As you know my son is having a Star Wars party (...in just 2 days)! He requested an R2D2 cake, so this is my attempt at it. This cake was not difficult to make but it was REALLY time consuming. I broke it up into a couple of days; one for baking, one for assembling, and one for the details. If I did it again, I'd make two attempts at the details. My hand was really sore after all of the piping.
So here's what I did...I made one cake in a glass bowl for the top of his head. I also made 4 eight inch round cakes. I stacked the rounds with frosting in between the layers and I added several dowels for support. Then I placed the head on top. I did a quick crumb coat and put it back in the fridge. After about twenty minutes I put a smooth layer of white icing all around the cake. I did this before I added the legs so I could get it as smooth as possible.
Next I used store bought Rice Crispy Treats for the legs. I used 2 on each side for the height. I rounded the tops and then added little triangles to the bottom to give his legs the right shape. I attached the legs with frosting and put a layer of frosting on the outside of them too. Then I put R2 back in the refrigerator until the next day.
