Pre-heat the oven to 200C/400F/Gas 6. Get about 18 paper cases ready.
Measure all the ingredients into a large bowl and beat well for 2-3minutes until the mixture is well blended. Half fill the paper cases with mixture.
Bake for about 15-20 minutes until the cakes are well risen and golden brown. Allow to cool.
For the icing beat the butter until it is soft, add the Icing sugar and mix until smooth.
Cut a slice from the top of each cake and cut this slice n half. Pipe a swirl of butter cream into the centre of each cake and place the half slices into the butter cream at a fairy like wings.
