This was for my husband's birthday. He requested an R2D2 cake, and I added a sound chip as a surprise. I decided to try a two legged version, and used the tutorial by Stacked Cakes in Canberra as a guide. Chocolate cake with chocolate buttercream and strawberry filling, covered in chocolate ganache under the fondant. The entire body and head is cake. The legs were built up using rice krispie treats.
