Just buy one, or find some old biddy on the road you live on to make you one.
Or, join a church and go to some service or whatever and see if they have any cake?
Once you have found a good cake maker, treat her well, get her some nice biscuits, spend some time with her and get her making you some cakes.
I still need to find me a good flapjack maker, one that puts dates into the middle.
Theres a garden centre near-ish me that sells it, but i cant be bothered to ride there every day.
Someone at an open TT i did had made some, i wasnt sure which lady did though, there was 4/5 of them, i dont think i could of handled all that cake!
