My niece Caitlin turned five recently and initially requested a Space Invaders themed birthday cake. After contemplating how time consuming the production of an army of alien invaders would be, I asked if there was anything else she might want. Luckily, she currently loves the Solar System and this planet-filled birthday cake was born.
Showcasing all eight planets meant that much surface area was needed. A 10" x 15" x 2" slab of chocolate cake, dark chocolate ganache, and raspberry mousseline was assembled and glazed with a shiny chocolate glaze in order to resemble the deepest darkest depths of the universe.
Mercury, Venus, Earth and Mars were simply little balls of fondant, whereas Jupiter, Saturn, Uranus, and Neptune were Rice Krispie domes covered in fondant and later airbrushed. I did try hard to maintain the relative scale of each planet in terms of size and distance from the sun but alas, some creative license was taken.
Feeling sorry for poor Pluto's recent demotion, I decided to include Pluto by hiding it on the side of the cake near the bottom edge. Can you see that little grayish blob in the above photo? Happy Birthday Caitlin!
