Where can I get a plain white cake?

[a]

I'm looking for a plain white cake, 3 tiers, to decorate myself for a first birthday party. Closest I can find is M&S: http://www.marksandspencer.com/traditional-wedding...

A large, medium and small tier would total £54 which is ideal.
But they are slightly decorated on top, and I would like one that's just plain.

Cake shops that I've approached want £200+ which is too much.

Where should I look?

Make one?

Have a search for 'decorate your own cake' on the internet.

Waitrose do a 20 person plain white iced sponge, Sainsburys do an 8 person plain white sponge. I am sure there will be others that do too.

I've seen plain cakes for decoration in Supermarkets. This is one...

It's not exactly what you are after...

But they are a very helpful bunch (I have used them a few times) and if you explain what you want they might be able to come up with what you need.

Just cover the M&S ones again, hide the decoration, it's minimal. What are you decorating it with yourself? Might be able to hide it...
