...and flour I hope.
I am no expert on these matters, but I don't think you can add the flour after the cake is baked.
Yes you can. Just mince it all up in a CAKE mincing machine type thing, lob the flour in, lob a few eggs in and a bit of water to make it all nice and moist again, stick it back in the oven, reglo 6 on a middle shelf.
Voila!
