Stacked Christmas Tree Cookies

Directions

1. Preheat oven to 350°. Place cookie dough in a large bowl; let stand at room temperature to soften, 5-10 minutes. Beat in vanilla. Add flour; beat until blended.
2. On a lightly floured surface, roll dough to 1/4-in. thickness. Using a floured 2-in. round cookie cutter, cut out 18 cookies. Repeat with 1-1/2-in. and 1-in. round cookie cutters. For remaining dough, use a floured 1/2-in. star-shaped cookie cutter to cut out 9 stars.
3. Sprinkle round cookies with colored sugar. Place 1 in. apart on ungreased baking sheets. Bake until edges are light brown, 6-9 minutes. Remove to wire racks to cool completely.
4. For each Christmas tree, pipe frosting on top of a Rolo candy for a trunk; top with a 2-in. cookie. Pipe frosting on top and bottom of a Necco wafer; place in center of cookie. Top with another 2-in. cookie. Repeat layers with two 1-1/2-in. cookies and two 1-in. cookies, using Smarties between the smaller layers.
5. For stars, color a small amount of frosting yellow and pipe onto cookies; attach to the tops of trees using additional frosting. Thin remaining frosting with water; drizzle over edges. Decorate with nonpareils.
