METHOD (Makes 12 – 15)
Place the lemon pieces into a food processor and blend to a pulp.
Place the cake mix, lemon pulp, sour cream and vegetable oil into a bowl and beat for 1-2 minutes to form a smooth batter.
Using a wide piping nozzle or spoon, pipe or spoon the mixture onto a large lined baking tray in walnut size balls, about 3-4cm (1-2 inches) apart.
Bake in a preheated oven 180°C (360°F, Gas Mark 4) for 10-12 minutes until soft and springy on top.
Leave to cool for a few minutes before transferring onto a wire tray.
For the “Filling”, heat the milk and marshmallow in a
saucepan over a low heat, stirring, until smooth. Then leave to cool.
Beat the butter until soft and creamy and then gradually blend into the marshmallow mixture until smooth.
Sandwich two whoopie cakes together with a tablespoon of the filling.
For the “Topping”, mix the icing sugar, with enough lemon juice together to achieve a smooth icing.
Spread a little icing onto each whoopie pie and decorate with the lemon zest.
Once filled they will keep for 24 hours.
