I spent an entire week after work and most of the weekend working on this cake. It took me a total of 29 hours (not including the baking). I individually made all of the gum paste decorations and frosted the sides of the cake with buttercream. This cake is a 3 layered yellow cake with blackberry mousse filling and buttercream frosting. The gum paste decoration is a blackberry bush cascading down the side of the cake.
