A decadent chocolate frosting and filling. This quantity is easy enough to make as needed, but you can also leave it at room temperature in an airtight container for a few hours or overnight. Stir it smooth again before using.
Note Makes enough to frost a 20cm round cake. This recipe is from Sweet Envy ($45, hbk) by Alistair Wise and Teena Kearney-Wise, published by Murdoch Books, and has been reproduced with minor GT style changes.
