Tiramisu HELP!!!

[Blablabla1984]

Hey ladies,
It's my hubby's birthday soon and his favourite dessert in tiramisu. I'd like to make a round tiramisu cake in a spring form pan.
The problem is we live in a village and I can't find ladyfingers. The only accessible buiscits are digestives, rich tea buiscits and a few more of that sort. Do you think they will hold up well? Thanks in advance x

Could you make plain sponge cake and use thin layers of that instead? I don't think normal biscuits would soak up the coffee/booze as well.

Do any major supermarkets deliver to you?

Use cake not biscuit!

All good ideas, thank you!!!! I think I'll go ahead with the cake. I could buy a plain or madeira cake, they sell that here too

Make the sponge fingers! They are super super easy and taste amazingly good. I am a tiramisu addict myself and I use this recipe for the fingers:

Make your own sponge fingers, really easy. If not can you get some trifle sponges as they'd work better than something like Madeira.

Do you have an Amazon account?

What about something like this:
