Equipment

  • 8 Inch Square Baking Pan
  • Parchment paper
  • Light colored saucepan
  • Wooden spoon
  • Wire rack

Ingredients
  

Main Ingredients

  • 9 tbsp unsalted butter about 1 stick plus 1 tbsp
  • 1 cup light brown sugar packed, not dark brown
  • 1 large egg
  • 1 tsp vanilla extract
  • 1 cup all-purpose flour
  • ¼ tsp kosher salt
  • 1 cup white chocolate chips
  • ½ cup walnuts roughly chopped
  • ¼ tsp flaky sea salt for sprinkling

Instructions
 

Cooking

  • Heat and line. Heat the oven to 350 degrees F and line a buttered 8 inch square pan with parchment paper.
  • Toast. Roast the walnuts on a tray for 5 minutes, then set them aside to cool.
  • Brown the butter. Melt the butter in a saucepan over medium-high heat. Lower to medium and simmer 3 to 4 minutes, until golden specks form and it smells nutty. Pour into a bowl.
  • Sweeten. Mix the brown sugar into the hot butter with a wooden spoon and cool for 3 minutes.
  • Mix the batter. Add the egg and vanilla, then the flour and kosher salt, mixing until thick and nearly like cookie dough.
  • Add the extras. Fold in the white chocolate chips and cooled walnuts.
  • Bake. Spread the batter in the pan and bake for 25 minutes, until the edges are lightly golden and the top is crackly.
  • Cool and cut. Rest in the pan for 10 minutes, lift out, cool for 10 more minutes, sprinkle with flaky salt, and cut into 16 squares.

Notes

Substitutions: Use pecans in place of walnuts or dark chocolate chips for white.
Tips: Brown the butter well for flavor and avoid overmixing after the flour goes in.
Storage: Keep in an airtight container at room temperature for up to 4 days, or freeze for up to 3 months.
