Oh no. Oh no. Oh no.

Oh Shit. Shit. Shit. Shit.

I have baked all the cakes. I have filled and marzipanned all the cakes. All lovely rich, moist chocolate cakes.

Just checked the order form and the middle tier is supposed to be vanilla madeira.

Shit.

I know how this error occured. I've been reading through e-mails from the customer and in one of them she told me how she went to a wedding and the wedding cake was horrible and there was loads of maripzan on it.... so I e-mailed her back and said did she want to change to all vanilla madeira? And she said no, she only likes chocolate. So I've had only chocolate on my mind.

I've been going through the options.

a) say nothing and give her all chocolate and hope she doesn't say anything afterwards. Not very nice or very professional.
b) bake another cake tonight. Possible. Will entail a trip to Tesco, but do-able.
c) phone customer, tell her what's happened and ask her if she wants all chocolate or if she did indeed want the middle tier to be vanilla madeira. Could do. But do I want to worry/stress the customer a couple of days before her wedding??????

What would you do?
