These cakes caused a bit of excitement in our house because I never usually ice anything! They have a delicate orange flavour (and a little bit of vitamin C if it survives the cooking process!)
Beat together the butter and sugar (I used an electric hand whisk), then beat in the orange zest and egg. Fold in flour then gradually mix in the milk and then orange juice.
Spoon mixture into cake cases and cook at 180 C for 16 - 20 mins.
I added a simple icing made of icing sugar, a drop of food colouring and a few drops of water mixed into a thick paste.
100 g butter, soft
80 g sugar
1/2 orange - zest and juice
200 g SR flour
100 ml milk
