In a small bowl, whisk together the flour, salt and the baking soda and keep it ready.

In a large bowl, add the softened butter along with both the sugars. Using a hand mixer, beat it well until well incorporated. You could use a stand mixer as well but the hand mixer worked well for me.

Add the egg and the vanilla extract and beat it until creamy and smooth (about 3 to 4 minutes).

Slowly add the flour mixture to the bowl and run the mixer through just until the flour has incorporated.

Add the chocolate chip cookies and the macadamia nuts to the dough and mix to combine.

Preheat the oven to 350 F and layer a baking sheet with parchment.

Measure a little more than a tablespoon of cookie dough and roll it into a ball.

Place the dough balls in the prepared baking sheet about 2 inches spaced. The cookies will spread when baking, so space them well.

Bake for about 10 to 12 minutes or until the cookies are pale brown. Remove the pan from the oven and leave it on the pan for 2 more minutes. The cookies will be quite soft when they come out and will firm up a bit in the pan.

Transfer the cookies to a cooling rack to cool them and enjoy!
