1Heat oven to 350°F. In small bowl, mix green dough ingredients until well blended. Place dough in decorating bag fitted with small writing tip; set aside.
2Work with half of dough at a time; keep remaining dough refrigerated. On lightly floured work surface, roll out dough with rolling pin to 1/4-inch thickness. Cut with 2 1/2- to 3 1/2-inch tree-shaped cookie cutter; place 2 inches apart on ungreased cookie sheets.
3Squeeze decorating bag to pipe green dough around outer edge of each tree cookie; pipe dots randomly in center. Top each dot with candy sprinkle.
4Bake 9 to 11 minutes or until light golden brown. Cool 1 minute; remove from cookie sheets.
