White Chocolate Macadamia Nut Cookies

Preheat oven to 375 degrees F. Melt butter and allow to cool. In a stand mixer fitted with the paddle attachment, mix together butter and both sugars until smooth. Add the egg, yolk, and vanilla until well combined. Be sure to stop and scrape the sides often so that all ingredients are mixed well. Gradually add the dry ingredients until the mixture is completely mixed and smooth. Remove bowl from mixer, and by hand, stir in the white chocolate chips and macadamia nuts until they are distributed throughout the entire dough. Refrigerate for 30 minutes. Scoop the dough onto the cookie sheet with a cookie or ice cream scoop and bake until ALMOST done. Remove from oven and allow to rest on the cookie sheet for 3-4 minutes, then remove to a cooling rack. Serve warm or room temperature.
