As with most things on the UK, probably. I definitely used Bobbins.
I used to think everyone called (cobs|bread cakes|rolls|barns) muffins, and it turns out it was just my small town that did it. As in, just my small town, not region, county, etc.
It's definitely chip muffin. I have no patience for those heretics up the road with their chip barms.
does that area have a textile manufacturing history?
I ask because i'm only familiar with a thread/yarn bobbin, I wonder if it derived from that.

UK regional dialects are summed up really well here because despite listing five different names for a specific thing you still neglected the word I use (baps).
If you call it a teacake, and I say no those have raisins in, and you protest that's a fruit teacake, I know you're probably from Burnley: https://www.ourdialects.uk/maps/bread/
