You can cover it with any chocolate icing, as it tastes even better.
This cake worked out great - the orange rind just comes through the chocolate flavour. I used 1 3/4 cups of sugar instead of 2 whole cups and we didn't use any icing, just added whipped cream and strawberries when serving. - 13 May 2012

This cake looked great when it had finished baking, however, it is not edible. The taste was terrible - it tasted of flour. The birds and other local wildlife were given this cake to eat as it is not fit for human consumption. - 16 Nov 2012
