I made my first whoopie pie when I was about 12 and they were the ‘new craze’. I had no marshmallow fluff so the filling was properly sad and they were very strange. There are 2 things that put me off making them.
1. They have plain yoghurt in. Now I like yoghurt, but they don’t sell it in the corner shop and we never just have it in the fridge so it means I have to be organised. I’m not organised. So I never have the right ingredients…
2.They have a ridiculous name. I’m sorry, but which creative person made up the name ‘whoopie pie’? Its not even a pie! It annoys me no end. Some one eats one and asks what they are, how stupid do you sound saying, ‘oh its a whoopie pie’. One of my pet hates. Such a stupid name for an awesome food. The spell checker won’t even accept it, that’s how rubbish it is.
Moans aside, this attempt was so much better. Almost cookie like, soft centred cake sandwiched together with fluffy marshmallow cream. So yummy, took them to youth group and had to hoover up the crumbs but it was worth it
I found marshmallow fluff so hard to come by, I can’t believe they don’t sell it in normal UK supermarkets! I think the should…

For the Sponge
1 large egg
150g (5.5ozs) Caster Sugar
125g (4.5ozs) Plain yoghurt
25ml (1fl oz) whole milk
¼ tsp vanilla essence ( I used extract)
75g (2.5oz) melted unsalted butter
200g (7oz) Plain Flour
80g (3oz) Cocoa Powder
¾ tsp bicarbonate of soda
¼ tsp baking powder
Filling
170g (6oz) unsalted butter
280g (10oz) icing sugar
220g (8oz) vanilla marshmallow fluff
Method
1/ Using a mixer cream the egg and sugar until fluffy. Pour the milk, yoghurt and vanilla essence into a bowl and mix together. Then add this mixture in with the beaten egg an sugar. Finally add in the melted butter and mix in thoroughly.
2/ Sift together the remaining dry ingredients, and then to the creamed mixture and mix well on a medium speed.
3/ Now place the batter mix in the fridge to rest for 20-30 minutes.
4/ Pre-heat the oven to 170C (325F), Gas Mark 3 and cover two baking trays with baking parchment.
4/ Once rested, spoon or pipe onto the baking trays making 8-10 mounds per tray. These need to be 2-3 cm spaced apart and around 3 -5 cm in diameter.
5/ Bake for 10-13 minutes or until they spring back when touched.
6/ Remove from the trays and place on a wire rack. They need to be completely cool before adding any filling to them.
7/ To make the filling mix the butter and icing sugar together using a hand whisk or standing mixer. Once this is blended add the marshmallow fluff and then mix on a high speed until the mixture is light and fluffy. Place in the fridge for 30 minutes as this will firm up the mixture slightly.
8/ To sandwich the pies, take one sponge and spread a tablespoon of filling on one flat side. Follow this with sticking another sponge, flat side down onto the filling to make a sandwich. Continue this process to make the other whoopee pies.
