Moon-Landing Cake

For his 5th birthday, my son wanted an outer space astronaut training party. He was very excited to “train” to go into outer space and was almost as excited to eat his outer space moon cake. For his cake, I made a moon-landing cake, complete with planets, astronauts, and a moon buggy.

Supplies

Here’s what you’ll need to create an outer-space cake:

  • 3–4 boxes of cake batter
  • 3 tubs of vanilla frosting
  • food dye
  • 1 tube of black frosting
  • crushed Oreos (1 cup)
  • pearlized sprinkles
  • Outerspace props (astronaut, space buggy, rocket, or American flag).

The Cake

  • Bake a cake in a 12x18 sheet cake pan. For a 12x18 sheet cake, use 2–3 boxes of cake mix (or the equivalent of 14 cups of cake. Basically, fill the pan a little more than halfway). Placing a piece of parchment paper at the bottom of the pancake helps the cake come out easily once it is cooled. For this cake, choose your favorite flavor.
  • Bake the planets in different-sized glass bowls. Pick out 5 different-sized bowls and bake 2 each for the 3 round planets, moon, and earth. I used bowls from my set of nesting glass bowls. Remember, these will cook much faster than regular cakes because they are smaller. Check them regularly until done. If a dome forms on top, use a knife to flatten it after the cake has cooled.
  • Freeze the cake. Once it has cooled, wrap the cake in a layer of wax or parchment paper and then in a layer of tin foil. If you plan to freeze it overnight, this should suffice. If you plan to freeze it longer than 24 hours, I suggest also wrapping it in plastic wrap to keep the freshness in.

Steps for Decorating the Cake

  1. Prepare each frosting color by adding food dye to the frosting. You will need dark blue, orange, pink/red, yellow, light blue, green, and white (plain). Use different containers for each color, and make a little more than you think you’ll need for each planet since it can be difficult to match your color if you need more.
  2. Prepare the “moon” frosting by adding crushed Oreos to the vanilla frosting.
  3. Frost the entire cake with the dark blue frosting.
  4. Frost the planets. For each planet, use some plain vanilla frosting as your “glue” to add the two semi-circle cake pieces together. Using a metal skewer to hold the two semi-circles together, frost the outside of the planets with each color. Again, having frozen cake pieces will make this much easier.
  5. Frost the earth. Using the method described above for frosting the planets, frost the earth light blue. Using a cake knife, swirl little bits of green and white to resemble the continents and clouds.
  6. Place the planets, moon, and earth in the appropriate places on your cake.
  7. Place the astronaut, rocket, and moon buggy on the cake.
  8. Pipe on your birthday message.
  9. Add the pearlized sprinkles.

Happy Decorating!

Frosting an Outerspace moon landing cake is fun and easy. One great thing about this cake is that the frosting can be a little “bumpy” and imperfect. Use your imagination to add personal touches. Enjoy your trip to the moon!
