The BEST Chocolate Chip Cookies Ever!!!

Chocolate Chip Cookies 

- 2 cups minus 2 tablespoons (8 1/2 ounces) cake flour
- 1 2/3 cups (8 1/2 ounces) bread flour 
- 1 1/4 teaspoons baking soda 
- 1 1/2 teaspoons baking powder 
- 1 1/2 teaspoons coarse salt 
- 2 1/2 sticks (1 1/4 cups) unsalted butter (note: If I only have salted butter on hand, I use 1 teaspoon regular salt instead of 1 1/2 tsp. coarse salt) 
- 1 1/4 cups (10 ounces) light brown sugar 
- 1 cup plus 2 tablespoons (8 ounces) 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 (note: you can use regular semi-sweet chocolate chips here, but if you can find disc shaped chips, it is pretty awesome…you end up with layers of chocolate in the cookies, which is heaven.) 
- Sea salt 

1. Sift both flours, baking soda, baking powder and salt into a bowl. Set aside. 

2. 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. Dough may be used in batches, and can be refrigerated for up to 72 hours. (note: I usually make the dough balls and THEN refrigerate the dough in a ziploc bag. I think the dough should ideally be refrigerated at least a day the texture comes out better, but if you really can't wait and cook a few cookies when you make the dough, they'll be good, just not best.) 

3. When ready to bake, preheat oven to 350 degrees. Line a baking sheet with parchment paper or a nonstick baking mat. Set aside. 

4. 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. (If you do smaller cookies, adjust cooking time accordingly.) Transfer sheet to a wire rack for 10 minutes, then slip cookies onto another rack to cool a bit more. 

Yield: 1 1/2 dozen 5-inch cookies
