Can I have some cake recipe suggestions please?

[HiccupHaddockHorrendous]

I'm going to visits some friends and their new baby in about three hours.

I'd like to make a cake but have limited ingredients.

Things I don't have or can't use:
Butter
Vanilla essence/extract (or anything with alcohol in it)
Anything with animal product in it

Any suggestions or should I just pop to Tesco/Asda on my way?

I expect you are there now so this is for next time vegan cake recipes
Some nice choccy ones.
