When my son wanted a Star Wars theme for his 8th birthday, I started researching cakes on this site. I quickly decided on a R2D2 cake because I wanted to make a 3D cake, but I couldn’t find any that I was crazy about. Still, I got lots of ideas. This cake was only difficult in the assembly. The frosting was “a piece of cake”!
I used white and grey buttercream frosting and a knife frequently dipped in warm water to make it smooth. I bought pre-colored blue fondant for the details and used candy for the red lights. The cake itself is 3 small round cakes with a half ball pan on top. I recommend using dowels and putting a round piece of cardboard under the second layer to keep it from sinking.
For the legs I made a small sheet cake and cut out pieces. This is much easier to do after freezing. I attached these with chopsticks that I cut into smaller pieces. It’s helpful to have a small R2 toy or at least a picture of R2 next to you when you’re working.
This was one of my favorite cakes to make and my kids reactions when they came down in the morning to see it were better than Christmas morning! Everyone loved this cake. The kids and parents were amazed because it looked so real. The hardest part was having to cut into it.
Good luck and may the force be with you!
