Method (Makes 24 cupcakes):
Place the cake mix, water and oil into a bowl and mix well for 1-2 minutes.
Place 24 paper cupcake cases into a cupcake baking tray, and spoon the cake batter evenly between them.
Bake in a preheated oven 180°C (360°F, Gas Mark 5) for 18 – 20 minutes until golden in colour and firm to the touch.
Allow to cool before decorating each cupcake.
For the topping, cream the butter or margarine in a bowl until soft.
Melt the chocolate either over hot water or carefully in the microwave (watching it to make sure you don’t burn it), add to your butter or margarine and then add the sifted icing sugar and water.
Pipe onto the cupcakes and decorate with your chosen decorations.
Alternatively you can use a ‘ready-made’ chocolate topping/ frosting.
