In a bowl, whisk the softened butter with the granulated and brown sugar and mix until you obtain a fluffy mixture.
Add the egg and vanilla extract and whisk again to combine.
Add the dry ingredients, flour, baking soda and sea salt and mix with a spatula or wooden spoon just until combined.
Add the cranberries, macadamia nuts and white chocolate chips, film and place in the chill for 30 minutes to 2 hours.
Preheat your oven to 350°F / 180 °C and line a baking tray with parchment paper.
Using a large tablespoon or, ideally, an ice cream scoop, scoop out balls of dough weighing approx. 40-50 g, place them on the baking tray at sufficient intervals as they will spread and swell.
Bake for about 12-15 minutes, when they start to have a nice golden brown color, take them out of the oven and let them cool a little before moving them and then let them cool completely on a wire rack
