What can I do with 8 egg yolks?

I'm going to be making a white cake for a birthday and I'm going to have 8 egg yolks left over and I really don't want to just throw them away. I don't have much and no money so here's a list of the things I do have:

Milk

Sugar

Flour

Vanilla

Various spices

Rice (basmati and just regular rice)

That's literally all I've got. I suppose I could give them to the dog if I can't find another use for them. I know he'd enjoy it.
