My son asked for a solar system cake this year and I realized I’d have to learn how to make a fondant if I was going to have a modicum of success at making planets. He’d seen a picture online and had his heart set, and I was determined not to let him down.
It’s just a regular box cake, chocolate, per his request. To make the background dark to represent space, I added some blue gel color to chocolate frosting.
For the planets, I made fondant from a recipe I found online and that worked out really well. Whew! I used gel color for their coloring as well. It really was fun to work with, if a bit on the messy side. The gel color washed off very easily though, so that was good.
For stars, my son picked out some little pearl cake decorations.
I think I was a little enthusiastic on making my planets! LOL They’re a little on the big side, too big to fit nicely across a 13×9 cake, so my scale is off. But my son was happy, and I did manage to leave at least enough room to put his name and age, if not the whole Happy Birthday part.
