Detailed Directions and Instructions
Step 1: Preheat the oven
Preheat the oven to 180°C (350°F) or 160°C (320°F) for a fan-forced oven. Grease a 20 cm (8-inch) square pan with unsalted butter, then line it with parchment paper to prevent sticking.
Step 2: Toast the walnuts
Spread the chopped walnuts evenly on a tray and toast them in the preheated oven for 5 minutes. Once toasted, remove them from the oven and allow them to cool.
Step 3: Brown the butter
In a light-colored saucepan, place the unsalted butter over medium-high heat. Once the butter has melted, reduce the heat to medium and let it simmer gently. Stir occasionally for 3 to 4 minutes until the butter gives off a nutty aroma and small golden specks appear. Transfer the browned butter along with the golden bits into a mixing bowl immediately.
Step 4: Combine butter and sugar
Add the brown sugar to the hot browned butter, mixing well with a wooden spoon. Allow the mixture to cool for 3 minutes.
Step 5: Incorporate egg and vanilla
Once the butter-sugar mixture has cooled slightly, add the egg and vanilla extract. Stir well until fully combined.
Step 6: Add flour and salt
Sift in the all-purpose flour along with the kosher salt (or half the amount if using table salt). Stir until all the ingredients are thoroughly incorporated. The batter will be thick, similar to cookie dough.
Step 7: Mix in chocolate and walnuts
Gently fold in the white chocolate chips and the toasted walnuts, ensuring they are evenly distributed throughout the batter.
Step 8: Prepare for baking
Transfer the batter into the prepared square pan, spreading and smoothing the top with a spatula or your hands to create an even surface.
Step 9: Bake the blondies
Place the pan in the oven and bake for 25 minutes, or until the edges are lightly golden and the surface has formed a thin, crackly layer.
Step 10: Cool the blondies
Once baked, let the blondies rest in the pan for 10 minutes. Afterward, transfer them to a cutting board to cool for at least another 10 minutes. Optionally, sprinkle the top with sea salt flakes.
Step 11: Cut and enjoy
Cut the cooled blondies into 16 smaller squares or 9 larger squares as desired, and enjoy your delicious treat!
Notes
Note 1: Brown sugar
Using light brown sugar is recommended for a milder flavor, while dark brown sugar can result in a richer taste.
Note 2: Egg size
Ensure that the large egg used is approximately 50g (2 oz) for accurate measurements.
Note 3: Storage
Store any leftovers in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate for up to a week.
Note 4: Customization
Feel free to substitute walnuts with other nuts, or omit them completely if preferred. Additional mix-ins like dried fruit or coconut can also be used.

Cook techniques
Browning Butter
Browning butter involves melting it and allowing it to cook until it turns a golden color and has a nutty aroma. This process enhances the flavor of the butter and adds depth to baked goods.
Toasting Nuts
Toasting walnuts in the oven helps to intensify their flavor and crunchiness. Spread them evenly on a tray and bake for a few minutes, keeping an eye on them to prevent burning.
Combining Wet and Dry Ingredients
When mixing wet ingredients like melted butter, sugar, eggs, and vanilla with dry ingredients such as flour and salt, it’s important to do this gently to minimize gluten development and maintain a tender texture.
Folding in Ingredients
Gently folding in chocolate chips and walnuts into the batter ensures they are evenly distributed without overmixing, which can lead to a tough texture.
Proper Cooling
Allowing the blondies to cool in the pan and then on a cutting board helps to set their structure and enhances flavor. The resting time also allows for easier cutting.
