Grace’s sixth birthday is a space themed extravaganza so I made a galaxy cake. It’s more of a solar system cake, but not our solar system.
The cake is a six layer stacked extreme chocolate cake. A cardboard cake board separates each two layers to make cutting and serving easier. Each layer is a 9” round cake, and the “internal” cake board is 8” to allow a smooth buttercream transition between layers. The small white stars are tempered white chocolate made with a silicon mold. The larger stars, around the base, are various colors of white chocolate, again formed using a silicon mold.
The planets are white chocolate made with a variety of hemispherical silicon molds and painted with decorating colors mixed with vodka. Some of them were fused together to make spheres, the ones on the side of the cake were left as hemispheres. Slightly melting the edges of the hemisphere or the bottom of the spheres helped them adhere to the blue buttercream.
Before adding the planets I splattered the cake with white food coloring. The “space woman” was purchased and a printable decal image of Grace was pasted on the silver faceplate of the space suit.
