it is totally out of interest

i like to make desert and like to pratice and try different kind of desert, that's why i use every oppotunity i got to make desert for my friends, no money involoved, however, i do know someone who's doing this as a second job, they charge like $25-35 for a regular cheesecake and i think about the same for cakes, and personally maybe after i retire i would think about doing that too. :)
the cake does cost some money, and the profit margin is kinda small in my personal opinion.
