“I made these for a company bake-off and won first prize. This is time consuming, but is one of the most fabulous chocolate desserts I have ever made! It can be made with or without the ganache topping, but I strongly suggest that you make it totally awesome by adding the ganche! Don't eat too many -- they are rich!”
