How do you make a microwave Victoria sponge cake?
Firstly, take an ordinary household Microwave to Victoria, then (and this is the tricky part) give it Artificial Intelligence. Next, let it hang out with the homeless alcoholics and junkies who frequent the area, so it learns how to sponge. Finally, force it to sponge cake from people coming out of Sainsburys. You may have to brainwash it or something in order to make it do your bidding, but basically that’s all there is to it.
