Baking Dad: Space Shuttle Birthday Cake

Baking Dad: Space Shuttle Birthday Cake

As I mentioned previously, for his 6th Birthday last week my son requested a Space Shuttle cake to go along with the general, ongoing “I want to be an astronaut!” theme to his life.

Not gonna lie, I’m really pleased with how this one turned out.

I made my own fondant again this year to use on this cake* out of marshmallows, and it worked really well and tastes WAY better than the store-bought stuff. If you’re interested in trying it, here’s the recipe:

Easy Marshmallow Fondant

You need:

  • 8 oz. mini marshmallows (about 4 cups)
  • 2 tablespoons water
  • 16 oz. (1 lb) powdered sugar plus plenty more for dusting.


  1. In a large, microwave-safe bowl, microwave the marshmallows and water on high for about 1 minute, then stir with a rubber spatula (will be very sticky).
  2. Microwave for another 30-45 seconds, until lump free and smooth.
  3. Dust your work space liberally with powdered sugar.
  4. Optional: If you want to make the whole batch one color (other than white) or want to add additional flavoring, this is a good time to add a few drops of food coloring or your extract of choice. You can always color small batches later as well.
  5. Add the powdered sugar to the bowl and stir until combined and it becomes difficult to keep stirring. It will still be lumpy and sticky and warm.
  6. Dump out mixture onto your work surface, and knead with your hands, adding more powdered sugar if necessary until smooth and no longer sticky. Form into a smooth ball and wrap tightly in plastic wrap until ready to use, or store until later.

* For anything that isn’t black, that is. I tried making black fondant before, and it just takes too much food coloring, so I buy some black fondant from Duff instead and it works great.
