Directions:In a medium saucepan, melt together unsalted butter and semisweet chocolate (bars). Stir frequently over medium heat until smooth. Let cool for 15 minutes. In a medium bowl, whisk together flour, unsweetened cocoa powder, baking powder and salt. Using an electric mixer, beat together light brown sugar, 3 eggs and pure vanilla extract. Beat on low speed until smooth, 2 minutes. Mix in the cooled chocolate mixture just until blended. Add the flour mixture in 2 batches, mixing on low speed until just combined. Refrigerate the dough for at least 1 hour. Preheat the oven to 325 degrees. Line 2 large baking sheets with parchment paper. Using a tablespoon, scoop the dough and roll between your palms to form 1-inch balls. Arrange about 16 balls 2 inches apart on each cookie sheet, flattening slightly. Bake until the tops of the cookies crack, about 12 minutes. Meanwhile, cut 7.5 ounces of semisweet chocolate (bars) into 1-inch squares. Snip 8 marshmallows in half crosswise and stick 1 square of chocolate onto each of the cut sides.
Remove the cookie sheets from the oven and gently press a marshmallow half, chocolate side down, into each cookie. Bake until the marshmallows are just softened, about 4 minutes. Transfer the pans to racks to cool for 5 minutes. Grate 5 ounces of semisweet chocolate over the hot cookies. Using a spatula, transfer the cookies to the racks and let cool. Repeat the process with the remaining dough, marshmallows and chocolate. Bake each batch on a clean sheet of parchment paper. |
