Small Batch White Chocolate Macadamia Nut Cookies

Preheat the oven to 350°F (177°C). Line a sheet pan with parchment paper and set it aside for later.

Combine the cooled, melted butter, brown sugar, and granulated sugar in a medium mixing bowl. Whisk until the mixture is light and thick, about 1-2 minutes. Then, whisk in the egg yolk and vanilla extract until smooth.

Add the flour, cornstarch, baking soda, and salt. Using a rubber spatula, fold the dry ingredients into the wet ingredients until the dough is about 90% combined. Then, add the white chocolate chips and macadamia nuts and continue folding the dough just until everything is well-mixed and there are no more streaks of flour. Don't over-mix the dough!

Using a #20 cookie scoop (~3 tablespoons), divide the dough into 6 balls. Line the cookie dough balls on the prepared sheet pan about 3 inches apart. Freeze the cookie dough balls for about 15 minutes, or refrigerate for at least 30 minutes, until the dough is well-chilled.

Bake the cookies for 9-11 minutes, flipping the pan halfway through, until the edges are set and the centers are still a bit under-done. Let the cookies cool for 5 minutes on the sheet pan and then transfer them to a wire rack to cool completely. Enjoy!
