2 cups minus 2 tablespoons cake flour
1 2/3 cups bread flour
1 1/4 teaspoons baking soda
1 1/2 teaspoons baking powder
1 1/2 teaspoons coarse salt
2 1/2 sticks unsalted butter
1 1/4 cups light brown sugar
1 cup plus 2 tablespoons granulated sugar
2 large eggs
2 teaspoons natural vanilla extract
1 1/4 pounds bittersweet chocolate disks or fèves, at least 60 percent cacao content
- Sift flours, baking soda, baking powder and salt into a bowl.
- Set aside.
- 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 and mix until just combined, 5 to 10 seconds.
- Drop chocolate pieces in and incorporate them without breaking them.
- Press plastic wrap against dough and refrigerate for 24 to 36 hours.
- When ready to bake, preheat oven to 350 degrees.
- Line a baking sheet with parchment paper or a nonstick baking mat.
- Scoop 6 3 1/2-ounce mounds of dough (the size of generous golf balls) onto baking sheet, making sure to turn horizontally any chocolate pieces that are poking up; it will make for a more attractive cookie.
- Sprinkle lightly with sea salt and bake until golden brown but still soft, 18 to 20 minutes.
- Transfer sheet to a wire rack for 10 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.
Yield: 1 1/2 dozen 5-inch cookies.
