Place the foam cone on a cake round.
Using the toothpicks placed in the OREO Cookie Balls, gently press them into the foam cone forming a Christmas tree.
When all of the green OREO Cookie balls have been placed in the tree, place the yellow OREO Cookie Ball at the very top for the star.
To decorate the tree simply place a small amount of chocolate on a colored candy ball or candy light and press onto a green OREO Cookie ball. Hold in place for 5-7 seconds or until it sticks.
Once you have finished decorating place in the refrigerator until it's time to use as an edible centerpiece.
