Aside from the fact that it looks the part on the outside—and is an accurate representation of the planet's interior structure—this cake is round. A round cake! When you take a look inside the cake, though, you'll see that it's actually its two semicircles put together, layered up to keep the shape. Still, it's an impressive effort, and it looks great.
The outer layer is marshmallow fondant bruited in edible ink, while the inner sponge is almond butter cake, vanilla Madeira sponge, and mudcake. This isn't Rhiannon's first attempt at a planetary cake: Back in May, our intrepid baker made a similar layer cake modeled after the Earth. If your mouth is watering at the prospect of taking out an entire planet in a few bites, check out Rhiannon's tutorial.
