We used the Whoopie pie recipe from the Hummingbird Bakery cookery book which involves hunting down a jar of Marshmallow fluff for the filling. Luckily we already had a jar in the cupboard so the baking began.
The kids had great fun mixing up the cake ingredients but had even better fun when i let them lick the bowl of the filling leftovers. This gave me a 5 minutes for a peaceful cup of tea. Happiness all round.
This meant that some of the cake was left over and so the kids promptly polished that off. Not much lunch was eaten but everyone was happy!
