Ingredients:
- 1 cup (227g) Unsalted Butter
- 1 ¼ cups (250g) Light Brown Sugar, packed
- ½ cup (100g) Granulated Sugar
- 3 Large Eggs
- 2 teaspoons Pure Vanilla Extract
- 1 cup (125g) All-Purpose Flour
- ½ teaspoon Fine Sea Salt
- ½ teaspoon Baking Powder
- 1 ½ cups (255g) White Chocolate Chips, divided
- 1 cup Toasted Pecans or Macadamia Nuts (optional)
Instructions:
- Preheat oven to 350°F (175°C). Line an 8x8 inch metal baking pan with parchment paper, ensuring there is an overhang on two sides.
- Melt the butter gently in a saucepan over medium heat. Continue cooking, stirring frequently, until the milk solids toast and turn golden brown, releasing a nutty aroma. Immediately pour the browned butter into a large heatproof bowl to stop the cooking process.
- Add both the brown and granulated sugars to the warm browned butter. Whisk vigorously until the mixture is thoroughly combined and slightly glossy.
- Add the eggs one at a time, whisking well after each addition until the mixture looks cohesive. Stir in the vanilla extract.
- In a separate small bowl, whisk together the flour, salt, and baking powder.
- Gently fold the dry ingredients into the wet mixture using a rubber spatula until just combined. Do not overmix.
- Fold in 1 cup of the white chocolate chips and any optional nuts. Reserve the remaining ½ cup of chips for topping.
- Spread the batter evenly into the prepared pan. Sprinkle the reserved white chocolate chips over the top.
- Bake for 30–35 minutes. The edges should look set, and a toothpick inserted near the centre should come out with moist, fudgy crumbs attached.
- Let the white brownies cool completely in the pan on a wire rack (at least 2 hours) before using the parchment sling to lift them out and cut into 16 neat squares.
