...we used to have cakes something of the same kind at home, when I was a girl, but they called them singing hinnies. They are famous at Saltburn for their fat rascals.
The origin of the name is obscure, it is known in this context at least since the 1855 Glossary of Yorkshire Words and Phrases Collected in Whitby and the Neighbourhood of 1855 where the definition of 'Spice Cake' is given as; "tea cakes with currants as well as cakes more generally, known as plum cakes for which this quarter is famous. The tea cakes made rich with butter and cream are called fat rascals."
