California

I don’t know what things are like in California, but I can tell you what I know based on my own experience and a little Google.
If you have a cfo class A you can sell to people who stop by your place to buy what you made there, and you can sell baked goods at a community event located in the county where you have the cfo registered, but that is about it.

To sell your products more broadly, which is what you seem to want to do, I think you need a cfo class B.

You both or just one might need to take a food safety class and get the basic certification, this is often required by health inspectors to be carried at events by food vendors, or it is required in iowa if you are seeking a temporary food permit for a popup location.

Usually you need to have a buisness entity established first, then you can get the different permits and licenses applied to your business. Depending on what you want to sell, your business might not need anything else other than articles of incorporation, a federal tax ID number, and the cfo class A.
The most important part is to make money! As long as you are doing the deal (making product to sell, selling your product to have some cash flow, spending cash on marketing to build up customers, keep making product to sell to your new customers and make more money, so you can make more product and so on….) you will have success.
Just jump in and start to groove, you can get all the buisness administration details figured out as they become neccessary. I think they say “fake it till you make it!” They are right!

All the solutions come easy as long as you have the most important part (cash flow) working.
Good luck!
