From: Smitten Kitchen
Every time I see a Smitten Kitchen cookie recipe that looks good, she references the World Peace Cookies and comments on how well the current cookie recipe compares to the magnificence that is the World Peace Cookie. I wanted to bring a treat to work on Friday to celebrate the end of a very challenging work week. I thought it was time to haul out this recipe, and was happy to see that I already had all the ingredients. Of course, they were delicious, and addictive, and will be made again and again. A few of the commenters complained that the dough was too crumbly (solve this by making sure your butter is at room temperature - it is the only moisture in the cookie so it has to be soft to form a dough), or that their cookies melted into a big pool in the oven (I don't know, that didn't happen to me). I didn't have any problems with these and they came out exactly like they were supposed to.
Makes about 36 cookies
1 1/4 cups (175 grams) all-purpose flour
1/3 cup (30 grams) unsweetened cocoa powder
1/2 teaspoon baking soda
1 stick plus 3 tablespoons (11 tablespoons or 150 grams) unsalted butter, at room temperature
2/3 cup (120 grams) (packed) light brown sugar
1/4 cup (50 grams) sugar
1/2 teaspoon fleur de sel or 1/4 teaspoon fine sea salt
1 teaspoon vanilla extract
5 ounces (150 grams) bittersweet chocolate, chopped into chips, or a generous 3/4 cup store-bought mini chocolate chips
Sift the flour, cocoa and baking soda together.
Working with a stand mixer, preferably fitted with a paddle attachment, or with a hand mixer in a large bowl, beat the butter on medium speed until soft and creamy. Add both sugars, the salt and vanilla extract and beat for 2 minutes more.
Turn off the mixer. Pour in the flour, drape a kitchen towel over the stand mixer to protect yourself and your kitchen from flying flour and pulse the mixer at low speed about 5 times, a second or two each time. 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 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.
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 (I just put it in the freezer for 30 minutes, and it was fine). (The dough can be refrigerated for up to 3 days or 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 the cookies 1 minute longer.)
Getting ready to bake: Center a rack in the oven and preheat the oven to 325°F (160°C). Line two baking sheets with parchment or silicone mats.
Working with a sharp thin knife, slice the logs into rounds that are 1/2 inch thick. (The rounds are likely to crack as you’re cutting them — don’t be concerned, just squeeze the bits back onto each cookie.) Arrange the rounds on the baking sheets, leaving about one inch between them.
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.
Serving: The cookies can be eaten when they are warm or at room temperature — I prefer them at room temperature, when the textural difference between the crumbly cookie and the chocolate bits is greatest — and are best suited to cold milk or hot coffee. (Those were SK's notes, but I agree that they were better at room temp than they were warm).
Do ahead: Packed airtight, cookies will keep at room temperature for up to 3 days (Deb note: not a chance); they can be frozen for up to 2 months. They can also be frozen in log form for months, and can be sliced and baked directly from the freezer, adding a couple minutes to the baking time.
