HTH

Just made some - yummmm.

Ganache -
Heat 1/2 cup cream until boiling. Pour over 6 oz. chocolate (I use 60% Ghiradelli Chocolate Chips.). Stir until chocolate is melted. Let cool 15 minutes.

Buttercream -

Beat 9 oz. softened, unsalted butter about 2 minutes in electric mixer. Add 4 cups powdered sugar. Then add 1 tsp. vanilla. Beat until light and fluffy. Slowly beat in the chocolate. You may need to chill it some before icing cake.

Go with Toba's -- to die for.

thanks for the replies!!
toba's sounds sooo good and I will definitely give it a try!
