How do you make a tree out of frosting?

To make a tree out of frosting, start by using a piping bag fitted with a star tip to create the tree's shape. Begin at the base and pipe larger star-shaped peaks, gradually making them smaller as you move up to form a conical shape. For added detail, you can use different shades of green frosting for texture and decorate with candy or edible glitter to represent ornaments or lights. Finally, you can add a brown frosting base for the trunk to complete the look.
