I need some suggestions for how to package and transport cupcakes for weddings, graduations, etc.  Right now I am borrowing full size sheet pans from where I work.  What do you all do?  I'm talking over 100 cupcakes to be transported.  Please help.

Sorry, I've never transported more than a dozen cupcakes (cakes only) and I have a carrier form that many.

Underbed storage containers. Liner with the grippy plastic rubber liner. Covered, safe....done!

CHEAPO version:

From the grocery store, get cardboard "trays". Like under Gatorade bottles. Cover in foil to be foodsafe.  The grippy liners are at my dollar store. You can cover with cling film.

It just depends on how professionally you want to present. ...or how often.

Ditto on the under bed storage containers! I had to transport 700 cupcakes to my daughter's school and that is just what I bought to do it. I was able to fit 90 in the size that I bought.
