1 cup granulated sugar, divided
1 cup chopped walnuts
1 tsp. flaky salt, divided, plus more for garnish
½ cup (4 oz.) unsalted butter, cut into ½-in. cubes, cold but slightly softened
½ cup packed light brown sugar
1 large egg, at room temperature
1 tsp. vanilla extract
¾ tsp. baking soda
½ tsp. baking powder
1⅔ cups (about 7⅛ oz.) all-purpose flour
1/2 cup (4 oz) unsalted butter, cut into 1/2 inch cubes, cold but slightly softened.
8 oz. semi- or bittersweet chocolate chips (about 1⅓ cups)
1.
Preheat oven to 350°. Line 3 baking sheets with parchment paper. Pour ⅔
cup granulated sugar into a 10-inch skillet; cook, undisturbed, over
medium-high heat until sugar is partially liquefied, 3 to 4 minutes.
Whisk until sugar is completely melted; cook, whisking constantly, until
sugar is copper-colored and slightly smoking, 30 seconds to 1 minute.
Remove from heat; quickly stir in walnuts.
2.
Scrape brittle onto 1 baking sheet; quickly spread as thin as possible
using a spatula. Sprinkle with ¼ teaspoon flaky salt. Chill in freezer
until solid, 10 to 15 minutes.
3.
Beat together butter, brown sugar, ⅓ cup granulated sugar and ¾
teaspoon flaky salt with a stand mixer fitted with the paddle attachment
on low speed just until combined, about 2 minutes. Increase speed to
medium; beat until butter is softened and somewhat fluffy, 3 to 4
minutes, stopping to scrape down sides as needed. Add egg and vanilla;
beat until combined, about 30 seconds.
4.
Add baking soda and baking powder; beat until combined, about 10
seconds. Add flour; beat on low speed just until a few floury patches
remain, about 30 seconds.
5.
Smash chilled brittle into bite-size chunks. Add brittle and chocolate
to dough; beat on low speed just until incorporated, about 10 seconds.
Scoop dough into 3-tablespoon-size balls, spaced 2 inches apart on the 2
baking sheets.
6.
Bake in oven, one pan at a time, until edges are golden brown and set
but centers are soft, 10 to 14 minutes. Cool on pan on a wire rack, 5
minutes; garnish with flaky salt. Serve warm.

Quick tip!
"While you can bake it right away, the dough will keep for several days
in the fridge," says Perelman. The brittle can be frozen for up to
three months.
