Line your cookie sheets with parchment paper or a silicone mat.
Mix the flour, baking soda, and salt in a bowl.
Set this mixture aside.
In a separate bowl, cream together the butter, brown sugar, and sugar until light and fluffy.
Add the vanilla and the egg, and mix until well combined.
Gradually blend in the flour mixture.
Stir in the macadamia nuts and white chocolate chips to combine evenly.
Scoop dough onto the prepared cookie sheets, spacing them evenly.
Bake for 10-12 minutes or until golden brown.
