I'm making a Triple Chocolate Celebration Cake that I found on the Epicurious site for my mom's birthday. It calls for 3.5 lbs of chocolate (for ganache, mousse filling). When using good chocolate -- it can be about $30 just for the chocolate alone -- not to mention all of the other ingredients. A little too spendy for me. I am going to make the recipe for the cake part. But does anyone have any alternitive ideas for fillings/frostings that won't cost me a fortune??
