The bottom tier is chocolate, filled with chocolate ganache and iced with vanilla buttercream. R2D2 is white cake with a strawberry filling and also iced with vanilla buttercream. Covered and decorated with marshmallow fondant. I also made the angry birds out of marshmallow fondant. *Original design from The Crafty Cakery (http://www.craftycakery.com/index.html)
Keep calm and bake on.
