In a large mixing bowl, cream together the butter, granulated sugar, brown sugar, and vanilla until it's light and fluffy.
Add egg and beat well.
In a separate bowl, combine the flour, baking soda, and salt. Gradually add this flour mixture into the butter mixture, beating well.
Stir in the chocolate chips and macadamia nuts.
Refrigerate the dough for at least one hour. This will harden-up the butter up again so that the cookies bake evenly.
Preheat the oven to 350° Fahrenheit.
Use a medium cookie scoop (or a rounded tablespoon) to drop the cookie dough onto a parchment paper lined cookie sheet.
Slightly flatten the cookie dough balls with the palm of your hand so they are in a disc shape.
Bake 11-13 minutes or until they are golden brown. Cool slightly before moving from cookie sheet to a wire rack for cooling.
