There are few things to consider in figuring how much you will charge for your baking goods. These are money, time and effort. I will suggest to pull out a list, notepad, a pen and a calculator. In money, try to figure out or record how much you spent on ingredients and baking tools. Next, calculate how much time you spent and you might consider a value for your time. Last, effort, how complicated to baked those goods? Does the recipe needs more study or practice?
