Chocolate Crinkle Cookies - cooking recipe

Ingredients

1 cup all-purpose flour
1/2 cup unsweetened cocoa powder
1 teaspoon baking powder
1/4 teaspoon baking soda
1/2 teaspoon salt
1 1/2 cups packed brown sugar (10 1/2 ounces)
3 large eggs
4 teaspoons instant espresso powder (optional)
1 teaspoon vanilla extract
4 ounces unsweetened chocolate, chopped
4 tablespoons unsalted butter
1/2 cup granulated sugar
1/2 cup confectioners' sugar

Preparation

Adjust oven rack to middle position and heat oven to 325°F Line two baking sheets with parchment paper. Whisk flour, cocoa, baking powder, baking soda and salt together in bowl.
Whisk brown sugar; eggs; espresso powder, if using; add vanilla together in large bowl. Microwave chocolate and butter in bowl at 50 percent power, stirring occasionally, just until melted, 2 to 3 minutes (watch carefully).
Whisk chocolate mixture into egg mixture until combined. Fold in flour mixture until no dry streaks remain. Let dough sit at room temperature for 10 minutes.
Spread granulated sugar in shallow dish. Spread confectioners' sugar in second shallow dish. Working in batches, drop 2-tablespoon mounds of dough (or use #30 scoop) directly into granulated sugar and roll to coat. Transfer dough balls to confectioners' sugar and roll to coat; space dough balls evenly on prepared sheets, 11 per sheet.
Bake cookies, 1 sheet at a time, until they are puffed and cracked and edges have begun to set but centers are still soft (cookies will look raw between cracks and seem underdone), about 12 minutes, rotating sheet halfway through baking. Let cookies cool on sheet for 5 minutes, then transfer to wire rack. Let cookies cool completely before serving.
