Instructions

1. Preheat the oven to 350°F (175°C). Line an 8x8 inch baking pan with parchment paper, allowing excess paper to hang over the sides for easy removal.
2. In a medium saucepan, melt the unsalted butter over low heat. Remove from heat and whisk in the brown sugar until fully combined and smooth.
3. Add eggs one at a time to the butter-sugar mixture, beating well after each addition. Stir in the vanilla extract until the mixture is glossy and well incorporated.
4. In a separate bowl, sift together the all-purpose flour and salt to remove any lumps and ensure even distribution.
5. Gently fold the dry ingredients into the wet mixture, stirring just until combined. Be careful not to overmix, which can result in tough brownies.
6. Fold in the white chocolate chips and chopped macadamia nuts, distributing them evenly throughout the batter.
7. Pour the batter into the prepared baking pan, spreading it evenly with a spatula and ensuring the nuts and chocolate chips are well distributed.
8. Bake in the preheated oven for 22-25 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs.
9. Remove from the oven and let cool in the pan for 10 minutes, then use the parchment paper to lift the brownies out and transfer to a wire rack to cool completely.
10. Once cooled, cut into 12 equal squares. For clean cuts, use a sharp knife and wipe it clean between each slice.
