What a wonderful comment! I am going to call on a friend @makinstuff to see if he has any ideas, if not I have a grandpa who is a machinist and I think we help you invent something. You've come this far!
I will think on Cadbury, I might just call up the marketing department and see how far I can get...
Cheers! (a big salty cheers!)
Steem seems to be glitching and refuses to let me comment on your last reply. Hopefully this one makes the cut. The cookies are about half a cm in diameter once baked, so they're a little smaller in the press, though I think I can get away with them being slightly bigger. Thanks so much to you and @makingstuff for the help! (I'll post you some bars once I've got a production line figured out!)
