Any ideas for a cake shaped like a trophy?

What about using the guitar-shaped pan turned upside down (with the wide end at the top) and drawing what you want on the trophy?

I will look into that cake pan. Thanks for the suggestion!

You could maybe make it 3D and use a rectangular/square base and then use the wilton sportball cut on half and hollowed out abit. Make cardboard handles and cover with buttercream stars. Just a suggestion!!
