They’re usually called cake tins or cake pans. If you mean the deeper metal boxes used to bake and sometimes store cakes, people also call them baking tins , cake molds , or square/rectangular cake pans.

Common names

  • Cake tin : common in everyday English, especially for metal bakeware.
  • Cake pan : the most widely used term in US English.
  • Cake mold : used when the item is more of a shaped form than a standard pan.
  • Cake box : usually means packaging for carrying cake, not the baking container itself.

Small note

If by “dice cake boxes” you meant the box-shaped storage item for a novelty cake or a dice-themed cake container, that’s a different thing from bakeware. In that case, the usual term would be cake box or cake carrier , not the pan itself.
