I want to make a cake tin that's a few big letters. As a one-off, I don't want to go searching and have to buy custom tins each time something like this comes around. So...
The magic of seach hasn't been so magic. Cake tins with squares you can make shapes with, but only if you want super low res pixel art. Otherwise lots of assembly, sticking together strips of cake you bake.
I did find this. tl;dr - cut cardboard base to shape, make walls with tinfoil. But pretty damn fiddly to do, and perhaps if you're going to finish with all that masking tape anyway, why bother with half what he does.
Anybody have any ideas or a winning strategy?
