Classic Whoopie

Hannah Miles: "These chocolate and marshmallow pies are a true classic. Also known as ‘Gobs’ or ‘Black and Whites,’ they have a rich chocolate flavour with a creamy marshmallow filling. Sugary sweet and seriously addictive, I promise one bite and you will be hooked! Marshmallow fluff is available in delicatessens and some supermarkets – it is very similar to the creamy white filling you find in the centre of a walnut whip, utterly calorific but quite delicious!"
