Pipe 3-dimensional trees on parchment using the cupcake swirl technique. Let them dry, then pick them up and position them wherever you like around your gingerbread house!
This technique is like piping a cupcake swirl; however, the tree shape starts with a narrow base piping almost directly on top of the previous rotation to build a cone shape.
Finish the tree with nonpareils and a Gold Star Sprinkle.
