Ingredients

  • 1 23 cups all-purpose flour
  • 1 23 cups bread flour
  • 1 14 teaspoons baking soda
  • 1 12 teaspoons baking powder
  • 1 12 teaspoons coarse salt (I used sea salt)
  • 1 14 cups unsalted butter
  • 1 14 cups light brown sugar, packed
  • 1 cup granulated sugar
  • 2 tablespoons granulated sugar
  • 2 large eggs
  • 2 teaspoons vanilla extract
  • 8 ounces milk chocolate, chopped into chunks
  • 4 ounces unsweetened chocolate, grated
  • 8 ounces semi-sweet chocolate chips
  • sea salt

Method

  • Using a mixer fitted with paddle attachment, cream butter and sugars together until very light, about 5 minutes.
  • Add eggs, one at a time, mixing well after each addition.
  • Stir in the vanilla.
  • Reduce speed to low, add dry ingredients (recipe calls for premixing these but I didn't) and mix until just combined, 5 to 10 seconds.
  • Stir all chocolate into dough using a wooden spoon.
  • Press plastic wrap against dough and refrigerate for 24 to 36 hours.
  • Dough may be used in batches, and can be refrigerated for up to 72 hours.
  • When ready to bake, preheat oven to 350 degrees.
  • Line a baking sheet with parchment paper or a nonstick baking mat.
  • Set aside.
  • The original recipe recommends using 3 1/2 ounces of dough per cookie and baking six cookies per baking sheet, but I thought that made for an entirely too large cookie.
  • So I dropped the dough by tablespoonfuls on to the prepared cookie sheet, then sprinkled lightly with sea salt and baked until golden brown, but still soft, 10-12 minutes.
  • Transfer sheet to a wire rack for 3-4 minutes, then slip cookies onto another rack to cool a bit more.
  • Repeat with remaining dough, or reserve dough, refrigerated, for baking remaining batches the next day.
