Making a Giant Cupcake

GuruOnAMountain

I know a few guys on here are bakers so I thought I'd ask your advice. I'm making a giant cupcake cake for my sister's birthday and she told me she's going to take the cake into school to share with her colleagues so I want to make it good!

I've got a baking tin but was looking for advice on what cake recipe to use? I'm wanting one that seems light but is firm enough to hold its shape.
