I don't know if I'm the first to coin it (maybe not) but the process of turning from Species A into a Pastry/Snack based alteration is what I call a Pastrification (Pastry + Transformation)
Granted the defualt rules for such a thing is simple:
Take your base (Preferrable a sona, but oc's could work)
Take your favorite treat (Pastry was the original restriction but you can honestly use other things like candies and ice cream) and that becomes your base and influences the majority of your form

For extra features use toppings creatively, such as Croissants for your long ears if you're a furry, or chocolate chips for freckles, or frosting for fluffy hair, etc etc.

Those constraints are the "faithful" method but they aren't necessary and you can stretch the process to fit the person if needed, just the further you stray the less of a pastrification (in my opinion of course) it would become.

Like if someone used bacon or steak as a base I'd struggle to classify it as a pastrification regardless of the toppings. But to each thier own!

Same for OC's you would just use their lore and what the OC likes as their base and extras instead.

Human to Pastry is easiest as you dont have to consider features such as Ears and Horns and Tails for extra topping replacements, but sometimes the challenge of using anthro to Pastry is fun and lets you be a bit creative figuring out a good "flow" for the entire piece to come together deliciously~

I just realized if you asked this in an ask this would have been a good topic to cover more publicly for others to see xD
