Cakecrumbs, creator of the amazing Earth Cake, has topped that marvel with a Jupiter layer cake whose layers reveal the theoretical makeup of the gas giant. Its multiple layers represent "a core comprised mostly of rock and ice… surrounded by a layer liquid metallic hydrogen, and the outer layer is composed of molecular hydrogen."
I detailed the atmosphere of Jupiter by covering the cake with ivory marshmallow fondant, then dry brushing a combination of ivory, brown and maroon edible ink. The top ended up being a bit more saturated as I was largely experimenting with colours at that point and was throwing in a bit of yellow. I ended up sticking mostly with ivory and adding extra detail with the brown. Once all the base colours were down I started removing colour to create the storms or other distinguishing features and topping it off with highlights. The whole process took about 8 hours with teeny tiny brushes.
…When my sister asked me what I was making and I said Jupiter, she said to me, "I didn't even know Jupiter had layers." It's amazing how much we can forget after learning it in primary school. So here's a rehashing for those of you who've also forgotten. Our knowledge is mostly theoretical of course, but the gas giants are thought to have a core comprised mostly of rock and ice. This is surrounded by a layer liquid metallic hydrogen, and the outer layer is composed of molecular hydrogen. *cake is totally not to scale
In cake speak, this translates to a core made of mudcake, surrounded by almond butter cake, surrounded by a tinted vanilla Madeira sponge. There's a crumb coat of vanilla buttercream underneath the fondant.
