CHOCOLATE SAMBUCA CRINKLE COOKIES

Steps:

• Sift together flour, baking powder, and salt. Melt chocolate with butter in a metal bowl set over a saucepan of simmering water, stirring until smooth. Lightly whisk together eggs, walnuts, Sambuca, and granulated sugar in another bowl. Stir in flour mixture and chocolate (dough will be thin). Chill, covered, until firm, about 2 hours.
• Preheat oven to 350°F.
• Sift confectioners sugar onto a plate. Roll heaping tablespoons of dough into balls and roll balls, as formed, in confectioners sugar to generously coat. Arrange balls 2 inches apart on 2 lightly buttered baking sheets and bake in upper and lower thirds of oven, switching position of sheets halfway through baking, until puffed and cracked but centers are still a bit soft, 10 to 12 minutes total. Transfer to racks to cool.
