My son is a diehard Trekkie, and begged me to make him a Starship Enterprise cake for his 4th birthday. The bottom is a one-layer 9x13 covered in MM fondant and swirled petal dust to look like outer space; the upper layer is an 8" round that I baked in a pie pan instead of a cake pan for a more angled dimension on the outer walls. All decoration is fondant and petal dust, with food coloring marker used for the lettering.
