I am a beginner on baking cakes, at first it was just meant for family but now I do have a couple of friends and friends of friends starting to request cake from me. I am nervous as to what to charge. I usually make basic cakes so far, plain yellow cake with buttercream icing. It did take me a while to do this cake but I am thinking it is because I am a beginner. Thank You in advance!
Your pictured c ake look really nice. Yes, there could be a few improvements but overall for a beginner it isn't that bad.
Pricing is very hard to quote. There are so many different factors to consider - including your location. You will get lots of people telling you to add up *all* your costs, including an estimate of how much electric/gas/water used and how much you want to 'earn' per hour.
I suggest y ou do spend some time figuring some of that out but as a starting point go with a basic pricing of *no less* than $50 for that size cake. I know - it sounds like a lot but once you do the figuring you will soon find out why.
