238gramsall-purpose flour or bread flour (both work)(1 ½ cups plus 3 tablespoons)
½tspbaking soda
½tspsalt (Morton Kosher)3 grams (1 teaspoon for Diamond)
168gramsunsalted butter, softened(12 tablespoons)
134grams dark brown sugar, lightly packed(½ cup plus 2 tablespoons)
104gramsgranulated sugar(½ cup plus 1 teaspoon)
12gramsunsulfured blackstrap molasses1 ¾ teaspoon
60gramsof beaten egg1 jumbo
107gramschocolate chunks or disks(⅔ cup)
107gramsbittersweet chocolate chips(⅔ cup)
Instructions
In a medium bowl, stir or whisk together the flour, baking soda, and salt. Set aside.
In a stand mixer fitted with the paddle attachment, beat butter on medium speed until creamy. Add both sugars and molasses and cream until light and fluffy, scraping the bowl as needed.
Using lowest speed of mixer or just stirring by hand, stir in the egg until it is blended.
Scrape the bowl and add the flour mixture in two parts, mixing until just combined. Scrape the bowl once more to ensure that all of the flour is incorporated from the bottom. Don't add the chocolate quite yet.
Empty the dough onto a sheet of wax or parchment paper and press down into a slab about ¼ inch thick. Lay chocolate disks (or whatever type chocolate you are using) across half of the slab, then fold the other half of the dough over the chocolate. Press down again and repeat, layering half of the slab with chocolate and folding over. Do this one more time or until you've incorporated all of the chocolate evenly. Cut into 6 portions and press into rounds.
Put the rounds in the refrigerator, cover and chill overnight or until ready to bake. Or bake right away!
Preheat oven to 325 degrees.
Arrange cookie dough disks on parchment lined baking sheet leaving plenty of room for them to spread (at least 4 inches). Bake for 15 to 20 minutes at 325 or until cookies are set. If they are very cold, they may take up to 23 minutes. You can check earlier or later. I don't like underbaked cookies so I tend to bake longer.
Let the cookies cool directly on the baking sheet for about 10 minutes (or on a brown paper sack), then transfer to a wire rack.
