1¼ cups all-purpose flour
3 tablespoons + 1 teaspoon unsweetened cocoa powder
½ teaspoon baking powder
½ teaspoon salt
20 ounces bittersweet chocolate, finely chopped
10 tablespoons unsalted butter, at room temperature
2¼ cups granulated sugar
6 eggs, at room temperature
1 tablespoon vanilla extract
2 cups semisweet (or bittersweet) chocolate chips
1. Preheat oven to 350 degrees F. Line 2 or 3 baking sheets with parchment paper; set aside.
2. In a medium bowl, sift together the flour, cocoa powder and baking powder. Whisk in the salt and set aside.
3. Melt the chocolate by microwaving on 50% power, stirring every 30 seconds, until completely melted and smooth. Allow the chocolate to cool for 10 minutes.
4. Meanwhile, combine the butter and sugar in the bowl of an electric mixer and cream on medium speed until pale and fluffy, about 3 minutes. Add the eggs, one at a time, mixing well after each addition. Increase the speed to high and beat for 3 minutes, until the mixture is very light, creamy, and pale in color, scraping the bowl down as needed (the mixture will resemble a custard). Reduce the mixer speed to low and add the melted chocolate and vanilla extract, mixing just until combined. Use a rubber spatula to fold in the dry ingredients, then fold in the chocolate chips.
5. Scoop the cookies into 1½-ounce mounds (or a scant ¼ cup) about 2 inches apart on the prepared baking sheets. Flatten each mound of dough slightly with your hand (if the dough is still sticky dampen your hand to make it easier).
6. Bake the cookies until they are evenly cracked all over the tops and softly set, 14 to 16 minutes, rotating the pan halfway through the baking time.
7. Allow the cookies to cool completely before removing them from the baking sheets with a metal spatula. The cookies can be stored in an airtight container at room temperature for up to 5 days.
- Start scooping the cookies as soon as you finish making the batter. The batter is very soft at first, but it starts firming up quickly as it sits, which will make it more difficult to scoop.
- This dough should not be chilled, as the cookies will not spread properly if the dough is chilled. The cookies should be baked immediately after the dough is mixed and scooped. Source Brown Eye Baker
