250g cream cheese at room temp
125g soft butter
2/3 cup castor sugar
Beat cream cheese and castor sugar till there are no lumps and well combined. Add butter and beat till very well combined. Add flavour and beat again. If you add too much liquid (flavour) it can go runny. Put in fridge for half hour and it will be good to go.
To give the frosting different flavours – use lemon rind, or 5ml vanilla essence, or 25g melted chocolate, or 30ml coffee essence.
