Lemon Shortbread Trees

Directions

1. In a large bowl, cream the butter, confectioners' sugar and cornstarch until light and fluffy. Beat in lemon zest and juice. Gradually add flour and mix well.
2. Divide dough into two portions; shape each into two 6-in. logs. Flatten top and push in sides at an angle to form a 2x2x1-1/2-in.-triangle. Wrap and chill until firm, for 4 hours.
3. Unwrap and cut into 1/4-in. slices. Place 2 in. apart on ungreased baking sheets. Break pretzel sticks in half; press into short side of each cookie for tree trunk. Bake at 350° 10-12 minutes or until set. Remove to wire racks to cool.
4. In a large bowl, combine the confectioners' sugar, water and meringue powder; beat on low speed just until combined. Beat on high for 4-5 minutes or until stiff peaks form. Remove 1 cup and tint red. Tint remaining icing green. (Keep unused icing covered at all times with a damp cloth.)
5. Frost and decorate cookies as desired. Let dry at room temperature for several hours or until firm. Store in an airtight container.
