Detailed Directions and Instructions
Preheat the Oven
Preheat your oven to 180°C (350°F), or 160°C for fan-forced. Prepare a 20 cm (8″) square baking pan by greasing it with butter and lining the base and sides with baking paper (parchment paper).
Toast the Walnuts
Spread the walnuts on a baking tray in a single layer. Roast them in the preheated oven for 5 minutes. Once done, remove them from the oven and allow them to cool.
Brown the Butter
In a silver saucepan (avoid black), place the unsalted butter over medium-high heat. Once the butter has melted, reduce the heat to medium to let it simmer gently. Let it simmer for 3 to 4 minutes, stirring occasionally. The butter will become foamy and develop a nutty aroma, accompanied by little golden specks. Immediately transfer the browned butter, along with the golden bits, into a mixing bowl.
Mix the Batter
Add the brown sugar into the hot browned butter. Stir with a wooden spoon until the mixture is well combined. Allow it to cool for 3 minutes. Next, add the large egg and vanilla extract, stirring until incorporated. Gradually add the plain/all-purpose flour and kosher salt, mixing until combined. The mixture will be very thick, resembling roll-able cookie dough. Finally, fold in the white chocolate chips and toasted walnuts.
Bake the Mixture
Scrape the batter into the prepared baking pan. Use your hands to spread and smooth the surface evenly. Bake for 25 minutes, or until the edges turn lightly golden and the surface develops a thin, crackly layer.
Cool and Serve
Allow the baked mixture to rest in the pan for 10 minutes before transferring it to a cutting board. Let it cool for at least another 10 minutes to avoid it being too soft. If desired, sprinkle the top with sea salt flakes. Cut the cooled mixture into 16 squares or 9 larger squares. Enjoy!
Notes
Butter
1 US stick (8 tbsp) of butter is approximately 115g; however, using 125g is perfectly fine and more convenient for measurement.
Add-ins
Feel free to customize the add-ins based on your preference, such as using different types of chocolate chips or nuts.
Chocolate Chips
For ease of measurement, one cup of chocolate chips is about 190g, but you can use a standard 200g pack available in Australia.
Toasting Nuts
To enhance flavor and texture, it is recommended to toast the nuts until they smell aromatic, which can also help revive slightly stale nuts.
Storage
Leftovers can be stored in an airtight container for up to 5 days. If the weather is hot, refrigerate them, but always bring them to room temperature before serving.

Cook techniques
Browned Butter
Simmer unsalted butter in a saucepan over medium-high heat until it melts. Reduce heat to medium and continue stirring until it becomes foam-y, fragrant, and develops golden specks, usually 3-4 minutes. This enhances the nutty flavor and adds depth to your recipe.
Toasting Walnuts
Spread walnuts on a baking tray and roast in a preheated oven at 180°C/350°F for about 5 minutes, or until they are fragrant. This step enhances the flavor and improves the texture of the nuts.
Batter Mixing
Combine warm browned butter with brown sugar in a bowl using a wooden spoon. Allow to cool slightly before adding the egg and vanilla extract. Mix until incorporated. Gradually fold in flour and salt until a thick consistency is achieved, similar to cookie dough.
Temperature Control
Ensure your oven is preheated to the correct temperature (180°C/350°F) before baking. This provides even cooking and a desirable texture in baked goods.
Baking Timing
Bake for about 25 minutes or until the edges are lightly golden and a thin, crackly layer forms on the surface. Overbaking can lead to a dry texture, so it’s essential to keep an eye on your dish as it nears completion.
Cooling for Texture
After baking, allow the dish to rest in the pan for 10 minutes before transferring it to a cutting board. Further cooling for at least 10 minutes will help achieve the right texture, making it easier to cut and enhancing overall flavor.
