I just iced my cake with the icing and dusted it with extra icing sugar, but I wish I would have read the directions closer and used 2 cake pans so I could ice it the way they suggested - they put the chocolate icing in between the two cakes (stacked on top of eachother), and then made a second icing for the rest of the cake:
1/2 c. apricot jam
2 tbsp. cocoa
3/4 c. icing sugar
Melt the jam over low heat and spread it over the top and sides of the cake. Sift cocoa and icing sugar together and add a little water at a time. Spread over the cake.
That would have been delicous, but considering I have a hard time icing a cake the regular way, these extra steps may have resulted in a puddle of chocolate and apricot jam blobbed onto my cake. So even though I'm sure it would taste fabulous, I'm pretty happy with the way mine turned out.
