Icing Recipe

I am looking for a good icing recipe to compliment a fudge chocolate cake. Yesterday I made my first Barbie Cake for my 4 year olds birthday party. You moms of little girls will know the cake. It's the one where the cake is the dress and you stick a Barbie head and torso on the top of the dress. The cake recipe that I used was from Southern Living and it was delicious. But I wasn't as sold on the Vanilla Buttercream icing that went with it. It was too sugary for me. Any suggestions of something that might go better? This will definitely be my new go to chocolate cake recipe.
