Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
In a large bowl, cream together the softened butter, brown sugar, and granulated sugar until light and fluffy, about 3-4 minutes.
Beat in the eggs, one at a time, followed by the vanilla extract, mixing until well incorporated.
In a separate bowl, whisk together the all-purpose flour, baking soda, and salt. Gradually add this dry mixture to the wet ingredients, mixing just until combined.
Gently fold in the white chocolate chips and chopped macadamia nuts until evenly distributed throughout the dough.
Using a tablespoon or a cookie scoop, drop mounds of dough onto the prepared baking sheet, leaving space between each cookie as they will spread.
Bake in the preheated oven for 10–12 minutes or until the edges are golden, and the centers are still soft.
Allow the cookies to cool on the baking sheet for about 5 minutes before transferring them to a wire rack to cool completely.
Notes
For a delightful presentation, serve the cookies in a stack on a decorative plate with a sprinkle of sea salt on top for an added salty-sweet flavor contrast.
