Step 1

In a medium bowl, mix together the flour, baking soda and salt (I use a whisk), and set aside.

Step 2

Cream the butter and sugars together with a mixer (stand or hand-held). Add the egg, egg yolk, and vanilla and mix well until just combined.

Step 3

Add the flour mixture in batches, mixing to combine in between each batch, until all the flour is incorporated.

Step 4

Stir in the white chocolate chips and macadamia nuts.

Step 5

Cover the bowl with plastic wrap and chill dough for about an hour.

Step 6

Preheat oven to 325 degrees. Roll dough into 1 inch balls and place on a parchment paper lined baking sheet.

Step 7

Press a few more white chocolate chips and macadamia nut pieces onto the tops for extra flavor and presentation. Bake for 8-10 minutes or until edges just ever so slightly browned. The centers of the cookies will look very soft and a little puffy. Let the cookies cool on the baking sheet for a few seconds, then transfer to a wire cooling rack.
