When the chef goes to make the cupcakes, it's a physical change.
Can i get 2 cupcakes please?
The heat in the oven is heating the muffin of the cupcake to make it rise and it to be a cupcake. That's a chemical change
Them biting into the cupcakes is a physical change because when you are chewing. But when you are swallowing it then your saliva and stuff in your body is turning it into a chemical change. And biting it you are changing the shape of the cupcake but it is still a cupcake.It is a chemical and a physical change.
