These are really kid-friendly! Kids love cupcakes even if they're "plain," so fun decorations just add to their excitement. We made these for Halloween one year, except that we decorated them as ghosts instead of aliens (just use a white icing without food coloring, and omit the licorice antennas, using black piped icing to make eyes and a squiggly mouth). I made them myself the first time, since I don't really care much for messes in the kitchen (OCD... it's a curse!), but the second time we made them, I invited my 5 and 7 year old boys to help decorate them - we all had tons of fun! We shared them with some of the kids in our neighborhood that came over to play one afternoon, and they were such a hit that we had kids knocking on our door for several more days asking if they could have another cupcake. I'll have to keep an eye out for the little plastic cups to store these in... I tried to improvise with a deep baking pan and aluminum foil to keep them covered without ruining them.
