Avocado meat replaces butter as the fat in this frosting. The cake is rich and moist with a hint of espresso.

The frosting balances perfectly with it sweet with a hint of citrus and a definite avocado flavour. When topped with toasted walnut and dark chocolate shavings, this cake has a beautiful, slightly unusual flavour and texture and is rich in healthy fats.
