World Peace Cookies

Ingredients

• 1-1/4 cups all-purpose flour
• 1/3 cup unsweetened cocoa powder
• 1/2 teaspoon baking soda
• 1 stick + 3 tablespoons (11 tablespoons) unsalted butter at room temperature
• 2/3 cup (packed) light brown sugar
• 1/4 cup sugar
• 1/2 teaspoon fleur de sel or 1/4 teaspoon fine sea salt
• 1 teaspoon pure vanilla extract
• 5 ounces bittersweet chocolate chopped into bits, or a generous 3/4 cup store-bought mini chocolate chips

Instructions

1. 1
   Sift the flour, cocoa, and baking soda together.
2. 2
   Working with a stand mixer, preferably fitted with a paddle attachmenet, ot with a handy mixer in a large bowl, beat the butter in medium speed until soft and creamy. Add both sugards, the salt and vanilla extract and beat for 2 more minutes.
3. 3
   Turn off the mixer. Pour in the dry ingredients, drape a towel over the stand mixer to protect yourself and your kitchen from the flying flour and pulse the mixer at a low speed about 5 times, a second or two each time.
4. 4
   Take a peek-if there is still a lot of flour on the surface of the dough, pulse a couple of times more.; if not, remove the towel. Continuing at a low speed, mix for about 30 seconds more, just until the flour disappears into the dough-for the best texture, work the dough as little as possible once the flour is added, and don't be concerned if the dough looks a little crumbly. Toss in the chocolate pieces and mix only to incorporate.
5. 5
   Turn the dough out onto a work surface, gather it together and divide it in half. Working with one half at a time, shape the dough into logs that are 1-1/2 inches in diameter. Wrap the logs in plastic wrap and refrigerate them for at least 3 hours. (The dough can be refrigerated for up to 3 days and frozen for up to 2 months. If you've frozen the dough, you needn't defrost it before baking-just slice the logs into cookies and bake for 1 minute longer.
6. 6
   Getting ready to bake: Center a rack in the oven and preheat the oven to 325 degrees F. Line 2 baking sheets with parchment or silicone mats.
7. 7
   Using a sharp thin knife, slice the logs into rounds that are 1/2 inch thick. (The rounds are likely to crack as you are cutting them-don't be concerned, just squeeze the bits back onto each cookie.) Arrange the rounds on the baking sheets, leaving about 1 inch between them.
8. 8
   Bake the cookies one sheet at a time for 12 minutes-they won't look done, nor will they be firm, but that's just the way they should be. Transfer the baking sheet to a cooling rack and let the cookies rest until they are only just warm, at which point you can serve them or let them reach room temperature.
