Ingredients

  • 2 1/4 cups all-purpose flour
  • 1 teaspoon baking soda
  • 1 1/4 teaspoons salt
  • 1 cup (2 sticks) unsalted butter, room temperature
  • 1 1/2 cups packed light brown sugar
  • 3/4 cup granulated sugar
  • 2 large eggs
  • 2 teaspoons vanilla extract
  • 12 ounces semisweet chocolate chips or chunks (2 cups)
  • 4 cups heavy cream, well chilled
  • 8 ounces mascarpone cheese
  • 2 tablespoons granulated sugar
  • 1 tablespoon whiskey (optional)
  • Chocolate curls, for garnish

Method

  • To make the cookies: Preheat the oven to 350 degrees F. Line 2 large baking sheets with parchment paper.
  • Sift flour, baking soda, and salt into a bowl.
  • With an electric mixer on medium-high speed, beat the butter and both sugars until pale and fluffy, about 3 minutes.
  • Reduce speed to low.
  • Add eggs, 1 at a time, beating until combined after each and scraping down sides of bowl as needed.
  • Add flour mixture in 3 batches, then beat in vanilla.
  • Fold in chocolate chips.
  • Using a 1 1/4-inch ice-cream scoop (or a tablespoon), scoop dough onto prepared baking sheets, spacing them 2 inches apart.
  • Bake until edges are golden brown and centers are set, 14 to 16 minutes.
  • Transfer sheets to wire racks to cool 5 minutes.
  • Transfer cookies to racks to cool completely.
  • To make the cream: With an electric mixer on medium speed, whisk 3 cups cream and the mascarpone in a chilled bowl until soft peaks form.
  • Add granulated sugar and whiskey (if using).
  • Whisk on medium-high speed until medium-stiff peaks form.
  • Refrigerate until ready to use.
  • To assemble the cake, dab the bottom of 11 cookies with a very small amount of cream mixture; arrange 9 in a circle on a serving plate, with 2 cookies in the middle.
  • Carefully spread 1 cup cream mixture evenly over cookies, leaving a slight border.
  • Repeat to form 7 more layer (staggering cookies), ending with cookies (you'll have a few cookies left over).
  • Refrigerate, lightly draped with plastic wrap, overnight.
  • To serve, whisk remaining 1 cup cream until soft peaks form, and spread over top of cake.
  • Garnish with chocolate curls.
  • To serve, cut the cake into wedges with a serrated knife.
