I made these for my sons birthday at school. I used the silver cupcake liners and tinted my icing gray to add to the "ufo" effect. I put a large marshmallow in the middle with a gumdrop on top. The "lights" around it are plain m&m's. The little green men are gummy candies i found in the candy aisle, I cut the bodies off and attached the heads to the marshmallow.
