I have no idea what to charge for cakes.

8" double layer Cookies n Cream cake, for example. Like pricing ingredients and stuff seems completely implausible. I used to work at a bakery, but it's completely different than home baking. These days I mostly just bake for friends and family and charge little to nothing. But when other people, like coworkers, want me to bake for them, I'm at a loss. Edit: Oh my gosh this blew up. Thank you for all the responses, I don't think I can reply to every one, but I promise I'll read them all!
