Here is a coffee-flavoured icing that is ideal for cakes and pastries. While coffee is much loved by adults, it is also an acceptable treat for kids occasionally, so you can use this to prepare desserts to be served at parties. The combination of icing sugar and butter gives the coffee butter icing a lovely texture, which should be used smartly for best results. Always use the icing as soon as it is made, before it hardens; and spread it with a damp palette knife for a nice, smooth finish. Enjoy this lovely icing on your favourite cakes
