I made this for my son's 5th birthday party that was held at an Air & Space Museum last Fall. It's been my favorite cake to do because I love outer space and because it was for my little guy. He loved watching me create everything for him and even helped design the aliens. The shuttle was carved out of vanilla cake then covered with MMF. The tail fin was fondant covered cardboard but all other shuttle details were edible fondant. The moon was carved from a 10" round chocolate cake & covered in BC. The alien spaceship was RKT covered with fondant. The aliens and astronaut were hand modeled from fondant. I got the idea for the aliens' sign from a cake on this site. My son loved that he was the astronaut floating in space. The astronaut's face shield is gelatin. I used various colors of luster dust, petal dust, & disco dust for the stars and galaxies decorating the 20"x30" MMF covered plywood board. This was my first time to carve cake and cover with fondant. TFL!
