Got a last minute order for this weekend. She wants a simple lemon bundt cake, nothing fancy, no frosting, just a glaze on it. I've never been asked to do a bundt cake before...how much should I charge?

Try doing an online search for Michigan bakeries to get an idea of the market in your area.
It wouldn't do any good to get pricing ideas from people in Texas or New York (etc.) for a cake in Michigan.
