Ingredients
4 cups all-purpose flour
1 1/2 teaspoons baking soda
1 1/2 teaspoons salt
6 tablespoons unsalted butter, softened
1 1/2 cups packed light-brown sugar
3/4 cup granulated sugar
3 teaspoons pure vanilla extract
2 large eggs, plus 2 egg yolks
3/4 cup heavy cream
3 cups semisweet chocolate chips
40 ounces (5 packages) cream cheese, room temperature
1/2 cup confectioners' sugar
Cooking Directions
1. Preheat oven to 350°.Whisk flour, baking soda, and salt in a medium bowl. Put butter and brown and granulated sugars into mixer bowl; mix on medium until pale and fluffy. Mix in vanilla, eggs, and yolks. Reduce speed to low. Add flour mixture in 2 batches, alternating with the cream. Stir in chocolate chips.
2. For each of the 5 layers, drop 1 level cup batter onto center of a baking sheet lined with parchment (keep unbaked dough refrigerated). Using a small offset spatula, spread into an 8-inch circle. Bake until edges are pale golden brown, about 12 minutes. Remove from oven. Use offset spatula to reshape circle. Return to oven; bake until edges are golden brown, 8 to 10 minutes more. Transfer to wire rack; let cool. Can be stored airtight up to 1 day.
3. Mix cream cheese and confectioners' sugar in clean mixer bowl on medium-high speed until pale and fluffy. Spread onto 4 cookies. Stack cookies, placing unfrosted cookie on top. Refrigerate until frosting is set, at least 20 minutes or up to 4 hours. Serve at room temperature.
