Solar System Cake


We finished our study of outer space by making this cool Solar System cake! One night at dinner I was brainstorming with the kids how to make a cake look like the sun and the planets. I was thinking I would do a rectangular cake with dark blue icing and draw the sun and planets with icing gel.

But dark blue frosting is very hard to make because icing starts white. And it seems like a lot of work to draw the sun and planets with frosting, especially if your hands start trembling because you want to make it perfect.

I could use candies for the different planets instead of drawing them, choosing the correct colors and sizes for the candy for each planet.

Suddenly a different idea it hit me: Bake one cake in a circle pan, and frost it yellow. Then make the planets cupcakes! “Brilliant!” I shouted at the dinner table, beginning to sing the Halleluyah chorus. The kids cheered, laughing hysterically at my singing. Of course the kids approved, since making cake means eating cake.


I cut a piece of cardboard slightly larger than the circle cake, taping foil on it, before plopping the cake down on it. After the cake cooled, we frosted it yellow. I placed gold-wrapped Rolo candies around the edge to make the sun fancy, but you could use any yellow candy.

I mixed different colors of icing, and I frosted the cupcakes according to the color of the planets. I frosted Mercury with chocolate frosting instead of trying to make gray frosting. (Yuck! Who would want to eat that?) The Earth cupcake was first frosted with blue, then green blobs for the continents. Jupiter was yellow with swirls of red. Saturn was yellow, and I stabbed a pink pipe cleaner as a ring around it. You could also use licorice.

I placed the Solar System cake on a dark blue sheet that I threw on the table, and I used white candy sprinkles for space dust. Don’t you just love it?

    This is brilliant in it’s simplicity! I love it – we will definitively be making this when we study the solar system! Thanks for a great idea!
