Make Sweet Loren’s Christmas Tree Cookies To make the smallest sized cookies, break cookie disc in half and roll into into ball. Medium size: place 4 discs on 2nd cookie sheet. Large (base): place 1.5 discs on 3rd cookie sheet. Once cookies are cool, apply icing approx. 1” to the base, middle, and tree top to form tree shape. Generously decorate with sprinkles. Tip: top with a sprinkle stars if you have them!
