I made this for my friend's Adoption Shower. She is decorating the nursery based on Eric Carle's book. I tried to get permission from Eric Carle's people for this cake. They gave me permission to make it, but not to sell it, so I did it for free. Top tier (8") is Vanilla Chai cake with vanilla chai buttercream filling. The bottom tier (12") is pistachio chocolate chip cake with chocolate fudge filling. All buttercream.
