Cream-cheese frosting for cupcakes

This is really a buttercream icing, made with cream cheese rather than purely butter, which cuts the sweetness a bit.

• 11oz/300g cream cheese
• 2oz/60g butter at room temperature
• 1 tsp vanilla extract
• 12oz/340g icing sugar

Whizz all the ingredients together in a food processor. Chill for an hour or so before using.
