How to Make Space Cakes?

To make a space cake, you first have to train to be an astronaut, or wait until space travel is the norm. Then, once up there, mix up your flour, eggs, sugar and butter to a nice batter and add your desired flavorings, perhaps melted chocolate, or pureed strawberries. You have to adjust the recipe for altitude, so it would probably have to cook for a couple of days at 40 degrees. It would be much better to eat regular earth bound, additive free cake and be healthy.
