Cupcake holder: Keep a few small margarine containers. A cupcake or muffin fits perfectly in them when you’re packing a lunch. Keeps them from getting smashed.
A round reusable Ziploc (or Glad or Rubbermaid) container works well, too. Place the cupcake on the lid and use the container as a dome. There are 9 oz clear plastic parfait/cupcake cups with lids, too.
