Directions

1. In a large bowl, cream butter and confectioners' sugar until light and fluffy. Beat in egg. Combine flour and salt; gradually add to creamed mixture and mix well. Divide dough in thirds. Shape each into a ball, then flatten into a disk. Wrap in plastic and refrigerate for 30 minutes.
2. Preheat oven to 350°. On a lightly floured surface, roll one portion of dough to 1/8-in. thickness. Cut with floured 2-1/2-in. holiday cookie cutters. Using floured 1-in. shaped cookie cutters, cut out the centers of half of the cookies.
3. Place solid and window cookies 1 in. apart on greased baking sheets. Repeat with remaining portions of dough. Bake 8-10 minutes or until set. Remove to wire racks to cool completely.
4. Sprinkle window cookies with additional confectioners' sugar. Spread 1 teaspoon Nutella on the bottom of each solid cookie; place window cookies over filling.
