When I used to take cake into the office, I'd put it in a box on a layer of bubble wrap, and then use kitchen towel to 'pad out' the cake. The benefit being the kitchen towel can be used afterwards for fingers etc.
Then the box on the rack with a padded jacket under the box / over the rack.
Let your tyres down a bit, choose your lines, cake makes it in one piece.
Was half expecting to have mick taken out of me (I could see the jelly idea actually working, with say a sheet put across the top) but this is very helpful - thank you!
