One question I got asked a lot was if it was possible to make it a sphere. Absolutely it is. If you can make the hemisphere a sphere is easy. I didn’t want to make another Earth cake as I hate repeating bakes, so I opted to decorate it as something new. I threw around a few ideas ranging from something floral to a giant pokéball, but in the end I just wanted to make another planet.
Choosing a favourite planet was tough. As a kid I was fiercely passionate about two things: animals and the solar system. I ended up following the path of the former and never kept up to date with the latter, but the inner passion for astronomy has never died. Space is just so freaking cool. Our solar system alone is filled with so many fascinating planets, dwarf planets and all their satellites — choosing just one felt treacherous.
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. … 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.
