The cake itself is a chocolate cake with Oreo buttercream filling. It's frosted with buttercream in the form of about 1 zillion stars. These cakes tend to take so much time, but they really look great when they're done.
Because I had to cut so much away from the cake to make the R2D2 shape, I had a lot of cake scraps left which I then made into some "spacey" cake pops. Black sugar with a few white sprinkles reminded me of outer space. I hope that translated well!
Happy Birthday to you, Isaac! I'm so honored to have been a part of it!
