An update on previous thread about where to get a birthday cake made ...
I duly ordered a birthday cake from the shop Squeaver suggested - Dean and Hudson on Archway Road near Highgate Tube - and it was LOVELY!
I chose a plain sponge with buttercream and jam filling, square, with white icing - on which they superimposed an photo of DS's favourite toy, also made of icing, with Happy Birthday and various other little decorations iced on.
Another cake maker based Winchmore Hill contacted me via the original thread - she will get a test drive at the next party Chez Baldwin!
