You get a similar effect when walking out of a hot shower. The hot water evaporates and cools you down.
I have chosen all the different things in 3D printing than what you need. This is big picture.
Most 3d prints are not food safe, but I guess that’s no big deal for decorative cakes. It is possible to make food safe prints.
A resin printer will give smoother results for what I’ve seen but it is more messy with respect to material handling. This is probably what you should do in your case if you know you can handle less safe materials and ventilate correctly.
The most common 3D printers deposit molten plastic. These are less messy but will yield less details. You can endlessly tweak and modify them.
For modeling cartoon characters I would learn Blender.
From Blender export to Cura for slicing into layers and commands the printer understand. Others exist, I doubt Cura does resin printers.
