Blonde chocolate is essentially caramelized white chocolate; though it's not quite the same, white chocolate can be substituted.
16 tablespoons unsalted butter, plus more for pan
1 cup (8 ounces) packed dark brown sugar
1/2 cup (3 1/2 ounces) granulated sugar
2 large eggs
1 1/2 teaspoons pure vanilla extract
2 cups (10 ounces) all-purpose flour
1 1/2 teaspoons kosher salt
About 3/4 cup (4 ounces) Valhrona blonde chocolate 
About 1/2 cup (2 1/2 ounces) chopped pecans
- Preheat oven to 350°F. Grease an 8-inch square baking pan with butter; line pan with parchment paper, leaving a 2-inch overhang on two sides.
- Brown the butter  over medium heat. Once browned, take off the heat and add one ice cube, whisking to combine.
- In a large bowl, whisk together the brown butter and sugars until smooth. Whisk in eggs and vanilla. Add flour and salt; stir just until moistened. Fold in the blonde chocolate and pecans.
- Transfer batter to prepared pan, and smooth top.
- Bake until top of blondies are golden brown and a toothpick inserted in the center comes out clean, 45 to 50 minutes. Set pan on a wire rack, and let cool completely. Using parchment overhang, lift cake from pan and transfer to a cutting board; cut into 16 squares. To store, keep in an airtight container at room temperature, up to 2 days.
