Icing (that works for me!)

Icing that actually worked for me! Hopefully, not a once off occasion!

90g butter
1/4 tsp orange essence
1 cup icing sugar
1 tbsp milk
yellow, pink or orange food colouring

Beat butter and essence in a small bowl with an electric beater until light and fluffy. Beat in sifted icing sugar and milk in 2 batches. Beat in a little of the desired food colouring.
