Snip off the ends of 9 chocolate Twizzlers to expose the hollow center. Thread wire through the centers and trim the wire so it's hidden. Bunch the Twizzlers together and wrap a piece of wire around the center, toward one end. Bend out the shorter half to form a tree base that can stand up. Bend the taller limbs to form wild tree branches.* Place the tree on the cookie base and stick M&M's around the roots.

*Remove wire before eating.
