You successfully resisted eating too many holiday treats at the book club cookie exchange. Throw a cookie party for yourself with this guilt-free Christmas tree cookie. Unwrap your cookie and cut a tree from it using a 2 ½ inch cookie cutter. Eat the scraps while stirring powdered sugar, orange juice and a drop of food coloring in a small bowl. Decorate with icing and mini candies. Tis the season, after all.
