Does anyone know this childhood rhyme?

[Walkthroughthefire]

For some reason the last line has popped into my head. My mum used to sing it to us (Scotland). The last line is: a treacle scone is far too hard to chew, achoo! Achoo! Achoo!
HELP? It's driving me mad!

I've googled to no avail and my mother isn't answering!

A regional variation of Pop goes the weasel?

Googling got me this which talks about a treacle scone being too tough, then a line about snuff making you sneeze, which feels like it must have some connection with your rhyme.

Is it another verse or regional variation of Ring A Ring O Rosie?
Which ends in 'atishoo atishoo we all fall down'
