How to Make Planet-Shaped Cakes


For your next party, make a cake shaped like something other than the traditional rectangle, square or circle. For example, using ball-shaped, molded cake pans and frosting, you can create a cake that will look like a planet. Alternatively, use several smaller ball-shaped molds to make all the planets in our galaxy. Serve your finished cake or cakes for a planet-themed birthday or Earth Day party.

Things You'll Need

  • Cake mix
  • 3-D sports ball cake pan
  • Vegetable oil
  • Flour
  • Cooling rack
  • Serving platter
  • Serrated knife
  • Frosting
  • Piping bag
  • Prepare a cake mix according to package directions. Alternatively, make a cake from scratch using your preferred recipe. Although you can use any type of cake, pound cake works the best.

  • Rub the inside of a three dimensional sports ball cake pan using vegetable oil. Let the mold sit for three to five minutes. Wipe the excess oil out of the mold using a paper towel. Sprinkle the inside of the mold with flour. Shake the excess flour of the mold.

  • Pour the cake batter into the mold according to mold directions. Different molds have different directions, but most instruct you to pour the batter into one side and the place the other half of the mold on top.

  • Bake the cake in an oven pre-heated to 350 degrees F for 50 to 60 minutes. Remove the cake pan from the oven and place it on a cooling rack. Allow it to cool for five to 10 minutes. Remove one side of the cake mold. Leave it to cool another five minutes. Put the removed part of the mold back on, and flip the cake over. Remove the other part of the mold. Let it cool for another 30 minutes.

  • Take the cake out of both parts of the mold. Make sure the cake is completely cool before proceeding. If the cake still warm, leave it another 30 minutes to bring it to room temperature.

  • Place the round cake on a serving platter. If necessary, use a serrated knife to remove a small wedge from the bottom of the cake to keep it from rolling.

  • Cover the cake with colored frosting. Decorate the cakes using colored frosting in a piping bag. Alternatively, fill a plastic zip top bag with colored frosting and pipe the details on.

Tips & Warnings

  • Use small cake molds to make all the planets. This allows you to make all the planets in small, manageable sizes.
  • For the planet Mercury, use gray frosting. For Venus, use orange and yellow frosting. For Earth, use blue and green frosting. For Mars, use red frosting. For Jupiter, use sand frosting and add varied bands around the cake. Include a large spot on the cake, as well. For Saturn, use tan frosting. To create the rings, cut the rings out of cardboard and attach them to the cake with wooden skewers. For Uranus and Neptune, use blue frosting. Alternatively, use any color frosting desired to create a unique planet.
  • To add a marbled look to the planets, use an airbrush.
  • Alternatively, use colored, rolled fondant to cover the cakes.
