Where can I get thin round chocolate wafers / biscuits?

[SpawnChorus]

I'm going to make this cake:

The biscuits in question appear at approx 4 mins.

No idea! But you could have a go at making something like this, then dipping them in chocolate and leaving them to set on greaseproof paper?

Can't remember who makes them, but I've seen tubs of choccy things, a bit like pringles. Seem to remember they were in mint or orange.

Would they work?

Had a search, they're Cadbury and called 'snaps' and are in choc, orange, hazlenut and mint versions

or Rococo if you want to go posh
