The thread about the teenager putting on weight at school got me thinking about my own school dinners and the utterly incredible Tottenham cake my school used to serve, beautiful light sponge with thick set icing and sprinkles.
Despite my repeated attempts at baking it I have never been able to replicate it (although that could be my baking skills, or lack of) and I don't think I've seen it in the shops either, so does anywhere actually sell it?
