These delicious cookies are rich, decadent and highly addictive. They come together in a flash and you can keep some stashed in your freezer to bake a few whenever you crave something chocolatey.

Makes about 36 cookies
1 1/4 cups all-purpose flour
1/3 cup Dutch-processed cocoa powder
1/2 teaspoon baking soda
1 stick and 3 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 best-quality bittersweet chocolate, chopped into chip-size bits.
1. Sift the flour, cocoa and baking soda together. Put the butter in the bowl of a mixer fitted with a paddle attachment and beat at medium speed until the butter is soft and creamy. Add the sugars, salt and vanilla extract and beat for another 1 or 2 minutes. Reduce the speed to low and add the sifted dry ingredients. Mix only until the dry ingredients are incorporated (the dough may look crumbly). For the best texture, work the dough as little as possible. Toss in the chocolate; mix to incorporate.
2. Turn the dough out onto a smooth work surface, divide in half and, working with one half at a time, shape the dough into a log that is 1 1/2 inches in diameter. (As you’re shaping the log, flatten it once or twice and roll it up from one long side to the other, to make certain you haven’t got an air channel.) Wrap the logs in plastic wrap and chill them for at least 1 hour. (Wrapped airtight, the logs can be refrigerated for up to 3 days or frozen for 1 month.)
3. Center a rack in the oven; preheat oven to 350 degrees. Line 2 baking sheets with parchment paper.
4. Working with a sharp, thin-bladed knife, slice rounds 1/2-inch thick. (If the cookies break, squeeze the broken-off bit back onto the cookie.) Place the cookies on the parchment-lined sheets, leaving an inch of space between them. Bake only 1 sheet at a time and bake each sheet for 12 minutes. (The cookies will not look done nor will they be firm, but that is the way they should be.) Transfer the sheet to a cooling rack and let the cookies rest, on the sheet, until they are only just warm. Repeat with the second sheet of cookies.
Note: It is very important that you not overbake the cookies, and let them cool completely before you remove them from the baking sheet.
