Preheat oven to 375ºF. Sift together flour, baking soda and salt; set aside. In large mixer bowl, cream together butter, sugar, brown sugar, cream cheese, and vanilla. Gradually blend dry mixture into butter/sugar mixture. Stir in chocolate chips. Drop heaping tablespoons (I use a 18/8 cookie scoop) onto ungreased cookie sheets about 2 inches apart. Bake at 375ºF for 9 to 11 minutes, or until golden brown.
