I have to disagree with you The Winner :)
Nelsons square is a Norfolk cake .Sometimes called Nelsons slices .After Admiral Lord Nelson our most famous son .
Used to be very popular round here in the bakers shops but we don't have many bakers shops left !
Similar to bread pudding .
That's OK to disagree with me shaneystar2. It is obviously a local cake, as I have never heard of it. As stated, it was my suggestion. Not a definitive answer.
