I’m sure there are a million chocolate chip recipes out there, but this one seems to be very well considered and makes fabulous, complex chocolate chip cookies. 
2 cups minus 2 tablespoons cake flour (8 1/2 ounces)
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 white granulated sugar
2 large eggs
2 teaspoons natural vanilla extract
1 pound bittersweet chocolate disks, at least 60% cocao (see below) Cut into halves or quarters.
Malden sea salt
Directions:
Sift flours, baking soda, baking powder and salt in a bowl. Set aside.
In a stand mixer with a paddle attachment, cream the butter and sugars together until very light. The original recipe said this would take 5 minutes but I did it on a summer day and it only took about 2 minutes. Add eggs (room temp) one at a time, mixing well. Add vanilla.
Reduce speed to low, add dry ingredients and mix until combined. The original recipe said this would take about 5-10 seconds but it took about a minute. Drop in the chocolate discs and incorporate without breaking. (These discs are huge, the next time I’m going to cut them in half. Also, you can buy them in a four pound bag and using a pound an a quarter isn’t necessary. A pound would be fine and you’d get four batches per bag of chips.)
Cover with plastic wrap, pushing it down onto the dough with no air space. I put a second sheet of plastic wrap over the bowl as well. Refrigerate for at least 24 hours, 36 is better, my first batch actually went 48 hours. Up to 72 hours is supposed to be OK.
Preheat to 350 degrees. Line a baking sheet with either parchment paper or a silpat mat.
Make 2 ounce scoops of dough, which is slightly bigger than a golf ball, sprinkle with sea salt. Bake for seven minutes, spin the sheet 180 degrees, bake for six minutes more. Once out of the oven, let sit on baking sheet for ten minutes more, then transfer to a wire rack.
Yield: about 30 cookies.
