Cookie Christmas Tree
Heat the oven to 350°F. Line 3 baking trays with non-stick baking paper.
Roll out the dough thinly on a lightly floured surface.
Cut out stars using star-shaped cookie cutters in graduated sizes; the smallest cutter should be about 1 1/2" and the largest about 4".
Spread the icing on the stars and place the largest stars on a serving plate. Place the next largest stars on top, pressing down slightly so the icing holds them together. Repeat with the remaining stars in order of size, finishing with the smallest stars at the top.
Place an upright star at the top of the tower.
