2 cups minus 2 tablespoons (8½ ounces) cake flour (approx. 240.97g)
1 & 2/3 cups (8½ ounces) bread flour (approx. 240.97g)
1¼ teaspoons baking soda
1½ teaspoons baking powder
1½ teaspoons kosher salt (I substituted with 1 tsp sea salt)
1¼ cups (10 ounces) unsalted butter, at room temperature
1¼ cups (10 ounces) light brown sugar (approx. 283.50g) (I reduced to 250g)
1 cup plus 2 tablespoons (8 ounces) granulated sugar (approx. 226.80g) (I reduced to 200g)
2 teaspoons vanilla extract
3 & 1/3 cups (20 ounces) dark chocolate chips, at least 60% cacao content (approx 566.99g) (I used 500g)
Sea salt, for sprinkling
1. Sift together the cake flour, bread flour, baking soda, baking powder and salt into a large bowl and set aside.
2. Cream together the butter and sugars on medium speed until very light, about 5 minutes. Add the eggs one at a time, mixing well after each addition, then add the vanilla. Reduce the mixer speed to low, gradually add the dry ingredients and mix until just combined, 5 to 10 seconds. Using a rubber spatula, fold in the chocolate chips.
3. Press plastic wrap against the dough and refrigerate for at least 24 hours, up to 72 hours.
3. When ready to bake, preheat oven to 350 degrees F. Line a baking sheet with parchment paper or a nonstick baking mat. (As I am making smaller sized cookies, I reduced the temp to 140 deg cel)
4. Scoop 3 1/2-ounces of dough, roll into a rough ball (it should be the size of a large golf ball) and place on the baking sheet. Repeat until you have six mounds of dough on the cookie sheet. Sprinkle lightly with sea salt and bake until golden brown but still soft, 18 to 20 minutes. Transfer the parchment or silicone sheet to a wire rack for 10 minutes, then transfer the cookies onto another cooling rack to cool a bit more, until just warm or at room temperature. Repeat with remaining dough (or keep some of the dough refrigerated for up to 3 days, and bake cookies at a later time). Store leftover cookies in an airtight container at room temperature for up to 3 days.
(1) I am not able to find kosher salt (which is coarser and less chemical taste) and so substituted with sea salt. As my sea salt is fine type, I replaced with 1 tsp. If your sea salt is coarse type, you may still use 1 1/2 tsp.
(2) Instead of the size suggested in the above recipe, I made mine smaller, 16g each dough ball. Hence I reduced the temp to 140 deg cel and baked for 12min.
(3) As the dough balls will spread during baking, there is no need to flatten the dough balls before baking.
