It sounds weird, doesn't it, but there have been versions of cola cakes around for decades! The original one, loaded with marshmallows and nuts can be found on the Coca-Cola website but I didn't have those extra bits so I've used James Martin's version.
Instead of making a sheet cake, James' cake is made in a round pan. It looks a bit more elegant but it's still very moist and very rich.
The topping couldn't be easier to make and it's poured over the cake while still warm in the pan!
If you have a can of cola rattling 'round your fridge, give cola cake a try. If you love rich, moist chocolate cake you'll love this!
