Not sure where to post this. I sometimes make cakes for friends, free of charge, just because I enjoy baking. A friend of a friend has asked me to make 2 for her for a work function and to "give her a price". The cakes will serve about 8 people each. She has asked for a lime cake and an orange and poppyseed one.
My dilemma - she has said that it doesn't matter how much they cost. They have a generous budget. There might also be more "cake" opportunities there, so I don't want to undercharge. But it feels really odd to charge for something that I usually do for nothing.
MN jury - how much should I charge for each cake?
