate Chunk Cookies

I made these cookies for neighbor gifts this year. They are good with a definite coffee taste! I doubled this and it worked well in one bowl but trying to fold in all the walnuts and chocolate chips evenly was a job!
Justin LOVED them. I was trying to get a picture of the inside detail and he climbed onto the table to get a piece.
