Preheat the Oven:

Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper.

Cream the Butter and Sugars:

In a large mixing bowl, beat the softened butter, granulated sugar, and brown sugar with an electric mixer until light and fluffy.

Add the Eggs and Vanilla:

Beat in the eggs one at a time, then add the vanilla extract. Mix until well combined.

Combine Dry Ingredients:

In a separate bowl, whisk together the flour, baking soda, and salt. Gradually add the dry ingredients to the wet mixture, mixing until just combined.

Fold in the Mix-Ins:

Stir in the white chocolate chips and chopped macadamia nuts until evenly distributed.

Scoop and Bake:

Drop rounded tablespoons of dough onto the prepared baking sheet, spacing them about 2 inches apart. Bake in the preheated oven for 10-12 minutes, or until the edges are lightly golden. The centers may still look slightly soft, but they will firm up as the cookies cool.
