This was made for my husband's co-worker. Chocolate cake with vanilla mousse filling. The buttercream icing is one I found in an old Wilton yearbook called "deluxe buttercream". The recipient of the cake, who has had my cakes before, said it was the best icing I have made..........hmmm, may have stumbled on something here! Flowers & leaves are marshmallow fondant. Side note: the Wilton "extra special buttercream" recipe is the same as the "deluxe" one I found in the old issue. I just added 2/3C cocoa.
