Wrap a full sized chocolate bar with white wrapping paper and draw on the faces. For the earmuffs, use a black pipe cleaner and pom poms. Use buttons or black puffy paint and a cute ribbon and tag to complete the look.
What a SUPER CUTE IDEA: Use inexpensive aluminum cutters to turn out ornaments faster than you can bake a batch of cookies. Choose patterned papers or color-photocopy pictures onto card stock. Trace cutter on top; cut out. Dab white craft glue along cutter's edge. Press paper in place; let dry. Thread narrow ribbon through needle; poke between paper and cutter, and wrap ribbon around top of cutter. Slip a bead over ribbon's ends; knot.
