Glazed Maple Shortbread Cookies Recipe

In a large bowl, beat butter, sugar and cornstarch until blended. Beat in flavoring. Gradually beat in flour. Shape dough into a disk; wrap in plastic wrap. Refrigerate 45 minutes or until firm enough to roll. Preheat oven to 325 °. On a lightly floured surface, roll dough to 1/4-in. thickness. Cut with a floured 2-3/4-in. leaf-shaped cookie cutter. Place 1 in. apart on parchment paper-lined baking sheets. Bake 20-25 minutes or until edges are light brown. Remove from pans to wire racks to cool completely. In a small bowl, mix confectioners' sugar and maple syrup until smooth. Spread over cookies. Let stand until set.
