AI have been making cakes for over 20 years, self taught decorator. I never charge enough for my cakes and people take advantage of me. I need help.with pricing. I have been asked to make a bar mitzvah cake for 90 people, sheet cake with Choc frosting ..they don't want fondant. Very plain with stars on it probably double 12x18. Should I charge per person?

I charge $80 for a double layer 12 x 18 just frosted with a border piped on.  This is a way easy cake for me to put together so I don't price it per serving.  I charge more if there is a more expensive filling inside. HTH

AThank you. How do you price custom cakes?

ACheck out the pricing formula link in my signature for more info on how to price.

Our half-sheet double layer cake (12"x18") starts at $119, and we use generous serving sizes to estimate 38-58 servings for this size cake, since single layer cakes are usually cut by the customer or a guest at the event. For 90 people I would probably recommend two half-sheet cakes unless there will be other desserts or if the venue will be cutting smaller slices.
