I'm apologizing in advance for asking a pricing question ...
I've done a bit of "research" on the web in my area and it seems that all well established licensed professional bakers are not quoting prices per serving or otherwise on their sites. But, the bakers that are more hobby bakers are advertising between 1.75-2.00 per serving buttercream cake. Then obviously additional costs for fondant, flowers ect. But, the 1.75 - 2.00 is the typical base cake.
I am just in the "research" and learning stage of this. I've done crazy kid cakes for my children through the years (some are posted in my pics but, many were done before I had my digital). I've even done some wedding cakes (about a dozen, most of them years ago~ some for money, some as gifts. I am definitely not a professional decorator. I just LOVE doing it. I posted the other day and got great responses and ideas on how to go about beginning putting the word out. One person suggested that I advertise as a "Student Decorator" which I loved because that says it all about my experience. But, my question is, how do I go about pricing my wedding cakes when I know I am just learning. I obviously want the bride and groom to know that they are getting a deal because they are practice for me. So, my question is "what do I charge per serving?" until I get good enough to feel comfortable charging for my craft???? I would love the practice but, obviously would prefer to get paid a little something. TIA Kristen

editted to add: I have a commercially licensed building with equipment and food license and all liability insurances in place already with my dh and my current business (small store)

If you are comfortable doing what the bride and groom request, I don't see why you should discount your work, simply because you don't have a wealth of experience. Stretch yourself on smaller projects, like party cakes. Whatever you learn from those will be transferrable to the bigger, more impressive cakes. Good luck to you.
